mwolterTry this: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList\#vAgentConfiguration.credentialName# and use a reg_dword value of 0. Now if this is a 64 bit machine you will need to use k2 to set a the value with the new registry setting for 64 bit machines.
mwolterLarry, this does work on windows vista. Not sure about Win 7 though. Make sure you "use credential" before trying to set the registry value. I also noticed that there is a space in "userlist" where there should be.
