Ok guys, i've got a pretty crazy problem here. let me explain a little bit about the network. We have recently retired some old servers. Mainly the PDC/DNS servers and have moved those over to new machines. We also have 80ish workstations on our network. Roughly 1/3 of those are working flawlesly. We origionally had a group policy which included a few dns entry's to simply point to the old server, but that has been disabled. we wrote a login script to point our workstations to the new PDC and DNS servers. Loging into the network takes rougly 30 minuets and some of our applications work, some of them do not. Now, i've tried deleting our custom host file and replacing with a known good one and flushing the dns. Everything looks good in ip config, however. When you run a nslookup it is STILL timing out on the old IP Address. I have even tried disabling the entire group policy on the machine and user to try to get this figured out. Where else can i clear DNS out. I have also tried DHCP and i still get the same things.
Sorry if my previous post was confusing. let me try to make more sense. This is what NSlookup is reporting DNS Request Timed Out Timeout Was 2 secons *** Can't Find server Name for address 192.168.100.100: timed out Server: Unknown Address: 192.168.100.100 (192.168.100.100) is the OLD DNS Server. Ip config Reports Ip Address..............192.168.100.12 Subnet Mask.............255.255.255.0 Default Gateway.........192.168.100.99 DHCP Server.............192.168.100.98 DNS Servers.............192.168.100.97 192.168.100.96 Primary Wins Server.....192.168.100.97 Secondary Wins Server....192.168.100.25
You said you had a GPO for the old DNS server. You may need to set up a new GPO to point to the new server. Also run the gpupdate /sync on the client machine after you setup the new GPO.
