Cannot connect to one of network share

[Buck]

I get a similar message but mine reads as follows:

Mshome is not accesible. You might not have permission
to use this network resource. Contact the administrator
of this server to find out if you have access permissions.

Mshome is the name of my home network.

Any ideas?
