TCP/IP Stack Woes

By pdminer ·
I am unable to use our office ISDN line across our network for mail or internet (IE5.5) I have a separate dialup modem and all works perfectly, albeit, slower. I deleted the TCP/IP stack and shut off networking, and then reinstalled - no change.

I can ping, telnet, and ftp separately, but as soon as I use IE or OE, no luck. Any Ideas?

That sounds like a subnet problem to me. I would like more information on what kind of network you have.Ex. Client server or peer-to-peer. How are you sharing the internet access?

In your PC's TCP/IP setup, the router's IP address must be listed as a Gateway. Also, your PC must know the address of one or more Domain Name Servers (DNS) in order to locate addresses on the Internet. Gateway and DNS addresses can be assigned by the router if you enable the router's DHCP function and reboot the connected PCs after the router is configured. You can check the PC's TCP/IP setup by running 'winipcfg' (or 'ipconfig' if you are running Windows NT). Click the Windows Start box, select Run, type winipcfg, and click OK. Verify that the Default Gateway is the router's IP address, and that one or more DNS addresses are present. Hope this helps.

Already checked that; ip's are as they should be. Is it possible that changes in the handling of TCP/IP by IE5.5 might be responsible?

I have seen a bug in windows where for some reason it tries to use the same DNS settings for both the Dial Up Adapter TCP/IP and the network card TCP/IP settings. Make sure the DNS setting is correct on the Network card TCP/IP (not the same as the dial up DNS!)
You could have a problem with the wacky "security / content advisor" portion of IE 5.5 ..

Does your company have a proxy? Is your IP in the range for the NAT table? Also, you might try the IP settings and login ID from a known good machine.

no proxy, and I have been at every machine in the system. It's a puzzle!

1. Telnet to your e-mail server Ip on port 25. You should get a response that says SMTP is available. Then do port 110. It should reference POP service. Then do port 80 on your web site and type HELO. You will get some message back (good or bad). If any or all of these time out instead of respond, you have IP problems.

2. If 25 and 110 work, your mail settings in OE are incorrect, your mail account has become corrupt or the gateway to the mail account is not letting you through.

25 and 110 worked just fine but webpage www.gettings.net neither responded or timed out, just connected and sat there. What does that mean?
