host is unreachable

host is unreachable

I'm using the free admin tools and whenever i use the Shutdown/restart or GPO update tool i get the message Status: Failed and Remarks:  Host is not reachable. The workstation is running windows 7 enterprise 32 bit with SP 1 and the server is 2008 R2 Enterprise 64 BIT. The tools worked when the workstation was XP  PRO, but now the tools wont work on the station, even thought the workstation sees the server and the tools see the workstation. Any feedback will be great.
