ISA Server error
Struggled with following error yesterday:
Error
The request failed with HTTP status 407: Proxy Authentication Required (The ISA Server requires authorization to fulfill the request. Access to th Web Proxy filter is denied)
This turned out to be due to the fact that I use a central proxy server. The error comed up each time I try to open a Visual Studio solution which uses web-services. Since the web-service is running on my local computer I really don't need the central proxy server, and it should not have been contacted at all. To turn of the feature and thereby solving the Visual Studio error, do the following:
- Start Internet Explorer
- Go to Tools->Internet Options
- Choose Connections
- Choose Lan Settings
- Remove the check box checked for "Bypass proxy server for local addresses"
- Restart Visual Studio

Hi! I know this is kinda off topic but I\’d figured I\’d ask. Would you be interested in trading links or maybe guest writing a blog article or vice-versa? My site addresses a lot of the same topics as yours and I believe we could greatly benefit from each other. If you might be interested feel free to send me an e-mail. I look forward to hearing from you! Excellent blog by the way!

Hi,
My problem with that solution is that we are using an automatic configuration script with our ISA server and I can’t change this option, so is their any ways to tweak visual studio to use the local help files without passing by the isa server… if in the adress bar, I change 127.0.0.1 by localhost, it works, but I can’t ask my user to do that all the time.
Thank you
