PC Anywhere connecting to remote

Attempting to login into a system running XP, system was working fine until a power loss. The XP is on an UPS. The XP is the remote login in via Ethernet to a NT box, the NT unit is not on UPS. However the NT to XP link came up with no problems and is working fine. When trying to connect to the XP box from a remote for support the following message is received:

 

"The selected computer is not responding the connection cannot be made"

 

Once again, this all worked fine until the power loss. Does anyone have any suggestions
