Recently upgraded network from W2k domain to W3k domain. Changed DNS servers. Currently running on domain controller. Problem is when you run nslookup from a client or even the dns server itself, i get sporadic "DNS request timed out. Time out was 2 seconds. ***Rquest to xxx timed-out" when I try a domain like www.yahoo.com
. What is strange is that it is sporadic. Sometimes it works, sometimes it doesn't. It is a major problem because it is affecting us sending out emails because the exchange server is getting timeouts sporadically on DNS lookups. Thought maybe the problem was with the forwarders but if I set the server to the forwarder I am using it never times out. The DNS is AD-integrated. There does not appear to be any login/computer problems from an internal windows user standpoiint. Tried to delete specific cache entries and retry but no luck. One stange item is if I do a ipconfig /all from the DNS server it list two different dns suffixes even though I have not entered any in the tcp/ip settings. But when I do nslookup it always has the cortect one. Any idea?
