Log on very slow

on
We have three domain sarvers A, B and C.
A is 2000 advanced server
B is Nt 4.0
C is 2000 server
There is a trust relationship between A and B and also B and C. There is no one between A and C
Active Directory is running in both 2000 servers.

Log on from 98 or Nt Workgroup Machines is fast to any af the domains.

Case I
When XP Pro machines are configured to domain C (2000 Server) they can log on fast to domains B and C (and not to A because there is not a trust relationship)

Case II
When XP Pro machines have been configured to the B domain they can log on fast to domains A and B, AND VERY SLOW to domain C.

How can we speed access to domain C in case II?

BONUS INFO:

Speed up your browsing of Windows 2000 & XP machines AND Speed up viewing shared files across a network


Here's a great tip to speed up your browsing of Windows 2000 & XP machines.
Its actually a fix to a bug installed as default in Windows 2000 that scans shared files for Scheduled Tasks.
And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because
Windows 2000 is using the extra time to search the remote computer for any Scheduled Tasks.
Note that though the fix is originally intended for only those affected, Windows 2000 users will experience
that the actual browsing speed of both the Internet & Windows Explorers improve significantly after applying it
since it doesn't search for Scheduled Tasks anymore.
Here's how :

Open up the Registry and go to :

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Explorer/RemoteComputer/NameSpace

Under that branch, select the key :{D6277990-4C6A-11CF-8D87-00AA0060F5BF} and delete it.

This is key that instructs Windows to search for Scheduled Tasks.
If you like you may want to export the exact branch so that you can restore the key if necessary.

This fix is so effective that it doesn't require a reboot and you can almost immediately determine yourself how much it speeds up your browsing processes.
