ISA Web Proxy problems - 16.Jul.2003 2:52:00 PM

Guest

Hello all. I have recently noticed that we are getting alot of page can not be displayed messages while browsing certain websites, or when clicking on certain links within websites. This has just recently become a problem. Our ISA server is running on Win2k SP3. Our ISA server is also integrated with websense. Nothing has changed in our environment... Anyone have any suggestions why this is happening? Here is the error:

The page cannot be displayed
There is a problem with the page you are trying to reach and it cannot be displayed.

Hi Davida,

Are the clients using the autoconfiguration script?

Thanks!

this looks similar to my problem and i am using the auto config script. But it is coming back with a host not avalible. when I turn the script off and setup the proxy server with a basic proxy setup it works fine.

You may be experiencing problems with your DNS service, have you changed anything on your DNS servers recently which might affect performance? I had a similar problem, restarting the two servers solved the problem, hope this helps.

I'm having this problem too. Using autoconfig I sometimes loose the connection when the web server gets re-directed to a non-standard port. If I manually config the proxy, it ALWAYS works. When I use the config script (wpad.dat)it always fails when a site I've been accessing with port 80 gets redirected to the same site and its NOT port 80. any ideas?
