Challenge

Veeam Backup & Replication fails to communicate with a managed remote machine with the error:
Error: The RPC server is unavailable.
RPC function call failed. Function name: [GetSvcVersion]. 
Target machine: [remotemachine.domain.tld:6160].
This article is specifically regarding the Veeam Installer Service, which defaults to using ports 6160 and 11731.

Cause

Veeam Backup & Replication is unable to reach the Veeam Installer Service on the remote machine.

Solution

Note: The service is named Veeam Installer Service, but its process is named VeeamDeploymentSvc.exe.

 

To resolve this issue, review the following troubleshooting steps:

  1. Make sure the Veeam Installer Service is running on the machine specified in the error.
  2. If the Veeam Installer Service cannot be started, check if another application is using the default port (6160) used by the Veeam Installer Service.

    Use the following command to list the PID of the application using port 6160:
    Get-Process -Id (Get-NetTCPConnection -LocalPort 6160).OwningProcess
    

    Alternatively, check within the Listening Ports section of the Network tab in Resource Monitor:
Example of spoolsv.exe locking port 6160
Example of spoolsv.exe using port 6160 and preventing Veeam Installer Service from Starting.    
  1. If the Veeam Installer Service is running on the remote machine, run the following PowerShell command on the Veeam Backup & Replication server to isolate the connection issue:
    Replace <remote_machine> with the hostname, FQDN, or IP shown in the error.
Test-NetConnection -ComputerName "<remote_machine>" -Port 6160
  1. If neither PowerShell nor Veeam Backup & Replication  can reach the port and the Veeam Installer Service is running on the remote machine, investigate whether a firewall is blocking connectivity between the two machines.

 

Other edge-case causes:

  • The Netlogon service is not running and is disabled.
  • Antivirus on the remote machine is preventing the VeeamDeploymentSvc.exe from being run.
    Process location: C:\Windows\Veeam\Backup
  • The Veeam Installer Service is not installed. In such a situation, edit the machine's entry within the Backup Infrastructure > Managed Servers section and next the pages of the Edit Windows Server wizard to force the package to be redeployed.
  • The Veeam Installer Service package was partially updated. In such a situation, uninstall the Veeam Installer Service from the remote machine. Then edit the machine's entry within the Backup Infrastructure > Managed Servers section and next through the pages of the Edit Windows Server wizard to force the package to be redeployed.

 

More Information

When creating a support case for assistance with this error, please manually zip the contents of the %programdata%\Veeam\Backup folder on the remote machine and attach them to the case. If the Veeam Installer Service cannot be contacted, the log collection tool built-in to Veeam Backup & Replication will not be able to collect the logs itself.
