Answer 1

Hi @pacem , welcome to Q&A forum!

What version of SharePoint are you using?

You could first check your accounts, some users in a similar situation solved the problem with correct accounts.

See the related two posts:
Getting Error The trust relationship between the primary domain
The trust relationship between the primary domain and the trusted domain failed when Publishing feature is enabled

===========================================================

And as mentioned in the thread

There are 3 possible causes for your issue in my mind:

• The trust relationship between primary domain was broken.
• The firewall blocked the connections used for establish trust relationship.
• Configuration caches was corrupted.

For number 1, please verify the trust (http://technet.microsoft.com/en-us/library/cc737447.aspx) and try to recreate the trust (http://technet.microsoft.com/en-us/library/cc758857.aspx)

For number 2, please follow the steps:

• If possible, temporarily stop the firewall in both servers to verify whether this is the cause of the issue.
• If this the cause of the issue, Open ports 1025 and 1026 used to RPC session for SharePoint. see KB899148 (http://support.microsoft.com/kb/899148) for more information.
• If open ports 1025 and 1026 cannot resolve the issue, please use Network Monitor tool to do further troubleshooting.

For number 3, please follow the steps to refresh the configuration cache.

• Open Start > Run and type %allusersprofile% to open all users’ profile folder.
• Navigate to Microsoft\SharePoint\Config[GUID] folder.
• You should see a cache.ini file and lots of XML document. Delete all the XML document.
• Edit cache.ini, change the number to Save and close it.
• Restart Windows SharePoint Services Timer in Services
