Consider the following scenario:

  • You have a computer that is running Windows Vista or Windows Server 2008 in a domain.
  • You configure a scheduled task on the computer.
  • You try to change the running user context from the default user account to another account in the domain.

In this scenario, you receive the following error message:

An error has occurred for task TaskName. Error message: The specified account name is not valid
This problem occurs if the NetBIOS domain name is not the default name.

Note: By default, a NetBIOS name is the leftmost part of the DNS domain name. For example, if the DNS name is “contoso.com,” the NetBIOS domain name is “CONTOSO.” However, an administrator may arbitrarily choose any valid NetBIOS name.
