IE connection settings not sticking on LAN ...

[YeOldeStonecat]

Here's an odd one. Yesterday, changed over a network that ran on a frac-T, to a large global VPN WAN on another fatter frac-T.

Before, I had several NT servers, but an NT 4 PDC that ran DHCP...handing out the local IP address, the gateway, WINS, and DNS servers. DNS from the ISP. Never had a problem.

Change over to the new scheme, a WAN tied to the U.K., following their IP scheme. It's a global VPN network, using a proxy server that they specified. I reconfigured DHCP to hand out the new IP scheme, the new gateway, the new ISP's DNS servers, and WINS. We reconfigured IE settings to use the proxy server's IP address, and port. Seemed to work fine. But hours later, many computers seem to "lose" these settings, auto configure becomes checked again, and the manually configured proxy settings are grayed out. Reset them....works immediately, yet gets lost again.

Leaving on auto-configure does not work.

Ideas anyone? Is there a way to hand out proxy info using DHCP or something in the login script? I guess I don't need to hand out DNS or the gateway if using proxy.....just used to doing that. I really don't have much experience with proxy.

YeOldeStonecat :many computers seem to "lose" these settings.
You know 100 x more then me on VPN !! But from reading your post one thing jump out , ( not all are lose setting )I find it very odd.I would look very close at the set up on the one that hold there setting .Then look at any switch that may be between the one that are loseing setting.and the route the line may run ..Just a guess but ( old nic card or an old Switch.

Symptoms
The version of Internet Explorer included with Microsoft Office 2000 does not retain the automatic configuration script address when you click to clear the Use automatic configuration script check box. Instead, the address is deleted and you must enter the address again to be able to use this feature.

Has resolution and links to download a patch that has only had minimal QA....yikes.

What is the OS and IE versions?

Hmmm....will give that a shot Skye....it mentions IE 5....the first thing I did yesterday was go to 5.5sr2 on a couple of machines...and it didn't do the trick. But from this article, I'll go and compare that wininet.dll file...perhaps IE upgrades didn't overwrite that.

I did not read any mention of a 2000 DC on the network, working as a field technician for AT&T, when we were @Home a manual proxy was specified in the registry, when @Home went under I had to manually go into the registry for my customers and remove the proxy setting. You might try checking the reg for such manual entries. The one thing I was not clear on was do the browsers in question loose setting when the browser is closed or while active? Are there any Group Policy settings for a certain group of users that would specify a proxy setting? (again I don't know is 2000 exists on network)

Tis just an NT 4.0 domain as stated above....all servers are NT 4.0, including the PDC.

Clients are all a mixmatch, couple of old 95 machines running data collection in the plant, most offices have 98se, or 2KPro.

All IE versions are at least 5.5.

Curious where that registry entry is......
