You miss my point. The question was what Microsoft could do to fix all these RPC issues. The answer is to stop using it, which was going to take time..     -------------------------------------------------------------- Roger D.

On the other hand, I have plenty of Unix boxes running with RPC disabled and they run fine.   Let's remember RPC's major functionality can be replaced, but that's at the expense of more complex application design.   Roger -------------------------------------------------------------- Roger D.
