>I have some VFP COM objects running in memory. In the task manager, I can see them in the Process tab. However, I can't remove them from memory. Those objects seems to be used by something. How can I kill them without having to reboot?

Are they being used by IIS? If so, you can start and stop IIS. With Win2K/IIS5, you can use:

IISRESET /RESTART

For earlier versions, you can use a batch file that kills and restarts IIS with NET STOP.../NET START.
