Various errors and problems connecting to the client database that occur on only one users computer (Local DB Corruption)

On rare occasions the MonTel Client may fail to start or hang, possibly reporting various errors in trying to connect to either the Local Client Database or the Master Client database.

If these problems are occurring on only one (or two) users computers, while others have no problems accessing the Master Client Database, it indicates that the problem is most likely to be on the local computer, and is probably corruption of the local client database.

See also: TROUBLE SHOOT: Errors such as Error 91, 3265, 3078 and others on only one or a few of the computers running MonTel.

This may be caused by:

• Insufficient hard drive space.
• A very badly fragmented hard drive.
• The computer being shutdown in-appropriately (by the user or a power black out).
• Some other software of hardware problem, including a computer virus or hardware failure.
• Issues related to Windows or DLL compatibility, other applications and bugs in the Microsoft Jet engine.

The good news is that problems with Local Client Database corruption are very easily fixed.

This is because the Local Client Database stores only links, and not data, to the Master Client Database.

Make sure that the MonTel client is not running, and then simply delete the existing Local Client Database, that is the file generally named in the PABX.INI file [ClientDB] section identified by the LocalDatabaseLocation folder and named by Local32DatabaseName. Typically this is "C:\MONTEL\LOCAL" and "CLIENT32". On some systems this may vary as the users or the system administrator, may have chosen a different location for the Local Client Database.

You can also check the MONTEL.INI file found in the Windows directory, usually C:\WINDOWS on Win9x/me systems, and C:\WINNT on WinNT/2000 systems, for the ApplicationDatabase for a more definitive path (again typically C:\MONTEL\LOCAL\).

Once deleted, restart the MonTel client, and the local client database will automatically be re-created, in a few seconds.

If the creation process loops there may be another issue, which is covered in the topic TROUBLE SHOOT: Local Client Database fails to create or creation loops.

Other causes:

If it comes down to issues related to Windows or DLL compatibility, other applications and bugs in the Microsoft Jet engine, then these will be machine specific and fall out side issues that MonTel can control.

This article on the MS Web site covers some of these and provides a good methodology for solving the problems: ID: Q148424 http://support.microsoft.com/support/kb/articles/Q148/4/24.ASP
