JSI Tip 3765. DCPromo fails with 'Overlapped I/O Operation Is in Progress'?

When you attempt to promote a member server to a domain controller, you receive:

Overlapped I/O operation is in progress.

If you have a 3rd party real-time backup product installed on the member server, it caninterfere with with the Active Directory Installation Wizard during the creation of the SYSVOL folder.

To resolve the problem, remove the 3rd party software, restart the server, and run DCPromo.

If you look at the Dcpromo.log, it would have entries similar to:
