vmware 6.0

I installed server 2003 & vmware with guest os
xp. The guest had joined the domain that means it is connected to host pc but server cannot connect to the guest os.

I used remote desktop to login in the guset os but it showed me an error-“cannot open beast{pc name} u dont have rights to access this resource”.

Previously i was using vmware 4.0 & it worked smoothly. Please help me out?

Any suggestions will be “greatly” appreciated
