Client speed test failed, error -1 (unknown)


Recommended Posts

I have Retrospect Pro for Windows (build 6.5.343). One of my four Windows workstations fails to backup each time with the error "Can't access backup client, error -530 (backup client not found)" When I go into Retrospect -> Backup clients -> <client> -> Refresh, I get the error "Client speed test failed, error -1 (unknown)" This is strange because another workstation plugged into the same switch works flawlessly.


It's running W2K (latest SP) and Retrospect client 6.5.132. The strange thing is that the client is On and ready to start a backup. I've reinstalled the Retrospect backup client on the workstation. In Retrospect Pro, I've forgotten the backup client and put it back in.


I've confirmed there is no firewall on the client workstation or the Retrospect Pro server. I've also checked the network cabling and switches as well as the availability of ram, cpu, and hard drive space on the workstation. The hardware checks out.


Has anyone seen this before?

Try installing Retrospect on another one of your machines and logging in this problem client. If that fails too we can assume this is a problem with the client machine.


You might want to uninstall and reinstall the network drivers on the problem client machine.
