I spoke too soon, that nic change didn't help. However nuking IPV6 on the DNS server and rebooting it and now things look really good. I spammed a mx lookup a 100 times on the transport server and it was ok everytime. I hope I didn't speak too soon again. I will report more in the morning.

The switch is not busy, this can be replicated on a Sunday when I am the only one around. But the NIC change may be helping. Still monitoring it from home. ________________________________________ From: Michael B.

I have two DNS servers in my main data server. One of them is pretty much limited to serving MX lookups for my single Exchange 2007 transport server. I am getting sporadic lookup time outs. I can sit at a command prompt and spam nslookups and get it to do it one time out of ten or so…sometimes more and sometimes less. But I can always make it happen. Exchange is set to use the NIC settings. Going to the DNS server itself and spamming DNS lookups and it will not happen. Switching the Exchange server to other DNS servers and it still happens. Each DNS server forwards to our ‘ISP’. Some are 2008 and some are 2008 R2. I have the extended DNS turned off.
