MED-V 1.0: Error: “Failed to fetch policy from the server”

After upgrading the MED-V 1.0 Server to either SP1 or SP2, the MED-V clients may get the following error:

“Failed to fetch policy from the server.”

You may also get this same error when trying to open up the MED-V Management console.

This can happen if the server version is newer than the client. For example, the server may be version 1.0.200 yet the clients may be 1.0.105.

Upgrading the clients to the same version (or later) than the server is the only solution to this problem.
