Virtual Server 2005 – Guest OS access issue.

Host: W2K3 SP2 w/Virtual Server 2005
Guest: W2K3 Ent R2

I am having access troubles with my Guest OS. The Guest joined domain successfully. I can see my network resources just fine, but when I try to run an executible it fails.

“Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item.”

Even when copying the executible to the Guest and running there generates the same error.

I know there is something up with the delegating of rights between the Host and Guest but I cannot seem to find it. Any help would be appreciated.
