I created a domain trust between my company (Company A) and the parent company (Company B). Employees at the parent company can logon to company A domain but employees at company A can't logon to company B domain. They get a message stating that company B domain is not available.
Domain trust type: Forest, two-way, transitive
Domain Controller: Server 2008 R2 on both domains
The incoming trust and outgoing trust validation is successful on both DC's
No errors showing in DNS. I've created forward and reverse secondary lookup zones for both domains on both domain controllers.
I enabled transfer zones to any server on both DNS servers.
I can ping Company B DC and they can ping my DC using IP address.
I can also ping domainB.local and they can ping domainA.local successfully.
We can also ping successfully using the host name as long as we include the FQDN in the ping command (DomainA.xyz.local).
I created another domain trust with another sister company (Company C) with the same exact description specified for company B and employees at company A can logon to company c domain and vice versa.
Any help will be greatly appreciated.
P.S the admin in company B created a test account for me. When I try to use the test account to logon to company B domain, it tells me that I need to change my password. When I fill in my new password, I get a message saying domain B is not available.
Thanks!
