S&D 3 "Failed to connect to drivers storage"

I have put my drivers in a network share that is hosted on the Acronis server (SBS 2003, domain controller) and have tried using both DOMAIN\Administrator & Password/Administrator & Password on the driver storage section of the deployment template. I get the same message either way.

I can connect to this share from a non-domain computer without issue - \\netbios\share and enter Administrator & Password when prompted.

I am using the domain admin account so permissions are definitely not a problem.

Any help would be appreciated. I am not having much luck with this product so far

 

Not certain yet, but initial testing indicates that if hosting shares on a domain controller the policy for the DC container in AD has to be changed so that Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Microsoft Network Server: Digitally Sign Communications (Always) = Disabled.

The default is Enabled.
