Network computers list flashing

OK, Here's one I've never seen before. I'm running AD on a Win2k8 64bit server. Suddenly, this morning it started displaying the network computers list in Explorer in a strange way. The list is being displayed two or three computers at a time for a second at a time. Then the list will refresh with other computers in the domain being listed for a second before being refreshed again. And so on  and so on, repeatedly cycling through the whole list. The other computers in the domain are well behaved.  What is this all about?  Any suggestions for a remedy?  Thanks for any help.

Try rebooting the switches and routers.

I had tried robooting the Sonicwall router this morning and it made no difference. I just now rebooted the Sonicwall and three switches we have and it made some difference. The list refreshes slower now, but it still refreshes and shows parts of the list. I think it's something having to do with this one computer. It doesn't happen on any other machine, and it started this morning after an overnight MS update. So maybe something got broken then.

If you are unable to reboot the server simply log all users off of that server and then log back on and see if that resolves; also check task manager--my guess is it is windows explore that is the culprit

Last night I realized I had rebooted everything except the server itself. So I rebooted and that seems to have done the trick. I wanted to wait until this morning to confirm the solution. Apparently Explorer on the server loaded incorrectly, so the reboot is the solution.  Still. very strange incident. Thanks for the suggestions.

OK, here's a belated update. I found out that this problem was being caused by a IP address conflict. Somehow, the IP's for the server had been changed from static to dynamic and one of the NICs IP was causing it to work intermittently, in turn causing the network section of Explorer to flash. I corrected the issue by inputting all the static IP's as they should have been and the problem disappeared.  FYI
