1) Remove then re-add TCP/IP and Dialup Networking. Remove any unused
network components, including NetBEUI.
2) Go to the Network control panel under TCP/IP and disable WINS. Add
DNS entries.
3) Under DUN connectoid, disable NetBEUI and IPX/SPX. Be sure Login to
Network is not checked. Make sure that Use Default Gateway on Remote Host
is checked.
These three steps cured 90% of the problems. We found a modem that
wasn't set for Login/Network, which brought it up to 95%.
4) If none of this helps, disable DNS under the control panel, and set
Server Assigned Domain Name Servers under the connectoid. This cleared up
the last of the complaints.

I just noticed something intersting re: Windoze 95 DUN. I have had several
customers experiencing the "could not negotiate compatible protocols"
error. We have a PM3 with the 33.6 cards running ComOS 3.7 and just added
an additional 16MB of memory. To accomodate our 3.1 and other customers,
we have a menu option setup to start PPP.
With 95, if the customer dials in with the "terminal window after dialing"
option turned on, logs in with their ID, password and sends the PPP option
from the menu, then tells windows to continue, we have nearly a 100%
success rate (I saw 1 failed attempt out of the 50 or so that I personally
tried and I think it was a modem compression hiccup) with connections. The
same customers, using the regular 95 authentication, seem to have less than
50% success rate, getting the "couldn't negotiate protocols" error a very
high percentage of the time.
Has this been mentioned here before? If not, does anyone have any ideas
why this would be happening?
Just thought I'd mention it. Thanks in advance for any insights given.
