Hi, Windows Server Standard, 2008 R2, Service Pack 2, 64bit. I have some user defined Data Collector Sets and I'd like to schedule them. The account is 'System', but they are not running at the scheduled times. I've tried entering my creds in the run as box, but I get an error message saying When attempting to create the Data Collector Set the following system error occured: A specified logon session does not exist. It may already have been terminate. The set cannot be created, of if I try to change this, the set is gone when the node is refreshed. mmc also crashes from time to time. Any ideas on what to do here? The new logging looks nice, but it's proving to be unusable so far.
