We have two seperate domains running on our network.  They are windows 2003 servers with AD & DNS.  Neither of them can access www.microsoft.com.  The to domains are totally seperate from each other other than sharing the same Internet connection.  I have scanned the heck out of the servers and a workstation.  MS updates and AV are all uptodate.  I have cleared the cache in the dns server.  done an ipconfig /flushdns.  If i do an nslookup, it comes up with a valid IP Address that from any other network will go to www.microsoft.com, but not any computers on this network.  I cannot ping any of the IP Address for www.microsoft.com.  I have install Firefox and it will not work.  

A little direct please.

I will try rebooting the firewall tonight.

It is not in the blocked list but i am starting to suspect the firewall.

I have powered off the firewall and powered it back on.  It is not setup to block websites.

I went to a workstation and changed the DNS to the DNS of the ISP so as to not use the domain DNS.
Same results.
ipconfig /flushdns a few times in there also.

This sounds like the conflicker virus.

Here's a tool that will probably help with scanning your networks.

The problem was in the firewall.  It was not blocking it in the blocked sites, but I think the routing tables may have been messed up.  Doing a traceRT seemed to go through.  Power it off for a few moments and back on fixed the problem.  WatchGuard Firebox 700
That would have cleared the ARP cache. Could also have been an issue, and would have reset the routing table on rebooting.
