debugging with interdev 6.0 works only one time

[hucky]

Hello everybody,

i installed Win2k with ServicePack 2 on my new machine, afterwards I installed IIS (everything) and later VisualStudio 6.0.

Now following problem occurs while debugging any ASP with InterDev:
For the 1st time I start the InterDev-Debugger everything works fine. It stops at breakpoints and bugs. But when I start it again the debugger ignores breakpoints and bugs and error messages are printed in the browser.
If I activate the Debug options in the IIS manually debugging works, only the automatical debugging from Interdev works only one time.
Sometimes I got an error message which says something like: "remote procedure calling has failed" (this is only a re-translation of the error message I receive in German).

I don't know what to do.

Thanks to everybody
Hucky
