Description:

The schema version (3.0.149.0) of the database WSS_Content_123 on TFSDataTier is not consistent with the expected database schema version (3.0.151.0) on TFSAppTier.  Connections to this database from this server have been blocked to avoid data loss.  Upgrade the web front end or the content database to ensure that these versions match.
