We just now upgraded to Windows 2003 Active Directory and have noticed that our Windows XP SP2 clients are booting vert slowly and stuck for 2-3 minites on the "Applying Computer Settings" screen. Most of the articles that I have read about this issue tells me issues surrounding DNS, but I dont know that our DNS is setup properly or not. We are using the split brain dns solution. The internal Dns servers run Windows 2003 server and are also domain controllers. They are configured to allow DDNS. We have got outside DNS servers that are servicing outside DNS queries. The XP clients point to the Internal DNS servers only and all of our XP clients are properly dynamically registering with DNS in the forward lookup zone. Can anyone tell me how to troubleshoot and find out what is going on inside the "Applying Computer Settings" which is taking so much long time? Thanks.
