This operation returned because the timeout period expired windows 7

[B_W_IT]

I have a new Win 7 Dell Precision Workstation that will not log in to my domain. I get an error that there is no login server available if I attempt to log in using a domain account. I log in as the local admin and then try to join a domain using the Join a Domain or Workgroup wizard. I then get an error stating "this operation returned because the timeout period expired". I have had to reset my core switch to get a couple of the new boxes (including this one) to even join the domain. I also show no internet in the Network and Sharing Center most of the time.

Try it on another network jack, or try a different network card in the PC.

Thanks for the assistance but it was a little more involved than that. I received the following link from HP (my core switch). Once I changed the reg key, it worked!
