SYMPTOMS
When you run the Active Directory Installation Wizard (Dcpromo.exe), if you promote a member server to a domain controller, the operation fails, and you may receive the following error message:

Overlapped I/O operation is in progress.



CAUSE
This problem can occur if a third-party, real-time backup product is installed on the server. The third-party service interferes with the Active Directory Installation Wizard when it recreates the SYSVOL folder.



RESOLUTION
To resolve this problem, remove the third-party backup software, restart the server, and then run the Active Directory Installation Wizard again.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
