Network – RPC server in unavalible 0x800706BA

Hi all,

I am trying to back up my networked PC’s (Vista64 Home Premium x 3) to a Network drive however when i use the ‘BackUp and Restore Center Software’ i get the error
‘RPC server in unavalible 0x800706BA, Please ensure the network location is valid’
I can map the dive, i can install folders and files to it, but i can’t back up to it.

Any ideas folks?
