Access denied when verifying a trust between a 2000 and 2003 domain

OK, here is the problem. I am trying to create a two-way trust between a 2000 domain and a 2003 domain. We have many other trusts and domains so this is nothing new. I creat the trust from the 2003 server and have it create both. I can verify from the 2003 domain but when I verify from the 2000 domain I receive an Active Directory Access Denied error. I have other 2000 domains that trust the 2003 domain that work fine. I have checked the DNS lookup zones and everything seems to be correct. part of it must be working because I can ping and browse the 2000 domain from the 2003 however I cannot browse the 2003 domain from the 2000. Any ideas???

Thanks,
Larry

can you check the following registry keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters

on both the windows 2000 and win 2003 Dc's ?
also can you check the Lmcompatibilitylevel under the LSA key in the registry .
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA

When I try and verify the trust from the Windows 2000 domain and enter the user name and password for the 2003 domain I receive an Active Directory "Access Denied" error. That is all I receive.

Thanks,

The LM compatibility os as follows:
2000server 0
2003server 2

I have attached copies of the other registry entries.

The 2003 server does have other successful trusts with 2000 domains. as does the 2000 domain

Thanks for the help!

Figured it out after comparing the registry entries with different machines. Needed to enable security signature on the 2000 machine. Thanks!
