Well, thanks butter, but this is for this is for Softice and not Visual Softice,

Softice is a single machine debugger that can also work on two machines remotely while Visual Softice is a two machine only debugger that can only work remotely (like windbg).

The problem I had was trying to make driver Work bench (the host part of DriverStudio) connect to Visual Softice which was installed on my vmware machine but since I never could connect I abandonned.
Especially since there is no reference to Visual SoftIce in the support site of Vmware (only to softice) (nor where there any useful information on the Compuware support page).
And I did read all the parts about remote debugging in the different manuals provided with Driver Studio.

SoftIce on the other hand always ran fine (except that while I never had anyu prob to debug an app I can't get it to debug my driver but that's on another thread), it was just that I wanted to use Visual Softice to get a nice interface full of jumpy windows and not a dull text interface

Regards,
