slow PC after server replacement

C

cpu

Here's a weird one for experienced sysadmins out there.

Company has an old NT 4 network. File server is a Win2000 member server
which has been decommissioned and removed and replaced with a Win2003 member
server. Staff member with modern PC running WinXP Pro complains ever since
the migration her PC has been really slow. And she is right!

Note: logon scripts automatically removed mapped network drives to old file
server, and re-map network drives to new server.

Here's how it is slow.
Click Start->Run. Type 'winword' and Press <ENTER>. Word 2003 does NOT come
up even though the machine is still very responsive. CPU activity is around
0% (zero percent) with virtually no disk activity.

Click Start->Run. Type 'excel' and Press <ENTER>. Still nothing.
Click Start->Run. Type 'notepad' and Press <ENTER>. Still nothing.
After several more moments, ALL 3 applications appear!!!

Sounds like XP is searching the PATH environment variable. A quick look and
indeed it is!! I remove the offending old file server from the PATH
statement and rebooted the machine. Before I reboot I save the original PATH
statement as a text file.

Note: I am logged in as another user with administrator privileges. The
staff member also has administrator rights on the PC however the PC is not
connected to the Internet and has only a modest set of applications
installed.

PC has now been rebooted. A quick test shows that Winword, Excel and Notepad
now starts up quickly!!! I thought the problem was solved..... until.... I
double clicked on the tiny text file I created earlier. It took a VERY long
time to open. Staff member shows me one of several small GIFs that also take
an incredibly long time to open. She assures me everything was working just
fine prior to the file server replacement.

I can't see anything wrong in the Event Viewer. Any suggestions what could
be wrong?

Check your DNS settings. Modern Windows servers do DNS differently than NT4
did. The server should point to itself for DNS with forward/reverse lookup
zones for the Internet. Workstations should only look to the server.
