I created 3 domains and 2 forests,
2. intranet.treyresearch.net (obvious child domain)
Upon making all dc's and creating the sites, I created a user in intranet.treyresearch.net and tried to logon with that user to the treyresearch.net domain...could not authenticate. I thought that child domains had an automatic two-way trust with the parent (confirmed with the forests and trusts console), yet I can not login...any reason? (the user does not exist in the parent domain does not exist there, though it shouldn't, the child domain should refer the user to the parent domain and based on the trust, should authenticate right?)
treyresearch.net has a two way relationship with nepeangroup.net, yet the user can not login to that domain? Why is that? What am I missing?
