I am having a problem with my samba 3 machine. It is a member of an NT 4 domain. A trust was recently formed between the AD server and the NT4 PDC, and resulted in the NT server rejecting the Samba servers credentials. When the trust is broken, the samba server works. How do I fix this problem. Several days after I had formed the trusted/trusting relationship between AD and NT domains, samba 3.0 had to be rebooted. The samba machine credentials were rejected by NT . When I broke the trusts with AD, all was fine between samba and the NT domain. Any thoughts on this transitive trust/machine authentication problem? Thanks, Jeff G
