QuickBooks depends on its program files to run smoothly and perform its 
tasks efficiently. The transaction log file stores transactions of the 
software, whereas the network descriptor file helps it to set up a multi-

QuickBooks leads to a malfunction in the Database Server Manager. You 
can resolve the issue by renaming the files and scanning them in the 
DBSM. Use these steps-
1. Open your QB folder using a file explorer to find .tlg & .nd files inside.
2. Right-click the files individually and tap the Rename option.
3. Type ‘.old’ after the extension in both the file names and save them.
4. Try running DBSM, and if it opens, go to the Scan Folders tab and 
select the folder where you renamed the files.
5. Hit Start Scan and wait until the scan completes.
If DBSM fails to run while scanning the folder contents, use the next 
solution.
Solution 2- Restart the DBSM service on 
your PC

glitches that can occur due to factors on your system other than 
QuickBooks. These issues get automatically fixed when you reboot your
