Yup this is a complex one or rather I've been working on it for ages and can't find the soloution. Kit as follows:

Dell Latitude L400 laptop Running NT4+SP6A
Psion Gold Card with ISDN upgrade installed and recognised.

Ok I have a ghost image of an old install of NT4 with sp6a etc and the gold card works fine in PSTN mode and ISDN mode (when using ipconfig /all system reports same Gateway as it's own IP which is normal I'm told) However on this old build routing etc works fine I can browse the net etc and ping to my hearts content (it's a RAS connection to a corporate LAN).

Now I have created a new build with NT4+SP6a and installed and setup the Gold card (tried with and without ISDN part). The bindings to the card etc seem excatly the same as the old build. However some times the connection fails to complete complaing of a PPP timeout waiting for a response from the server. When it does connect I get no routing what so ever can't even ping IP addresses on the local lan let alone DNS names.

Anyone got any ideas???

did you set the software up with the card connected to the line?

Check the dialup connection settings - doesn't sound like a binding problem to me.

If you can compare new and old, that would help.

Not when doing the PSTN part (which comes first obviously) but wheh install the ISDN upgrade you are require to plug the ISDN dongle into the card (goes inplace of the PSTN lead). But on later attempts of installing the OS and then Card etc I have not bothered with the ISDN part as I can't even get the PSTN part to work.

I can compare new and old (only by ghosting back the image which takes 15 mins or so) but I have checked and dial-up settings I can't see anything different. But I will check again now.

I'm fairly sure that having Wan wrappers is normal for an ISDN card is it not? (even before the ISDN) drivers are installed.

Hmm, only other thing I can think of is that it IS bindings related and you have NetBeui above IP, and it's rejecting because of that.

I take it the modem dials OK, do you get as far as "Verifying Username and Password"?

Oh yes it even connects and get's authenticated(SecurID) just no routing to be had at all.

I don't even have Netbeui installed...

Are you connecting to a modem hanging out the back of a server or is it a dedicated RAS box?

Are you using fixed IP or relying on DHCP? Is the server running WINS as well as DNS?
Just trying to get an idea of the setup before I pass on my thoughts.

DHCP + WINS + DNS (Large corporate LAN)
I'm just going over to another build to show some one else the problem to see if they can shed some light on it.

OK, have you made sure under the IP settings that "Use default gateway on remote network" is flagged (ie enabled)?

Otherwise, you won't be able to connect to anything, despite making the connection.

OK, so you say it connects but can't route anywhere. When you do an ipconfig, I assume you get 0.0.0.0 ?

Just another thought: did you UNCHECK "Enable LCP extensions" in the server part of the dialup connection?

Checking for 0.0.0.0 would be my next question too Greg.

Hi guys thanks for you posts - Have LCP over PPP enabled on the old build as well as the new - works on the old. Have disabled and tried on the new build and still no joy.

Oh and yes I get an IP address - which is the same as the default gateway but I'm told that this is normal???

it seems that I get routing for about 2-3 seconds after connection and then it drops out???? i.e. no routing.

Darn. My money was on the LCP.

Is it the authentication method you're using (CHAP, MS-CHAP)? Sorry, but my knowledge of NT4 RAS is a bit rusty, as you can probably tell.

With a Smartcard you're going to need EAS somewhere down the line.

hmm, things have moved on a bit:

If I connect and touch nothing other than pinging a server by it's name from dos prompt using minus t I can get a reasonable connection and return i.e. 90% but a soon as I try and access a resource on that server (drive/share) the ping request times out and never recovers...

Authentication method correct then?
