I am having the issue described in the below link. The only reason I know that it is caused by Symantec Endpoint Protection, is due to the fact that after uninstalling it, the script errors disappear. I have added all the exceptions recommended by Microsoft to no avail. Symantec support has not been helpful. Has anyone else encountered this issue? How were you able to resolve it? Thanks! http://support.microsoft.com/default.aspx?scid=kb;en-us;967503&sd=rss&spid=12584

OK, so on SEP you should disable monitoring of following things: Processes: monitoringhost.exe, healthservice.exe, cscript.exe Folder: C:\Program Files\System Center Operations Manager 2007 R.E.M. - YEAH!
