sharepoint server error: http://go.microsoft.com/fwlink?LinkID=96177

Sometimes after wss re-installating when I try to browse sharepoint sites - I have gotten the error:  Server error: http://go.microsoft.com/fwlink?LinkID=96177


 
It might be fixed by running the following command:


 
stsadm –o upgrade –inplace [-url <http://mosswebsite URL>] -forceupgrade


Or simplier:


stsadm -o upgrade -forceupgrade -inplace
