Windows 2008 Server R2 Domain resources, ie.. computers, printers are taking a long time to discover and show changes.

I updated my network from SBS 2003 to Windows 2008 R2 a few months back, and am noticing some poor performance in showing network resources, and acknowledging changes. On a Windows 7 computer when I click on Network in Windows Explorer it takes several minutes to show the list, sometime it doesn't show at all. Same on my XP machines. It doesn't do this every time though, occasionally they come right up.

My latest test that really shows this is a simple HP printer. I loaded it on one of my Windows 2003 x64 servers. I loaded it's IP address and added the universal PCL driver and it prints fine from the server. I add it to my local Windows 7 system and it completes. When I try to print a test document, it shows offline, then after anywhere from 3 to 10 minutes, it will print the page. At that point it print okay. I changed the share name, reloaded the printer it takes the same 3 to 10 minutes. It also does this when I unplug the printer and reconnect it.

These problems may not be related, or I might not have enough information. Let me know what you need me to post for better info.

Can you run dcdiag on your DC to check for errors.

Your systems and DC should be pointing to the DC for DNS only there should not be any external DNS servers listed.

Make sure Netbios over TCP\IP is enabled in the TCP\IP settings.

My apologies for being so late...2 months almost in getting back to this. I have had a number of other problems that outwieghed this one. From some reading I have been able to do, others seem to be having similar problems. Are there any known issues with this on Windows 2008 R2 and Windows 7?

I found the answer to this, thanks to everyone for their comments. It was a Master Browser and Election issue. Windows Server 2008 does not automatically set themselves as MB's, which in thinking, is a good thing.

I am not sure how to give out points on a question like this. Darius did put time into the question, which makes me think he deserves something for his time.
