I have 2 domains that have a Trust Relationship between the two.(Domain_1 and Domain_2) I upgraded to Service Pack 6A and the Trust Relationship starting acting a little strange. I can access the Domain_2 from Domain_1 no problems. Map network drives copy files etc.... From Domain_2 I can view the computers on the network from Network Neighbor, can map a drive from Network Neighbor but, can not map from the Windows Explorer. When I am at a Domain_2 machine if I try to access a computer in Domain_1 I get a error message stating "Access Denied". No problem from Domain_1 to Domain_2. I have checked the router configuartions, check gateway address configurations, have even un-installed SP6A and re-installed SP4. No luck. If you try to ping from a Domain_2 machine to a Domain_1 machine, no luck. Can't even get FTP or Telent to work. Either direction. However if you access the router you can ping all machines.

Im thinking name resolution issue. When you map a drive to another machine it tries to resolve the name. If you can resolve the name, but get access denied then it prob is a permission thing. Did it work before the SP6A upgrade?

If your not running it place a WINS server in each domain and configure a PUSH/PULL configurations. Then try the same tests. This might help.

Good Luck

Use Domainmon.exe from the RSK to check the status of your trusts. Im assuming you have a two way trust, if not, you need a two way trust to make this work. At most you may have to delete the trust in the direction of the resouce your trying to use and cant and re-establish it. This is common in trusts and exatly why everyone wants to run from them.

Hi,

check you Trust with NLTEST (Reskit) or with DOMMON (ResKit), your Trust seems to be cracked.

Usually when you install a new service pack, things can get a little bit wacky! Did you install the service pack on only one of the domain controllers or all of them? In either case, I would break the trusts and re-establish them
