The 5 most common IT problems in small businesses and how to solve them

Introduction

Running a micro or small company in Poland means that owners and managers often care about equipment and software themselves. The lack of a dedicated IT department causes even a minor failure to paralyse the work of the entire team: the inoperative mail, a hard printer or a free computer stop customer service and generate real losses. Worse still, many entrepreneurs do not know where to look for help or how to prevent similar problems.

This article highlights the five most common IT problems in your business and discusses simple steps anyone can take to solve or prevent them. We will also present when it is worth considering IT outsourcing and remote helpdesk, and we will advise how to ensure data security in accordance with the 3-2-1 rule and GDPR requirements. Thanks to practical examples from the life of Polish SMEs and explanations of technical jargon in the language of benefits, the article will help you assess which tasks can be performed on your own and which ones are better to rely on specialists.

No access to corporate mail: What do you do when Outlook or Gmail refuses to obey?

Not being able to send or receive emails is one of the most stressful IT problems. An employee sees an error message, an attempt to send a message results in a failure message, and customers do not receive offers. The reasons may lie in the DNS configuration, authentication errors, an overflowed mailbox or a failure on the provider's side.

Why is this happening?

• Invalid DNS/MX records: DNS entries indicate which server the mail goes to. If MX records are incorrect or missing, messages may not reach, return with a mistake, or hit the wrong server. Some companies forget to update records after changing hosting or migration to Microsoft 365/Google Workspace.
• Mailbox full: older IMAP accounts have small limits. When the box is filled, the new messages do not arrive, the senders get a message about a lack of space and the user cannot save the work emails.
• Incorrect password: blocked account or 2FA problems, common causes include recent password changes, requiring additional confirmation (2FA), or account lockout after multiple failed logins.
• Connection or certificate issues: if the Internet in the office is unstable or e-mail ports (25/465/587/995) are blocked by firewall, the postal client will not connect to the server.
• Supplier failure: Less often, but breaks are possible on the part of the service provider (e.g. Microsoft 365, Google Workspace). It is then worth checking the service status.

Quick step by step solution

• Check your internet connection: Open several pages to make sure the connection works.
• Log in via webmail: if the mail through the browser works, the problem lies in the mail program (e.g. Outlook). Reset your password or re-add your account.
• Verify DNS/MX records: Use the MXTtoolbox tool to check if the MX records indicate the right servers.
• Delete unnecessary messages: If the box is full, remove large attachments or ask your supplier to increase the limit.
• Reset password and check 2FA: refresh the credentials in the mail client, make sure that two-step authentication is enabled (if your provider enforces it). 2FA authentication requires two forms of identification and makes it much more difficult for hackers to take over your account.
• Contact the supplier: If the problem persists, check the status of the service provider or consult the specialist.

Short checklist: company mail

• Organised DNS configuration and MX record updates after each hosting change.
• Regular inbox cleaning and archiving of old messages.
• On 2FA and strong, unique passwords (using password manager).
• Monitor webmail limits and error messages.
• Box backups (archiving in PST/ZIP format).

Printer Problems: When a document does not want to be printed

Printers are still an important tool in offices: invoices, contracts and warehouse documents require a paper version. When the device stops printing, work comes to a standstill. Users see a jammed print queue, an "offline" message, or no response to a print command.

Why is this happening?

• Incorrect or invisible connection: Printers may have trouble connecting via USB, Wi-Fi or LAN. Tips recommend to turn the printer off and restart and then check the cables and wireless connection. Make sure that printer and computer are on the same network and that wireless communication is enabled.
• Drivers and operating system: no current drivers or incompatible version of Windows can cause errors. On computers with ARM processor, the manufacturer's installers may not work; in this case, it is recommended to add a printer in system settings instead of using a dedicated installer.
• Jammed print queue: To-dos can get stuck in the printer buffer. Helps to disable and enable the printer or restart the buffer service in the system.
• Invalid IP address of the network printer: If the device has a static IP address outside the VLAN or DHCP network range, the computers will not find it.

Quick step by step solution

• Turn the printer off and on by disconnecting it from the power source for 30 seconds.
• Check the USB cable or network connection, make sure in case of Wi-Fi the device is on the same network and the signal is strong.
• Delete jammed jobs, in Windows open "Printers and scanners", select the device and click "Open queue"; remove blocked tasks.
• Reinstall the printer, uninstall the device, and add it again in "Printers & Scanners".
• Update drivers, download the latest software from the manufacturer or use Windows Update.
• On the VLAN, set a static IP address in the appropriate range or enable DHCP.

Short Checklist: Printers

• Saved steps: restart, check cables, reinstall.
• Regular updating of printer drivers and firmware.
• Network printer configuration with DHCP address reservation (or static IP) in the appropriate subnet.
• Periodically clean the inside of the printer (according to manufacturer's instructions) and replacement of consumables.
• Access to the printer's administration panel is password-limited.

