I am a first-time CRM installer and I am running an installation in a restricted environment.
After many atempts, I cannot pass the system checks and the "Active Directory" check is always failing with the same message.
My setup:
The application is being installed on one server, SQL server and reporting services are on a second one.
CRM Server and SQL Server are on the same domain A, installing user U is on domain B.
There is an outgoing trust from domain A to domain B (not transitive).
User U has admin rights on both servers .
User U has read&write permissions to the OU created for CRM (just to this sub-tree, not to the entire AD)
User U is member of Local Administrators on those servers via a special group.
What I tried and did not help:
Adding Firewall exceptions to several TCP & UDP ports mentioned in the docs.
Turning firewall off.
Explicitely adding the user to Local Administrators, not just via a group.
Restarting the installation
Restarting the server
Running the installation "As an Administrator"
Could you please suggest me what else to try?
Is there any other relevant information I am missing?
