SharePoint Central Administration displayed just "Server error: http://go.microsoft.com/fwlink?LinkID=96177" error message on a SharePoint Farm.
After little research, Found Hot fixes are installed, but Products and Technologies wizard has not Run! After running "SharePoint Products and Technologies Configuration Wizard" everything turned up.
In case psconfig fails, try: stsadm –o upgrade –inplace -url <URL-Of-the-Web-app> -forceupgrade
If you still get issues after upgrade, You can follow the Microsoft KB: http://support.microsoft.com/kb/944267
