1. Can the machines run a dos window manually? Can you open a dos window, execute the command, and then exit the msdos window without the system freezing?
2. Is it always and only the same program or command being run inside the dos window?
3. Was anything changed on the workstations? Service pack installed, patch installed, new graphics, drivers, etc?
4. Can you post your run command?

VFP is obviously frozen as well but what's really weird is that WIN2k is sort of frozen as well. You can still click the task bar and move the mouse around but you can't run any new programs and if you try to kill the DOS window or the VFP program (assuming the task manager was up , because if it wasn't you cannot bring it up) the whole computer freezes completely.
