I had this same issue and this is how I fixed it. Get MS Article: 304624 (http://support.microsoft.com/default...b;en-us;304624
). This talks about configuring the Group Policy for Active Directory. If your connecting to an NT domain you can have the same problem. There is a Group Policy on XP Pro. Complete the following to fix:
1. Start / Run, enter MMC select OK.
2. Select Add/Remove Snap-in.
3. Select Add and select Group Policy and then select the defaults to get back to the MMC.
4. Follow from step 6 in MS Article: 304624.
You may have to reboot to finish.
Hope this solves your issue.
