There is an issue with SCOM 2007 SP1 RC version. If you are using ADMP to monitor your Active Directory, and the DCs have non EN-US regional settings the value returned from * Last Bind (e.g. PDC last bind, DC last bind) Monitors is x1000. This means you will get many alerts, even though your infrastructure is in healthy state. If you run the AD General Response diagnostic task you see that the response time is way below thresholds. Thanks to Pontus (http://blopon.blogspot.com/) for posting this on newsgroups - thought I would share it here as well.

Sample Alerts affected:

"The AD Last Bind latency is above the configured threshold"

"The Op Master PDC Last Bind latency is above the configured threshold"

"The Op Master RID Master Last Bind latency is above the configured threshold"
