Help! I have a Dial-Up-Networking problem I need help resolving.......

[Slap]

OK! I am at work and all our PC's are on an NT network. I am having problems with DUN on one of them. I have setup DUN to dial out to a server. The problem is that when it makes the connection to the server, it drops the local network connection. The user is then no longer able to print to netwrok printers, browse the network, etc. As soon as you disconnect the DUN, the local network starts to work again. What could be causing this problem. By the way, the machine is running Win 95.

Thanks,

Slap

Could it be that there is no trust bewtween the local machine's Domain and the dial-in Server's Domain?

I don't think that is it. It is just like dialing up an ISP. I have now problem doing it on my PC. I can dial out and still have my network connection.

Maybe this microsoft article could help you:

BTW are you using HUB at work instead of switch ?

We ran into this problem about a year and a half ago. There is a Knowledgebase article somewhere (I'll try and find it), but basically you cannot bind TCPIP to both your NIC and Dialup Adapter at the same time. That is why you lose your LAN connection when you connect with your dialup adapter.

This isn't the exact article, but it will give you the general idea:
Article 150053

Really?? I never knew that... How come my network at home works then? Could it be using IPX on the network when I'm connected to the net? BTW, is there any way to see what protocal your using while your transfering data between computers in your network? hmmmm... but as I recall, my network still worked even when I only had TCP/IP installed and connected to the Internet using a modem at the same time.

I never got any problem when I bind TCP/Ip with my nic and dialup adapter. Infact my home network is running without any problems.
BTW Slap, have you install the latest service pack (6a) for your NT server yet ?

well, if you remove everything except TCP/IP, that would test it for good (do you even USE programs that need IPX? if not, take it off!).

yes there are ways to monitor traffic on a per protocol basis.. do a search on network inspector (or monitoring) programs.

I suspect that some devices want TCP/IP to itself, but not all (which is why this problem isn't that common, a fair amount of people do the same thing you are trying to do).

Does your LAN have more than one subnet? A DUN connection becomes the default gateway, and LAN connections are then limited to the local subnet. For LAN connections beyond the local subnet, while DUN is active, you'd edit the routing table and add static routes in order to access your LAN's other subnets.
