Hello, I a Dynamic Inclusion Rule for the membership of a SCOM Group: ( Object is Windows Computer AND ( NetBIOS Computer Name Matches regular expression (?i:^VODCC*|?i:^VOPCC*)) ) AND True ) Why do I catch a machine named VODCACS1? Isd it the ^ which display any order? Also itb shows an error Date: 4/25/2011 3:38:30 PM Application: System Center Operations Manager 2007 R2 Application Version: 6.1.7221.0 Severity: Error Message: Microsoft.EnterpriseManagement.Common.UnknownServiceException: The service threw an unknown exception.

Hi Dom, Have you been renaming this group or changing it to reflect the other naming convention of BOPCC to VOPCC? Try to create a new group with different name and such and see if that one also gives you this error.Bob Cornelissen - BICTT (My BICTT Blog)

I think the regex is incorrect. * = any repeat of previous char (any number of C in your regex). "." is a wildcard (.* any number of repeats). The match would only be for VODCC and VOPCC with any repeats of C. Just try to be a specific as possible with regex. I'd write it like this: ^VO(D|P)CC.* I'm not sure what ?i: means (case insensitive?). You might need to start with ^ Rob Korving http://jama00.wordpress.com/
