System Center Operations Manager 2007 considers an object that contains a wildcard string to be a member of the group when a group uses a wildcard inclusion formula that targets a principal name

When you create a group that uses a wildcard inclusion formula that targets a principal name in System Center Operations Manager 2007, System Center Operations Manager considers a computer object that contains the wildcard string in the principal name to be a member of the group. For example, you may use the following dynamic group inclusion formula:This group includes the following members:

• Serveris01.domain.com
• isserver01.domain.com

This problem occurs because System Center Operations Manager translates the wildcard syntax for the regular expression as follows:This expression matches any string that conatins at least one O. Additionally, this expression is case-sensitive.

A case-insensitive regular expression resembles the following:

To work around this problem, select the Matches Regular Expression match policy in the Computer Name field so that you use ^[Oo] instead of O*.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
