Default timeout to zero results in "your connection has been rejected"

[Gabriel Green]

Hi all:

I am trying to adjust registry keys on remote machines so that instead of
the idiotic 180 second timeout I imaged them with, I would prefer to make it
zero.

However -

When I set it to zero, and tried to get back in, it results in an immediate
refusal of the connection.

What registry values should I adjust so that:

There is no timeout or user prompt for approval - the connection is
immediate (whether view-only or interact.)

Thanks -
Gabe
