I have 2 Child domains that I am seeing this same problem from. My main domain is a Windows 2000 domain with a Mixture of XP and 2000 Machines. They all work fine.
One Child domain has a Windows 2000 DC, the Windows XP machines at this location are having a problem with no getting GPO's from the server and not synching time from the server, etc. They receive error messages 1030 and 1058 (Access Denied).
My other child domain has a Windows 2003 DC and a Windows 2003 ISA Server and Windows XP machines. The Windows 2003 ISA Server and my Windows XP machines receive these 1030 and 1058 Error messages.
Any computer that is Windows 2000 works fine. It also seems like any computer that was upgraded from windows 2000 to XP works fine as well.
I have tried several of the hotfixes out there 810???, Added entry for DFS in Registry to set it to enable, nothing seems to work. I at first thought it was the Windows 2003 Child Domain DC but then I looked at my other Child domain and saw that the computers that came with Windows XP on them are not working as well.
I have not seen these issues with the Root Domain.
Please help. I have been trying to figure this out and tried quite a few things from eventsid.com (think thats the site) and nothing seems to solve the problem.
