We have 15 identical Dell laptops running Windows XP Pro SP2 with all the updates. I setup the first one exactly the way we want it and then cloned that laptop's hard drive image to all the others.
I joined 5 of the laptops to our Windows Server 2003 domain and found that it takes 10-15 minutes to login when using a domain user account, but logins are fast when logging in locally.
I did some research and learned that identical SIDs on each laptop might be the issue, so I found a utility called NewSID at:
I removed one laptop from the domain and used NewSID to give it a new random SID. I then rejoined it to the domain, rebooted, and it logged in fast!
I thought for sure that I had found the fix, so I removed all the laptops from the domain (including the fixed one for some ridiculous reason), gave them all new random SIDs, and rejoined them to the domain. Much to my dismay, they were all back to the old problem of taking 10-15 minutes to login on any domain user account (even a domain admin).
Thanks in advance!
