Hello, I have a test lab with all Server 2003 DCs. Both domain's functional levels are Win2000 native mode. The two way trust is in place and validated. I am able to log into member servers and desktops in either domain (log on to drop down displays both domains). From either domain I am unable to Delegate Control, or connect to another domain in AD. I can ping the PDC for both domains from the trusting domain. They are all VMs and I have tried booting in specific order, one PDC then the other. I also tried booting up one PDC, waited 15 minutes and booted the other. Please help!
