Upgraded server from 2k to 2k3.  Left the old server online to varify all data has successfully been xfered to new server.  Disconnected LAN cable from old server and the LAN went nuts.  Realized that Old server needs to be demoted off of LAN.  DCPROMO'ed old server successfully.  Now when I attempt to access "My Network Places >> Entire Network >> Microsoft Windows Network >> <Domain> I receive error "<Domain> is not accessible.  You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.   The list of servers for this workgroup is not currently available."  I also received this error when I unplugged the lan connection before I DCPROMO'ed the old server.
I receive this same error even if I attempt to access the network from the new server.

What did I miss? and How can I fix the problem?

Did you move all the FSMO roles to the new server?  You also want to make the new server a GC.

Here are some articles:

You'll find how to make the DC a GC under Managing the Global Catalog.

I checked the new server and it is listed as a GC.  I do not know, however, how to check if the FSMO roles were moved.  How can I check?

All the FSMO have been transferred already to the new exchange server.  Should they be moved to the Main file server?

As long as they are on a live DC, they should be fine.  Restart the Netlogon service on the Exchange server.  Be sure it only points to your DNS server first.  Rely on Forwarding from your DNS to the ISP for Internet resolution.

I found the problem.  When I changed the FSMO over to the file server from the mail server I was able to get in.  I had to however, disable the GC from the main file server  in order to switch the Infrastructure Master.  Once I did that, I went to My network places >> entire network . . . and found only 3 computers in the domain listing.  I went to the mail server and re-enabled the CG.  Now I am back in action.

Thanks for your guidance.  You pointed me to the right direction.

Not excellent.

I went to another pc that was having difficulty and received this error

"<Domain> is not accessible. You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.  
No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept."

Should I start a new question or is this an extention of the same issue?

Is there a limit to the number of connections the domain can accept?  How do I change that?
