HTTP Error 501/505

I created a web service on a SQL Server 2005 inside an office network (LAN A). Using the visual studio on my home computer, I was able to add the service as a web reference. The web application, running on VS internal web server, used the web service successfully. Also, I could retrieve the wsdl info using both IE and FF from the home computer.

However, on a PC in another office network (LAN B), I got the following error when trying to retrieve wsdl info using IE.
********************************
This error (HTTP 501 Not Implemented or HTTP 505 Version Not Supported) means that the website you are visiting doesn't currently have the ability to display the webpage, or support the HTTP version used to request the page.
********************************
On that PC, I was not able to add web reference (using VS) and got the same error because, VS uses IE to browse.

The .net framework and the IE on both my home PC and the PC in LAN B are the exact same version.

The possible reason for the error, as I can think, is that LAN B is behind an ISA server, while my home PC is behind a normal router firewall. Maybe some settings on the ISA server made difference?

Any feedback is appreciated. Thanks in advance.

By the way, I had a similar post at the "SQL Server Setup and Administration" forum and got no response. This issue is related to SQL Server, web server, and asp.net. I apologize if I still posted in the wrong forum.

actually it's just related to IIS and HTTP protocol. the fact that it's written using asp.net or that the web service talks to a database isn't the issue.

Either LAN B doesn't know about LAN A or there are security issues between the LANs. create a static html page and host it on LAN A's web server. The attempt to access the html page from LAN B.

the html can be as simple as
Code: 
<html>
<head><title>test page</title></head>
<body><p>hello world</p></body>
</html>
once this is working then get a simple web service (not db access) working. then wire up the database to the web service and test.

Jason,

There is no web server inside LAN A so I cannot make the test. LAN A only has a SQL Server 2005, which is able to set up a web service without using a web server.

I got my web application working in another web server, in LAN C. So it proves that something is not right in LAN B's Firewall. Is there any setting on the ISA server that may cause this problem?

you would need to talk to an ISA administrator. There is a forum on tek-tips for that forum802 . I would also check google groups and yahoo groups.
