I'm having a strange problem at one site. I can add computers to the
domain during setup. But when trying to logon to the domain, the
computers first displays the greyed out logon box end then nothing but
the standard blue background.
The problem first occured when I had changed some registry values (as
described in this NG) to make XP browsing faster. I immediately
changed those settings back to their normal value. When I'd changed
those values back the computers that hadn't been started up for the
day could logon, but the ones that had been started directly in the
morning had to logon locally and access the resources on the server
from there. All this happened a few months ago, but I didn't do much
to solve the problem then. I planned to reinstall the "faulty"
computers at a convinient occassion.
But when I added two new computers the other day, I got same problem.
They are added to the domain, but can't logon to the domain. Now I
have eight computers that can't logon to the domain and four who can.
All computers running WinXP Pro SP1 with the latest patches.
Anyone having any ideas where to start looking? I've been thinking
about using packet sniffers, but I really don't know what to look for.
Any help would be greatly appriciated.

The ipconfig /all from the server looks like

The output from the workstation is in Swedish, hope you can understand it anyway.
