We are trying to backup our Exchange server using Veeam backup, but the server freezes. While its frozen we are seeing 95% CPU usage. The backup fails with the following error message:
[I1WHLBK01] Failed to open management RPC connection to proxy service. Port: '6162'. The RPC server is unavailable RPC function call failed. Function name: [InvokerTestConnection]. Target machine: [192.168.1.1].
The windows firewall is turned off on the exchange server.
