Hi there,
Are both the servers on the same domain ?
All domain trust relationships have only two domains in the relationship: the trusting domain and the trusted domain. A domain trust relationship is characterized by whether it is:
One-way
Two-way
Transitive
Nontransitive
For Setting up Trust between different domain (companies) follow this https://social.technet.microsoft.com/Forums/windowsserver/en-US/57d49257-f3d2-4b83-ac5a-8836944a6999/setting-up-trust-between-different-domain-companies?forum=winserverDS
