Product / patch installation or server upgrade required.
One or more servers is not responding.
Warning: The farm servers do not currently have the same product and patch level as each other. This page only shows the database status as related to the product and patch level for the server that served this page, and may not be correct for other farm servers until they have the same set of required products and patches installed.
- psconfig won't run because it says service pack 1 is missing from one server when it's not. It has been installed on all servers and if I try to install it again it says there is nothing to be updated.
- all servers show there are no available updates.
It's the strangest issue and I really don't want to rebuild the farm.
