NT4 and Dial-Up Connections 18

Posted by Cliff from the getting-it-to-work dept.
John_D asks: "Hopefully, someone out there can help me with this one as it has been a nightmare. I work as a tech for a small company and we are trying to set up individual NT 4 Workstations that are on an existing LAN, to connect to a local ISP. Each system is using a local modem, but when it calls up and connects it cannot resolve the DNS. It can however resolve the ip address (ie www.microdorks.com doesn't work but 204.127.189.1 does). Is this something that cannot be done without a seperate profile for the modem off the network??? Do I have to make adjustments to the server? As this is happening with a number of configurations (different proxy's, system designs etc), I was wondering if there is a quick and dirty solution. Any help would be appricated."

    I've had a similar problem. I origninally had the "domain" setting filled in on one of the relevant dial-up properties sheets (i forget which), and when I blanked out the field, the problem disappeared. That was a simple network that only used netbeui on the lan.
  • Wait a minute.. You're the one who has no clue what you're doing, and the people pointing this out are the bad sysadmins? Am I the only one who sees the flaw in this logic?

    Odds are, you filled in one of the text boxes incorrectly. I'm suprised Cliff even bothered to post this one.
  • I agree with the AC here.
    I am an IT contractor working in the UK and never a day goes by without me being asked whether or not I'm certified.
    I have over 5 years experiance of sys admin on various platforms but I have spent the past few years as an NT sys admin. I have been responsible for small 20 users lans up to global, multi-master, 12,000 users installations. But I do not have the MS certification so I get passed over for contract possitions for people with 3 weeks in a bootcamp as their experiance.
    In fairness it's 50/50. Guys without any knowledge go out and fuck things up for the rest of us and companies put to much faith into resumes and certifications.
    In an ideal world this would be eliminated by simply giving people through technical tests prior to offering them a job and by asking for references and copies of certificates.
    Still, until then, STOP WHAT YOU ARE DOING AND COME CLEAN IF YOU ARE A FAKE SYS ADMIN. You are not doing anyone any good by fucking things up and putting in "quick n' dirty" fixes. I would much rather turn down a job than be found out as a fraud.
    Just my £0.02 worth any way.
  • Add the DNS servers in the ***Properties*** dialog in Dial-Up Networking, NOT in Control Panel-Network-TCP/IP.
    The way we do it, the DNS servers for the LAN go in the Control Panel, while the DNS for the dial-up connections go in Dial-Up Networking (duh).
  • I'm assuming you are letting the station ask for it's servers. Dont rely on the remote PPP server to dictate the DNS servers. Specify them by hand in the dialup properties. It's been over a year since I've used NT to dial anything, but it should work.

    As far as profiles for modem or no modem, network or no network, dont worry about that. NT can actually handle being multi-homed but 9x has some odd problems and requires some coaxing.

    I hope this helped! You can email me at the above address if you would like. Take care.
  • Hi.. I have some NT experience- i'm a student employee for the dept that keeps the labs running at my university.. but i'm not sure if this'll work, because i can't test it now. (disclaimer here!) anyway..

    Could you stick the ISP's dns server into the tcp/ip properties control panel as the 2nd or 3rd entry in the list (assuming you've got one dns server listed for your lan already)?

  • yup, you got it.

    BUT this will only allow internet access for that particular machine. (as far as i and my supervisor know)

    i work for a tech support company (we do tech support for isps all over the country) so i have run into this before. Ross got it right on how to set it up, but something else you may want to consider is setting up a firewall (annoying, i know, but it helps) or doing ip mascarading (can't spell that). either one will work. this must be done if you want the entire network to be able to access the internet through that dial up connection. there is also a program called WinRoute (so i understand, i havn't seen the prog myself) that will do pretty much the same thing, and allow that NT machine to act as a router.

    the other solution is not to use NT, but instead 98. the upgrade for that OS includes a setup where multiple computers can share the same dial out. i havn't tried it, but i understand it's there and that it works.

  • To set this up you need to set up the DNS in two different places, as you have two differnt DNS's.
    The first place is in the network settings:
    Start -> Settings -> Control Panel -> Network. Under the protocals tab, tcp/ip settings-> propreties. DNS Tab. Here you want to enter you LANS DNS numbers.

    The second place is:
    My Computer -> Dial-Up networking, select the place you're calling, then click "more V" and select the first option (Edit Entry and modem propreties), click the server tab, TCP/IP settings and then you can enter the DNS for the dial up networking.

    This should use the DNS for the LAN first, then the DNS for the dial up when connected to the ISP.

  • Try *gasp* calling up your ISP and asking for help on how to setup a NT4 machine.

  • #1 I agree with the technical correctness of most of the answers given to this response. #2 I am suprised the 'use a router' answer didn't come sooner ;) #3 I don't think that anyone should be responded to in a negative fashion for asking a question (yep, even the silly ones) 'cause there is no real value to knowledge if it is not shared. All IMHO of course ;)
