2008 R2 accessing Shares on 2003 server

Hello

I have a 2008 r2 server (RDPServer) that cannot access any shares from a 2003 server.

Other servers are able to access the 2003 server shares.

The only error is simply "The server cannot perform the requested operation".

I can ping the 2003 server from the RDPServer.

Any ideas?

Thanks,

Jason
