Hello,
I've been having issues with an Sql connection for some time, The server has been replaced, 2003 R2 to 2008 R2, the issues occured before and after the server was migrated to new hardware. once or twice an hour a users connection is dropped,
causing table locks, and other errors.
All network switches have also been replaced, network cabling betwwen the desktop \ server and switch have also been tested. The Sql Server was rebuilt to 2008 R2 ( DC) with SQL 2008 SP2, I dont understand how the problem can still exist with all of the changes made, new server, Clean OS, Clean install of SQL, New Switches.
Al users have local administrator rights on there Windows 7 desktops.
Users are connected using a DSN connection to the DB, the connection is dropping with the following errors:
1. [Microsoft][ODBC SQL Server Driver]Communication Link Failure.
2. The Table CRIMESLOCK could not be locked. it has probably been locked by another users.....
3. Event ID: 1000 Application Error.

Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Facility

The error value is listed in the Additional Data section.
User Action
1. Open the file again. This situation might be a temporary problem that corrects itself when the program runs again.
2. If the file still cannot be accessed and
- It is on the network, your network administrator should verify that there is not a problem with the network and that the server can be contacted.
- It is on a removable disk, for example, a floppy disk or CD-ROM, verify that the disk is fully inserted into the computer.
3. Check and repair the file system by running CHKDSK. To run CHKDSK, click Start, click Run, type CMD, and then click OK. At the command prompt, type CHKDSK /F, and then press ENTER.
4. If the problem persists, restore the file from a backup copy.
5. Determine whether other files on the same disk can be opened. If not, the disk might be damaged. If it is a hard disk, contact your administrator or computer hardware vendor for further assistance.