If your printers are often suspended and you do not have time to diagnose the network, use constant IT care with helpdesk: NexaIT team will help you remotely restore the operation of the devices.

Free PCs at work: causes and acceleration

The team uses computers every day, and slow system operation irritates employees and reduces their efficiency. Symptoms include long system startup times, stuck applications, the browser sluggishes with several tabs, or sudden program hangs. Slowdowns most often result from several specific factors.

Why is this happening?

• Programs launched with the system: A lot of unnecessary applications start on every computer on, which significantly prolongs boot time. It is worth to open Task Manager and disable unnecessary items.
• No updates: Windows and drivers require regular patches. Old versions may contain errors affecting performance.
• Low RAM: With insufficient operating memory, the data is transferred between RAM and disk, which slows down the system. It is worth considering adding RAM, especially when it is less than 8 GB.
• Malware and viruses: malignant software uses resources, causing slowdowns. Regular antivirus scanning and avoiding installation of unknown applications is necessary.
• Overflow or old disk: The full hard drive limits space for temporary files, and the HDD is much slower than the modern SSD. The exchange of HDD to SSD usually significantly reduces system start-up and open-up applications.
• Dust and overheating: Contaminated cooling causes overheating and automatic lowering of processor tacture.

Quick step by step solution

• Open Task Manager (Ctrl+Shift+Esc), go to the "Startup" tab and disable unnecessary applications.
• Enable automatic system updates and install the latest drivers.
• Check the amount of RAM; if you have less than 8GB, consider expanding it.
• Run a full virus scan and uninstall suspicious programs.
• Clean disk, remove unnecessary files and applications, use built-in disk cleaning tools.
• Consider replacing your HDD with an SSD; it's an investment that dramatically improves performance.
• Turn off the computer, disconnect the power and clean the inside with compressed air.

Short checklist: computers

• Regular system and driver updates.
• Scheduled antivirus scanning (preferably with the EDR/AV, endpoint protection tool).
• Minimise startup programs; install only necessary applications.
• Monitoring disk health (SMART) and free space.
• Equipment maintenance: dust cleaning at least twice a year.
• Replacing old computers or upgrading (SSD, RAM) according to your budget.

If your employees are wasting time waiting, check constant IT support: We will propose upgrading equipment and remote monitoring of computers.

Network and Wi-Fi problems: an unstable connection in the office

An unstable network is another problem for small companies: websites are long loaded, videoconferencing jams and network printers are not available. Causes may be prosaic: from the wrong router setting to the wrong DHCP configuration.

Why is this happening?

• Jamming and range: The router set next to the microwave or in the metal cabinet is exposed to interference. It is recommended to keep the router away from sources of interference (microwaves, Bluetooth devices, etc.) and reducing the number of simultaneous clients. The antennas must also be properly positioned (45 degree angle or vertical) and move the devices near the router.
• Congested channel Wi-Fi: in blocks and office buildings many networks operate on the same channels. It helps to change the channel and bandwidth, and, where possible, use the 5 GHz band, where there is less interference.
• Old router firmware: Obsolete firmware can cause instability and security gaps; update is recommended.
• Incorrect DHCP/DNS configuration: too small an IP address pool, collisions of addresses or disabled DHCPs can cut some devices off from the network. Also the lack of a local DNS server or an error in VLAN configuration may cause a lack of Internet access or printers.
• Cabling: used Ethernet cables, lack of shielding or incorrect length can cause interference.

Quick step by step solution

• Move the router: Set it in the open space, away from sources of interference; set the antennas at an angle and raise the device.
• Change channel and band: Log in to the router panel, set channel 1/6/11 in the 2.4 GHz band or activate 5 GHz.
• Update firmware: download the latest version from the manufacturer's website and upload it through the administration panel.
• Check DHCP and IP range: Make sure the DHCP server is enabled and has a sufficient address pool; set up appropriate subnets in VLAN.
• Replace damaged cables: Replace old cables into category 5e/6 cables.
• Run speed tests: Check whether the problem is on the supplier's Internet, and possibly report the complaint.

Short checklist: Network and Wi-Fi

• Central positioning of the router in the office; avoiding interference.
• Change the password to Wi-Fi and disable the factory SSID.
• Regular firmware update and VLAN configuration for the guest network.
• IP address reservation for key devices (servers, printers).
• Monitor network load and number of connected devices.

Backup and user safety: backup, GDPR, phishing and 2FA

Losing data or violating privacy can ruin the reputation and financial stability of a small company. Ransomware and phishing attacks are so common today that the lack of basic security is a huge risk. It is worth implementing some simple standards.

Rule 3-2-1: foundation of backup

The basic backup strategy is rule 3-2-1: three copies of data, two on different media and one in another location. This means that even a fire, a robbery or cyber attack doesn't have to mean losing data.

How to implement this principle in a small company?

