I've got a development box, old dev box, windows 2000, sql 2000, that runs a restore script daily.   This Restore script is a vbs file, it restores a file ftp'd from the production box.  It has run for many years with no issues, now every 3-4 days it hangs and runs forever.  So far the only solution has been to reboot the box.

I've dug around a bit and found many instances (10, 15, sometimes 20+) of dw20.exe running in the process / task list.

This is listed as the windows error reporting tool.  Not sure what is erroring or being reported on, but since this server is shared with devlopers who have local admin access to the server, i'd bet someone did something that than began causing this error...either configuration changes or installed some software, difficult to determine.

So far I've only found a two easy solutions, put the box on a daily reboot, or disable the windows error reporting tool.

I'm going to try and disable the tool and see what happens:
