Had a problem that started Friday- For some reason, some DNS requesta do not seem to be resolving. I am using MS DNS server on a sbs, all the clients point to the server as the DNS server. I have2 forwarders to 2 different ISP dns servers enabled. When I do an nslookup, i get a response. from internet exploiter, i can go to sites like google and yahoo, but not microsoft.com, msn.com,and mapquest.
i have scavenged all stale records, cleared my cache,andrestarted the server. if i change a client to not use the server as its dns, it works fine.
dunno if it makes a difference, but ialso have a particular client that has incredibly slow login times, too.
