POLICY MANAGER-(X-30): Server base license certificate used to get a license for the server servername is not valid.

Source: POLIMGR.NLM

Explanation: The digital signature on the server base license certificate is corrupted or invalid.

Possible Cause: SERVER.EXE does not match the license certificate for a server base license. You might have a beta version of SERVER.EXE but a shipping version of the license certificate.

Action: Install the correct SERVER.EXE file or version or the correct license certificate.
