Over night our companyweb page stopped working. As far as I know the only thing that was being done by the server was a backup to a USB drive. This is the error that we get when we try browse to the companyweb:
Could not load type Microsoft.SharePoint.Libra
ry.SPReque
stInternal
Class from assembly Microsoft.SharePoint.Libra
ry, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e
9429c because it attempts to implement a class as an interface.
What would have caused this and what can I do to rectivfy it?
Thanks
