The RM Unify AD Sync service stops immediately after starting.

The system log may report the following error for the service:

"Service cannot be started. System.InvalidOperationException: Unable to generate a temporary class (result=1).
error CS2001: Source file 'C:\WINDOWS\TEMP\filename.cs' could not be found", where C:\WINDOWS\TEMP\filename varies depending on your installation location.

There are two possible causes of this issue:

1. If the system log reports the error noted in the Symptoms section above:
   The identitysyncservice user configured to log on as the RM Unify AD Sync service has insufficient permissions to the folder specified e.g C:\Program Files (x86)\RM\RM Unify AD Sync\LogFiles. 
   
2. If the system log does not report an error, then it may be that the identitysyncservice user has insufficient permissions to the C:\Program Files (x86)\RM\RM Unify AD Sync folder.

1. Assign the identitysyncservice user the following permissions on the folder specified in the error message:
   • Read & execute.
   • List folder contents.
   • Read.
2. Restart the RM Unify AD Sync service.

Assign Modify permissions on the C:\Program Files(x86)\RM\RM Unify AD Sync Service folder for the identitysyncservice user.
