I know that they are no longer supported - but have any of you experienced I/O freezes/hangs of Windows Server 2008 R2 when installing the Sysmon64 service? We did that yesterday as part of a 3rd party SIEM suite and all the 2008-R2s were effectively "killed" by that, it takes like forever to log-on und do anything, you may not even be able to invoke run-as from Task Manager and so on. Ressource Monitor shows low CPU and RAM but all I/O-related tabs are blank - no disk I/O, no network I/O shown - like the I/O subsys is completely hung/frozen.
On those systems were I was able to get to the proper CMD and "issued sysmon64 -u force" everything went back to normal.
Now I also wonder what's in 13.02 that has been published yesterday - no release notes to be found yet?
