Hi Mark... GC seems to be proper in RUS properties...one more thing i would like to add here as i increased the logging level on LDAP so i am getting Error Events with ID 8270...with error code [34} ...i am not able to fine anything related to [34] on support site on microsoft. DNS seems to be ok...name resolution is also working fine accross the root & child domains. any clues..??? Regards, Vijay Dogra.
