Ok, I noticed this. If i run the regedit hack before i join the domain. I get serious issues which force me to a new temporary username, machinename and workgroupname. Just like mentioned before in the topic. Thats what's troubling us.
Just join the domain before you aply the hack. and there are no problems. after you joined the domain succesfully, apply the hack so you can logon to your domain, etcetc.
, If you have to rejoin your domain cuz of some reason. Reverse the hack so the windows register is restored to original settings.
to restore original setting, turn the last 0 in the next line, into a 1
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\netlogon\parameters]
"RequireSignOrSeal"=dword:00000001
This solved allot of headaches for me. Hope it makes sence for some people.
