Web proxy and Firewall client - 8.Aug.2005 9:17:00 AM

Strange problem just started happening within the last 2 weeks when using webproxy or FW client.

When opening IE it sits at Detecting Proxy Settings for approximately 30-45 seconds. This happens when the Automically Detect Settings is checked and also happense with the FW client installed. If I uncheck all settings in Tools, Internet Options, Connections, Lan settings my home page pop ups in seconds. I know this wasn't happening before becuase my EU's would have been complaining about it.

I've not changed anything that I am aware of.

Any thoughts would be most welcome.

Thanks.
Jim

Hi Jim,

Where do you see the delays in the packet traces?

Thanks!
Tom

Hi Jim,

can you provide us with an URL where we can download the trace file?

Also, you should check out http://www.isaserver.org/articles/ISA2004_ClientAutoConfig.html .

HTH,
Stefaan
