Proxy Server keeps redirecting internal URL externally

[Gunnerwinthelot]

Hi all,

We are runing a Win 2K proxy server and are having a strange error. We have an internal server on the same subnet running W2003 server and IIS. It is running an internal web-site that only seems to work if you bypass the proxy, therefore disabling your ability to browse the web.

The error we get is:

The requested URL could not be retrieved

--------------------------------------------------------------------------------

While trying to retrieve the URL:

http://bpgs03/insynergy

The following error was encountered:

Unable to determine IP address from host name for bpgs03
The dnsserver returned:

Server Failure: The name server was unable to process this query.
This means that:

The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.
Your cache administrator is root.



Can anyone please point me in the right direction to resolve this? Putting the IP address in the URL instead of the server name doesn't help, nor does adding that URL in the list to bypass on your web-browser.

Thanks very much!

David.

Hi, is the subnet defined in your LAT?

** Try to configure the "bypass proxy fol local addresses" in IE to match your internal domain. (tools, options, connexions, lan settings).

Try to define a wins server (if you have one) in the TCP/IP configuration of your internal NIC.

Hope this helps. Please let know if this resolve your issue

The proxy is unable to resolve the name bpgs03/insynergy, so it attempts to resolve using DNS.

In internet explorer, you can define which addresses should be exluded from using the proxy.
Tools, Internet Options, Connections, Lan Settings, Advanced, Do not use proxy server for addresses beginning with
In here put the machine name bpgs03.
Restart IE and all should be better.

Tried that before, didn't work! We've resolved it temporarily. We had effectively two proxies, one WebMarsal server inside the firewall, then one MS Proxy Server in the DMZ. The WebMarshal server points to the MS Proxy and the MS Proxy then points to the internet.

Pointing the internal Proxy (WebMarshal) server directly to the internet seems to have resolved it. No idea why....any thoughts?

Thanks!
