This is a user specific issue and doesn't seem to be related to the
machine. A second user can log on and access the network resources
from this machine and the first user connects using the same method on
a second machine and encounters the same problem.
I've contacted Microsoft Product support and they recommend I contact
the computer vendor, but Im pretty confident that its a OS issue.
Thanks for any and all advice
