Thank you for your efforts! Keep in mind however - if you can't figure it out, then it's not a big deal... I am only making experimental installations now anyway, and a process gone wrong here and there is just a learning point for me that will help me make better and more "thought of" customizations in the future. I did however discover that the following file(s) and registry entries need to be present for the Second Logon service (this is just reference for anyone who is experiencing the same problem): Secondary Logon DLL - seclogon.dll (in WINDOWS/system32 folder) Secondary Logon registry entries - Services entry: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\seclogon] "Description"="Enables starting processes under alternate credentials.
