we have a very strange issue, we are using(windows 2016 for both):
1) RMS 2016
2) Sharepoint 2016 (September 2018 CU)
We were able to configure "Information Rights Management" after several tries.
The system initially kept showing the "Active Directory Rights Management Service Client MSIPC.DLL is present but could not be configured properly".
We finally were able to configure the intergration, but users were not able to use IRM.
In Central admin we keep getting the same error message: if we restart the farm(restart services and iisresest) and keep the administrative user logged (on the same RDP session that restarted the farm) then the integration seems to work ok. But, if we logoff from server and logon again the integration stop working.
With the permission and RmsAnalyzer-x64 seems everything is fine. It seems like an issue is with the user profile, but we cannot figure out what it could be.
Please help me with this. Many thanks in advance.
