Adding computer to AD group

[Kevin79]

I'm trying to automatically add computers to AD groups during OSD. I followed Jorgen's tutorial (http://ccmexec.com/2010/08/adding-computer-to-ad-groups-during-deployment/) but can't get it working. The TS keeps failing and I get " <![LOG[::LogonUser(sUserAccountName, sUserDomainName, sUserPassword, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, &hUserToken), HRESULT=8007052e" in my log file. How do I get this to work? Should I use a different method to add computers to groups?

At what point in the task sequence are you performing this action?

Towards the end, after I install software but before I install all the updates.
