"An external error has occurred" error when you change the user rights of an account in Local Security Policy in Windows Server 2008 R2

Symptoms

Consider the following scenario:

  • You install Internet Information Services (IIS) 7.5 on a computer that is running Windows Server 2008 R2.

  • You create a user account that contains a virtual account that has a domain prefix of "IIS AppPool\".

  • You try to change the user rights of the account in Local Security Policy.

In this scenario, you receive the following error message:

An external error has occurred. Failed to save Local Policy Database

If you go back into Local Security Policy to check the user right, you find that the Classic .NET AppPool and DefaultAppPool groups disappeared from the user right.