• 3 copies: production data (on server or computer) and two independent backups: e.g. local external disk and cloud (OneDrive, Google Drive, dedicated backups).
• 2 different media: not three identical disks in the same place. One backup can be in the cloud, the other on the network drive (NAS) disconnected from the network.
• 1 off-site copy: stored in another location (e.g. in the cloud or in a vault in another office).
• Regular playback tests: A copy without a test is useless.

2FA: additional layer of protection

Two-factor authentication (2FA) is a method that requires two forms of identification to access resources. With 2FA, companies can monitor and protect critical information and networks. The most popular methods are SMS codes and mobile applications (e.g. Microsoft Authenticator) or hardware tokens.

How to enable 2FA in your company?

• Activate 2FA on your email services (Microsoft 365, Google Workspace) and work tools (CRM, ERP).
• Require 2FA to log in to admin panels (routers, NAS servers, hosting panels).
• Use apps that generate one-time codes (TOTP)'Cause they're safer than texting.
• Make sure employees have secure recovery methods set up so that a single phone failure doesn't lock out an account.

Phishing and user education

Phishing is one of the most popular attacks based on e-mails and text messages. Cybercriminals impersonate courier companies, offices or friends to obtain login details. Phishing emails often contain language errors, incorrect sender addresses, shortened links, and demands for immediate action.

How to protect your company against phishing?

• Training and awareness: regularly inform your employees about the methods of identifying false messages: grammar errors, strange addresses, unexpected attachments.
• Be careful with links: Do not click on links from unknown emails; check the full URL by invading the link with the cursor.
• Use anti-spam filters: Configure filters in mail and gateway, enable SPF/DKIM/DMARC policies.
• Incident reporting: Suspicious messages signify as spam or report to CERT Polska.

Data protection and GDPR compliance

GDPR requires entrepreneurs to protect the personal data of customers and employees. For small companies this means, among others: media encryption, limiting file permissions, periodic testing of backup copies and keeping a register of incidents. It is worth separating permissions (principle of least privilege), apply password policies, enable EDR/AV (advanced antivirus) and regularly conduct IT audits.

Short checklist: backups and security

• Implementation of the 3-2-1 strategy with automatic backup to the cloud and to local media.
• Enable 2FA on critical services (mail, cloud, administration panel).
• SPF, DKIM and DMARC configuration for the domain to reduce spoofing.
• Employee education in the field of phishing and safe use of the Internet.
• Encryption of laptops, portable media and NAS drives.
• Documentation of security procedures and regular backup recovery testing.

When should you consider IT outsourcing and remote helpdesk?

Small businesses often try to solve IT problems on their own, which takes time and distracts them from key business tasks. IT outsourcing and remote helpdesk are services in which an external team of specialists is responsible for infrastructure, user support and technological development.

Benefits for micro and small companies

• Save time: instead of spending an hour looking for mistakes in mail, printers or networks, employees focus on the customer.
• Access to specialist knowledge: The external team knows standards, procedures and tools, making diagnosis and repair faster.
• Predictable costs: subscription to IT outsourcing or remote helpdesk facilitates budget planning; you do not pay for every phone.
• Security and compliance: specialists care about backup, updates, 2FA, GDPR; implement solutions that protect the company from data loss.
• Access to innovation: NexaIT advisors will give you a hint on how to use AI and automation to improve business processes.

When does it pay off?

• When there is no dedicated IT department and employees spend more and more time solving failures.
• When your company grows and needs scalable infrastructure (e.g. migration to the M365 cloud or Google Workspace).
• After a security incident or major failure where an audit and remediation plan is required.
• When you need access to specialists without hiring a full-time job.

If you are considering outsourcing, please order contact, we will offer a support package tailored to your company.

Security and backup in a small company: simple standards according to GDPR

GDPR requires companies to take adequate organisational and technical measures to secure personal data. For micro and small enterprises, this means not so much expensive systems, but simple but effective procedures.

What is worth implementing?

• Log of processing activities: a list of processes in which data are processed (e.g. recruitment, customer service).
• Password Policy: Long passwords or phrases, password manager, change password after suspected leak and ban the use of the same password in several places.
• Role-based permissions: employees have access only to the data needed for work (principle of least privilege).
• Encryption and 2FA: Encrypting laptops and portable media drives, as well as including dual authentication in business systems.
• Business Continuity Plan: a document describing how to restore work after failure (backup procedures, contact list, action steps).
• Regular audits and tests: checking configuration, penetration tests and backup attempts.

The above actions increase security and minimise the risk of financial penalties for violating the GDPR. You can automate many of them thanks to remote monitoring and backup tools.

Summary: The key is proactivity

IT failures happen to every company. However, in small organisations they can paralyse operations because there is no one to repair them. The most common problems include broken email, stuck printers, slow computers, unstable Wi-Fi, and lack of backups. Most of them can be prevented with simple practices: regular updates, configuration monitoring, employee education and implementing security policies (3-2-1, 2FA, password policies). . Using professional IT outsourcing and remote helpdesk allows you to master serious incidents more quickly, and the company will be able to focus on its business.
