After performing in-place upgrade of the WEM Broker,  The WEM Admin console gives the following error when trying to connect to the WEM site:.

"Specified Infrastructure Server seems to be offline or have a wrong database configuration.  Please check configuration and try again"



Plus, when opening the Broker Service Configuration Console, all values may show as blank.

SOLUTION #1:  
Launch the Broker Service Configuration console on the WEM Broker and enter in the appropriate information to point to the correct WEM site.

***Review all the tabs to confirm all data is present, then click "Save Configuration".***




SOLUTION #2:

It may be necessary to create a brand new WEM Database do to unknown corruption on the database level.

SOLUTION #3: 
If DNS resolution is a problem, use the IP address of the Database Server to point to the Database inside of the Broker Server Configuration Console.  You may also choose to create a localhost entry on the WEM Broker with the Database Server name and IP address.
