Hotfix for RID Pool Depletion! KB 261869

A few months back I thought I was going to write a blog post about how to look for RID Pool depletion in environments. Then I got side tracked with something (probably finding out why Mad Men isn't on yet) and Ned Pyle wrote an awesome post that would of put anything I would have wrote to shame anyways.

If you haven't read it I recommend you stop what you are doing and read it! So now you see how important that is to manage. There is a new KB Hotfix I recommended highly reading through it and then going through the proper testing channels for your environment. 

MS KB 2618669

Some key highlights directly from the KB

Cause:

In certain rare circumstances, a ___domain controller may issue recurring requests for RIDs from the global RID pool every 30 seconds.

If repetitive requests for RID pool updates are unchecked for a significant time, the global RID pool may experience too much consumption, and in extreme cases, may experience complete exhaustion of the global RID pool.

Resolution:

To prevent too much consumption of the global RID pool, we recommend that you take the following actions:

  • Install this hotfix on all existing Windows Server 2008 R2 ___domain controllers.
  • Integrate the update into the Windows Server 2008 R2 installation media. It guarantees that future ___domain controllers also have this update.

Happy testing!
