I have had somewhat similar problems in the past with Windows Update that were apparently caused by using OpenDNS for my external resolvers, and thereby receiving sub-optimal responses for Windows Update-related sites. update.microsoft.com is a small maze of distributed sites, and for a while earlier this year if I used OpenDNS at work it would often take > 5 minutes to load any pages (on XP, etc.). I went so far as chasing down all the related domains I could find (nsatc.net, etc.) and putting in conditional forwarders for them to DNS servers other than OpenDNS.
YMMV, but I did see drastically improved Windows Update performance after adding the forwarders and moving resolution of update.microsoft.com, microsoft,com, www.update.microsoft.com.nsatc.net, and a handful of others away from OpenDNS. (Having said all this, I don't think that OpenDNS' responses were/are invalid. I think that probably what happened is that for a while I was being sent to destinations that just didn't perform very well. PS You have 2 DCs at your house? On Tue, Jan 5, 2010 at 7:32 PM, Steven M.
