Hi
The "Distributed Link Tracking Client" controls file access accross networks. It sounds as if you may have problems with your network configuration, but the easiest thing to do, is to try and kill the service, and see if you lose functionality.
Start > Run > Type
Browse down to "Distributed Link Tracking Client" and double click.
You can either try setting this service to manual, or disable. To start with I would disable it.
On the General Tab - press "STOP" to stop the service, and then change startup type from Automatic to disabled. Apply and OK - Reboot.
See if this solves the immediate problem, and then continue to use your PC. If you find other problems, that may relate to networking, change the service back to "Automatic" and look for another solution.
The fact that you have formatted so many times, may indicate, that network services are causing errors using the "Distributed Link Tracking Client", that eminate from a hardware problem, such with your Network Card, but I can only speculate. If you need to back track, we'll have to look at other events, and find the true cause of the problem.
