Hello, I new to this stuff so please forgive me if I do something out of place.

Summary of problem
==================
Following an Group Policy Change to enforce LAN proxy service settings in Internet Explorer, any client pc that uses dial up network (i.e. non proxy based settings) cannot browse using Internet Explorer 6 sp1.

Environment
===========
Server: Active Directory ? Windows 2000 SP4 ? all patches applied.
Client: Windows XP SP1a ? all Windows patches applied (except SP2).

Client Virus Checker Program: Symantec AV Corp v8.1.0.825
Firewall: Sonicwall Pro 200 (attached to the ASDL router)

More Information
================
The Internet Browser works perfectly on the LAN when using proxy setting, but when dial up using any other provider (ie. Freeserve) which is not proxy based and not on the Lan the message is ?Page Cannot be displayed?.

We are desperately trying to avoid a Win XP re-installation if possible !!!!

It is possible to ping a remote address (ie yahoo. 66.218.71.33) but not the Fully Qualifed Domain Name (FQDN) www.yahoo.com

This is what I have tried so far with no joy:-

1. Removed the Check from ?Auto Detect Settings?, & ?Use Proxy a Proxy Server? in LAN Proxy Settings of IE6
2. Undoing the Group policy change
3. Re-installing IE6
4. Winsockfix
http://indorgs.virginia.edu/centralalt/pc/win32/WinsockFix.exe
5. Checked for Spyware/adware ? using

6. Reset to the TCP IP Stack - http://support.microsoft.com/default.aspx?kbid=299357
7. Qhost fix http://securityresponse.symantec.com/avcenter/venc/data/trojan.qhosts.removal.tool.html
8. Independent Browser (i.e. Firefox) - http://texturizer.net/firefox/download.html

Any help is appreciated. Thanks.

What you need to do is create a new OU for Dial Up PCs and use a different GPO to apply to them to avoid the Proxy settings for other computers.
