Master Client Database reports version 0.0.0 or is otherwise corrupt

The Master client database may return an error message or fail catastrophically reporting version 0.0.0..

This is old information. The best fix is to upgrade MonTel to use MSDE or SQL Server. The MonTel upgrade is free to clients on current maintenance. Not only will this update reduce database corruption to practically nil, because MonTel was originally written with SQL in mind, updates will be 10 to 20 times (or more) faster than versions using the Jet engine Master Client Database.

Unless this is while it is being created for the first time it may indicates database corruption, which will need to be repaired. Quite often though it indicates some network changes, or changes on the users computer - concerning network access or the correct mapping of drivers or paths.

To determine if it corruption you will need to eliminate the other causes:

• Check that the problem occurs on more than one users computer. If is occurs only on one users computer, it may be caused by the path problems below, or by a corrupted local database. See TROUBLE SHOOT: Various errors and problems connecting to the client database that occur on only one users computer.
• Check that the full path, including the drive, from the PABX.INI file [ClientDB] section ClientDatabaseLocation, and the Client32DatabaseName really exists and is "visible" on the users computer.
• Make sure that all users have full (read and write) access to the ClientDatabaseLocation directory or folder.

If all these check out OK then you will need to recover the corrupted database. You may either restore it from backup, or preferentially attempt to repair it. For details on how to repair it see TROUBLE SHOOT: How to repair a corrupted Master Client Database.
