SCOM Groups Dyanmic Members OU Recursive

Recently I went looking for a good way to add a group of servers to system center operations manager a bit more dynamically. I came across this article which I found very handy.

However, the last thing he says is..."Please note that this will only include machines in the OU specified, it you want to include computers from another OU you can simple add a “OR” expression."

Seems tedious at right? So I started looking for how to do recursive OU membership adds in SCOM. I found a bunch of stuff siting how to use custom LDAP queries, PowerShell, custom management packs. bleh...

Here's what I came up with....

1. Note the highest level OU for which you want to capture all sub-systems
2. Go to one of the systems in SCOM and view the properties in "Monitoring". One of the values will be "Organizational Unit" > Copy it
3. Create your Dynamic Members inclusion rule
4.  Select "Windows Computer" > Add

• Property = "Organizational Unit"
• Operator = "Matches Wildcard"
• Value = *< OU that you copied in step 2>

e.g.

*OU=XenApp-65,OU=Servers,DC=MYDOMAIN,DC=com

Works like a charm!
