Compatibility with user accounts ending with the dollar sign ($)

Applies to: Windows 7 ProfessionalWindows Server 2008 R2 Enterprise

Summary


Starting in Windows 7/2008R2, there are potential compatibility issues with using domain user accounts ending with the dollar sign ($) as a service account.  Managed service accounts are identified by ending in a dollar sign ($). The system may evaluate the account as a managed service account and block the change.

More Information


In the services console, if you enter a user account in a trusted domain that ends in the dollar sign ($), it will warn you that "The name provided is not a properly formed account name." This occurs because managed service accounts cannot be used in a trusted domain.
