Question:
Why do I get a license error suddenly in my load-balanced environment?
Answer:
In order for the load balanced license to work, the master site needs to be running. When visiting the master site, it will write data in the database table TblMasterSlave, and the slave(s) will read from this table to confirm that it is “their” master.
The license error can occur if the master site has been down for a long time. It can also occur if you have moved the database and changed the connection string.
To solve this, remove all content in TblMasterSlave (there should only be one row), then restart the master and surf against it. Then do the same against the slave(s).
Error message:
"This slave site has no master licence information"
Or
“This slave site failed when validating master license information”
