sysprep computername

Windows 7 Pro x64 SP1. Trying to create image using WAIK and sysprep. Everything working fine except this: Want sysprep to prompt for computername during firstboot. Seems to work fine. Computer reboots and logs in as local admin. Checking and can confirm it is joined to the domain with computername given during firstboot. However, when logging on with a domain account i get this error: "the security database on the server does not have a computer account for this workstation trust" and when checking AD it is registered with a generic "WIN-g7ek58blabla" name instead of the given name. Here's the strange thing: When putting "<ComputerName>*</ComputerName>" in unattend.xml to make generic computername sysprep works just fine... no errors on login. Ideas?

Anything? Anyone?

Here's my unattend.xml and below the joindomain.vbs

Yes, there is a prompt for a name during firstboot. Tis is during the sysprep process. It auto logs in ad local admin, we do some other stuff, then reboot. When logging in it still complains about the issue. We will drop this and go for generic names, which does work. We have no time to error seek this issue, but thanks for the help anyway
