The username or password is incorrect

Hi,

I have this MDT task sequence for setting up SCCM 2012 (I modified hydration kit for that: http://www.deploymentresearch.com/Research/tabid/62/EntryId/149/The-Hydration-Kit-for-System-Center-2012-R2-is-available-for-download.aspx)

Everything works/worked fine but now it doesn't want to allow the autologon, it says "Username or password incorrect".
Where is this autologon password stored? Note: I commented out the autologon in unattend.xml, have set the customsettings.ini, the customsettings.ini for specific server to correct logon info. Changed also the bootstrap.ini

DomainAdmin=Administrator    
DomainAdminDomain=ourdomain
DomainAdminPassword=ourdomainpassword

Please advise,
J.
