asked on windows authentication and sbs console error on SBS 2008
Hello,
Since a week ago our SBS 2008 is not functioning properly.Users have reported that they cannot print through any of the printers installed on SBS 2008.
When I tried to access the server I could not log on to the server as administrator because of following error:
“Windows SBS 2008 Console has stopped working” and Windows Authentication “an unauthorized change has been made to windows”.
After a restart I could log on and I have reinstalled SBS 2008 console. For a day everything was ok. After a day same problems came back and there were errors in event log viewer:
Microsoft-Windows-Security
I tried to check the license validation using slmgr.vbs script but it was not possible to run the script. In CMD I have typed slmgr.vbs /? and got Windows Authentication “an unauthorized change has been made to windows” error again.
![windows activation]()
![windows script host windows]()
When running that script a lot of functionality of the servers gets blocked. Also the printers, control panel, windows update are not functioning till you restart a server again.
It seems to me that slmgr.vbs script is corrupt. I have seen on forums that more people are having this problem but no solution.
sfc \scannow did not find any problems. The server is installed 2 years ago and has a valid licence.
Does anyone know how to fix this problem?
Your help is highly appreciated.
Thank you.
