I've just updated an OES 1 SP2 box using rug and after the reboot, both iManager and NetStorage fail with Server Error 500.
Having tried to reconfigure iManager, I'm getting an other error stating that novlwww ownership to the nps folders can't be made. Having tried manually to chown I'm told that novlwww is an invalid user.

Can anyone shed any light as to what's going on here?

Thanks in advance.
