在Windows Server 2008 R2 DC中存在一个问题，在极少数情况下，Windows Server 2008 R2 DC 每隔 30 秒向全局RID池申请RID，可以想象，每隔30秒就做一次申请，最后可能导致整个域的RID耗尽。 

Under certain rare circumstances, Windows Server 2008 R2 domain controllers unexpectedly consume a large amount of RID resources. This behavior exhausts the global RID pool. When this issue occurs, you experience one or more of the following issues:

• RIDs in the global RID pool are continually being consumed over time.
• The number of RIDs that are consumed in the global RID pool is is greater than expected, considering the number of security principals that are intentionally created during the lifetime of the domain.
• The DCDIAG RID Manager test indicates that a search for the RidSetReferences attribute fails. Additionally, you receive the following error message:

  Starting test: RidManager 

  Warning: attribute rIdSetReferences missing from 
  CN=name,OU=Domain Controllers,DC=name,DC=name,DC=name,DC=name 
  Could not get Rid set Reference :failed with 8481: 
  The search failed to retrieve attributes from the database. 
  ......................... name failed test RidManagerThis hotfix enables the ability to detect and prevent this behavior on Windows Server 2008 R2-based domain controllers.
