Server 2003 DC running Sage Line 50 v11 (yes I know) on RDS.
At random intervals when Sage being used (not the same operations) the server freezes for the user. Other logons in progress are delayed, but other sessions still have mouse control etc.
Nothing appears in the logs except a couple of hundred Audit Success event 565 for the duration of the event. Events last up to 2 minutes.
The 565 events are the first common factor I've found.
I've checked the disk, that's fine. DCDIAG passes. Just puzzling.
Any ideas?
