Unable to complete DCPROMO. Password does not meet complexity?

Pardon me as I'm confused by this one myself. I've set up plenty of the Server 2008 AD's in test environments, and never had this error. Starts off just fine, install the ADDS role and then run DCPROMO. It's during this I get the error: "The local Administrator account becomes the domain Administrator account when you create a new domain. The new domain cannot be created because the local Administrator account password does not meet requirements. Currently, a password is not required for the local Administrator account. We recommend that you use the net user command -line tool with the /passwordreg:yes option to require a password for this account before you create the new domain; otherwise, a password will not be required for the domain Administrator account." What in the heck? I KNOW my password meets the requirements, but even if I change it to something very very complex it doesn't seem to care and throw's the same error during DCPROMO. I've even disabled complexity requirements in local security policy but this seems to have no effect. I'm at my wits end, any suggestions?
