Question : Long Delay Opening Files In Windows Explorer, Phantom IP Addresses

This problem ocurrs on a single workstation on a domain that has had the domain controller recently replaced with a new box at a new IP.   All files in all programs, local or network drives take an exceptionally long time to open when double-clicked in explorer, 50-80 seconds.  Once open the files respond normally.

The symtoms and troubleshooting are almost exactly like this previous issue:

I have narrowed my problem down to a phantom IP address that is the old domain controller.  Here is the output from the netstat -a command:
Proto  Local Address          Foreign Address        State

192.168.1.202 is the old server.  I have scoured the registry for any entry related to this IP address, drive mappings or explorer settings.  I have disjoined the PC from the domain and rejoined.  I can't get at it and really don't want to reformat this user's PC.  Any ideas would be greatly appreciated.

Make sure the old server has been removed from active directory and from your DNS server.

I assume you checked the network settings of the workstation to make sure it wasn't listed as one of the DNS servers?
