Amend the company file to use the IP address on your computer
- Browse to the relevant folder:
Sage Accounts v33 C:\ProgramData\Sage\Accounts\V33
Sage Accounts v32 C:\ProgramData\Sage\Accounts\2026
Sage Accounts v31 C:\ProgramData\Sage\Accounts\2025
Sage Accounts v30
C:\ProgramData\Sage\Accounts\2024Sage Accounts v29 C:\ProgramData\Sage\Accounts\2023 Sage Accounts v28 C:\ProgramData\Sage\Accounts\2022 Sage Accounts v27 C:\ProgramData\Sage\Accounts\2021 Sage Accounts v26 C:\ProgramData\Sage\Accounts\2020 - Double-click the Company file and choose to open with Notepad.
- Change the paths in the company file, replacing the server name with the IP address. For example, if your server IP address is 123.456.789.111, and your shared folder is Sagedata, the UNC path is \\123.456.789.111\Sagedata

The Windows DNS cache stores your recently viewed pages by IP address. You can’t access the page if its location changes before you update the entry in your DNS cache. The IP address for the Sage Accounts Data Service is dynamic, which means it can change. If the DNS cache stores the IP addresses and doesn't update, this causes a connection issue to the service. Clearing the DNS cache can resolve this.
- Stop the Sage Accounts Data Service.
- Press the Windows key + R and type ipconfig /flushdns then press OK.
- Start the Sage Accounts Data Service.

Further Troubleshooting steps
We advise that your local IT support follow these steps.
▼ Remove read only and hidden attributes
- Obtain the address of company.0** folder, for example S:\SageData\Company.000.
- Press the Windows key and R on your keyboard, then type CMD then press OK.
- Type CD and the path to the data, for example CD S:\SageData\Company.000, then press Enter.
- Type attrib -h -r /S /D then press Enter.
- The -h removes the hidden attribute
- The -r removes the read-only attribute
- The /S ensures this applies to all files in the folder
- The /D ensures this also applies to all the sub folders
- Close the command prompt window.
Check the following:
- Test access to 127.0.0.1 (local PC) to check for tcp/ip faults on your network adapter
- Test the server IP address from the client computer. This ensures they're not using a distributed file system and that the data service is installed where the files are being distributed from
To test access to the IP addresses, you require on the client computer:
- Press the Windows key and R on your keyboard, then type CMD, then press OK.
- At the Dos prompt, type ping 127.0.0.1, then press Enter.
For the server, repeat this replacing 127.0.0.1 with the server IP address.
To check the server IP address on the client computer:
- Press the Windows key and R on your keyboard, then type CMD, then press OK.
- Enter ping servername then press Enter.
If you receive the following message, the system can't find the data service on the server or there's a fault with the network adaptor:
'Ping request couldn’t find host xxxx.sage.com'.
Update the File Path Using the IP Address
- Locate your company file from the following path, the C: to location data is stored on.
| Sage Accounts version | Default data path |
|---|---|
| Sage Accounts v33 | C:\ProgramData\Sage\Accounts\V33 |
| Sage Accounts v32 | C:\ProgramData\Sage\Accounts\2026 |
| Sage Accounts v31 | C:\ProgramData\Sage\Accounts\2025 |
| Sage Accounts v30 | C:\ProgramData\Sage\Accounts\2024 |
| Sage Accounts v29 | C:\ProgramData\Sage\Accounts\2023 |
| Sage Accounts v28 | C:\ProgramData\Sage\Accounts\2022 |
| Sage Accounts v27 | C:\ProgramData\Sage\Accounts\2021 |
| Sage Accounts v26 | C:\ProgramData\Sage\Accounts\2020 |
- Right-click on the "COMPANY" file, and select Open with.
- Choose Notepad and press Just once if it gives you the option.
- Replace the start of the data path with the IP address before the backslash "\".
- Go to File then select Save.
▼ Check for mapped drives on a computer and change to UNC paths
TIP:
This also advises how to get the IP address of the server.
- Press the Windows Key, type cmd, right-click cmd.exe, then choose Run as admin.
- Type Net use then press Enter.
This shows all mapped drives for the computer you run the command on. - To get the server IP address, enter nslookup server name.
- Change any mapped drives to UNC paths.
In some circumstances, the problem is related to the customer using a IPv6 IP address. To resolve this either switch to the IPv4 IP address, or disable the IPv6 address on the local network. For further help with this, refer to your local IT support.
1. Hold down the Windows key and press R.
2. Type Control Panel then select Network and Internet.
4. Select Network and Sharing Centre, then Change adapter settings.
6. Right-click your connection and go to Properties.
