Loosing TCP/IP on Workstations

I have an intermittent problem, which has occurred on 2 laptops and one desktop PC. It has happened under both 95/98. They all have a customised version of IE5.01.
The users log in and all seems fine. They get IP and they use the INET. When closing IE5 and going back in, they get the page can not be found error. While checking further, if I use winipcfg I’d get a fatal error: IP not found. When pinging the gateway, no response. The only recovery is to reboot, but it is happeningquite frequently. One of the guys is our web admin, so you can imagine the dilemma. For further info, we do have a proxy server, but I think this is irrelevant. I’ve tried searching the Microsoft site but found nothing. Anyone have any ideas?

You didn't say how they get to the Internet. Do you have a router?
Do you use real IPs in your network? If not, how do you do the name translation?
Do you use a firewall?
If you use real IPs, go to IE Tools, Internet Options, Lan Settings, and clear out everything. Also, in the advanced tab, check all HTTP options including the proxy one, and all java options, and bellow all the protocols available.
If you use some kind of name translation like a firewall, reset or reboot it.

Good lick!

We use real IPs, no DHCP. We have a firewall, but I don't think it is to do with it. It's now happened on 95/98/200pro, so I think it is to do with IE5, the nic, or the Novell Client, although it doesn't affect anyone else. I've changed the nic...don't know where to go next though.

I'd add an entry for the proxy server in the hosts file and also manually enter the IP or resource name manually instead of using the autodetect proxy (which is what I suspect is set).

At that point, I'd be looking to see what's going wrong in my stack, such as a imsmatched file (usually reinstalling takes care of this and overwriting new files takes care of this)

Hope this helps you

we manually set up the proxy, that is all the customised setup for IE5 does, plus adds some links and favorites. I've reinstalled several times, and it has now happened with 3 operating systems.

you can try going into control panel and go to add remove programs, select ie5 and click remove select the option repair or go to a earlier version. You might also have to extract your winsock and wsock32.

tried this, going to another version isn't an option. I've compared winsocks to other PCs that have no problems, and they match.

From your statements, it sounds like you are running a DHCP server. As a way to test if it's the DHCP causing the problem. manually assign an IP to these 3 devices within your IP scheme. then see if the errors keep happening. If the problem goesaway, then your problem deals with your DHCP server and the clients setup to reach them. It's possible that the arp tables on these machines are also messed up. Check the arp tables, assign an IP manually, and see if it works. Hope this helps.

Under Windows 95 I use a batch fix that MS installs on the hard drive whenever I run into TCP/IP problems ...
restart in MSDOS mode

It will take you to c:\windows prompt

cd ws2bakup

ws2bakup.bat

It will run the backup file for Winsock 2install and restore the IP address function.

It sounds like IE is hosing your TCP/IP stack as it is closing down. I've had some bad experiences with customized browsers and I think the first thing I would try is to install a standard browser and see if you still have the problem.

There is a lot of excellent thought behind some of the other answers, but the key piece of information in my mind is that everything works fine until they close IE5 on these particular workstations. In my mind, that would rule out the DHCP, routing or proxy issues that have been suggested.

However, I have been wrong before...

I agree that I think it is IE5 related, but we have no other options, the customization only does a full install and sets up the proxy with some links and favorites and resets the home page. Nothing to fancy that could screw anything.

If you are running NOTES, it can disable the proxy settings giving errors also.
