Installed services

The installer creates the following Windows services:

  • ds-docservice — the main document editing service
  • ds-converter — handles document format conversion

You can manage these services via the Services panel (services.msc) or the command line:

net stop ds-docservice
net start ds-docservice

Configuring Windows Firewall

After installation, you may need to allow ONLYOFFICE Docs through the Windows Firewall:

  1. Open Windows Defender Firewall with Advanced Security (run wf.msc).
  2. Click Inbound Rules > New Rule.
  3. Select Port, click Next.
  4. Select TCP, enter 80 (or the port you configured), click Next.
  5. Select Allow the connection, click Next.
  6. Select the network profiles that apply, click Next.
  7. Name the rule (e.g., "ONLYOFFICE Docs"), click Finish.

Verifying the installation

After installation, open http://localhost (or your server's IP address) in a browser. The ONLYOFFICE Docs welcome page should appear, confirming that the installation was successful.

If the welcome page does not appear, check the following:

  • Make sure the ONLYOFFICE Docs services are running. Open Services (services.msc) and verify that ds-docservice and ds-converter are in the "Running" state.
  • Check the logs at %ProgramFiles%\ONLYOFFICE\DocumentServer\Log\ for error messages.
  • Make sure Windows Firewall is not blocking the port. Open Windows Defender Firewall (wf.msc), go to Inbound Rules, and verify that a rule allowing TCP traffic on port 80 (or your custom port) exists and is enabled. If it does not exist, see Configuring Windows Firewall.

Silent installation

Before initiating silent installation, make sure you have the prerequisites installed:

onlyoffice-documentserver-prerequisites.exe
The prerequisites installation supports the /SILENT flag.

For automated or scripted deployments, run the installer with the /SILENT flag:

onlyoffice-documentserver.exe /SILENT

To also specify a custom port:

onlyoffice-documentserver.exe /SILENT /DS_PORT=8080

Offline installation

If the target machine does not have internet access, download the prerequisites package separately:

Antivirus exclusions

Some antivirus software may interfere with ONLYOFFICE Docs services (e.g., blocking Node.js processes or scanning temporary files during document conversion). If you experience issues such as slow conversions or services failing to start, add the following directories to your antivirus exclusion list:

  • %ProgramFiles%\ONLYOFFICE\DocumentServer\
  • %ProgramData%\ONLYOFFICE\
