problem with webbrowser control/ webservice/ firewall client for isa server 2004

Hi,

I'm developing an application in C# with Windows Forms for my company
that is similar to the MSN Messenger. This application uses a
webservice for registering users, etc... and as 2 webbrowser controls
on it. Besides that i'm using the firewall client for isa server 2004
and it seems that the browsers aren't able to pass thru it... if i
disable the firewall the browsers work fine, if i don't, the 2
browsers just stay there processing something. It doesn´t return any
error...
But the rest of the application works fine it contacts the webservice
to register the user and all the other stuff works, only the browsers
don't work...

Now, this webservice is allocated on a server outside of our intranet,
before that it was located in our intranet and at this time the
browsers worked fine... Only when we started to reference the
webservice outside our intranet, that the browsers stop working and
have this strange behavior. I even tried to access some sites like
google or even pages located in my machine and it as the same
behavior...

I've developed an application with the webbrowser control and it
worked fine with the firewall client, also the webservice is working
well with the firewall (or else i wouldn't be able to login in the
application). So, i believe that the problem is related with all the 3
things working together (browser, webservice and the firewall client).

I've seached the internet for any similar situations but i haven't
found anything... i'm going crazy with this problem.

Does anyone as some asnwers for this??

Thanks in advance for any answer,

Miguel

Hi,

Is it a problem with proxy server settings?
We faced a similar problem.
We developed a webservice consumer client application.
It was working fine within our LAN, in our hosting setup.
When we tested our application from client's office, it didn't work.
We could access the webserver using the browser.
But we couldn't use our client application and consume the webservice.

After we found that it is the issue with the proxy server, we fixed it in
the webservice consumer client and it worked.

R.Balaji

Hi,

Yes, it's a problem with the proxy server settings, but not with the
ones of the webservice. It's with the proxy server settings of the
webbrowser control.

I've already come up with a solution to the problem, but I don't know
exactly what's causing it...

What I have done was to navigate to the web page before the
application calls the webservice. It seems that the proxy settings to
the webservice screwed up the proxy settings of the webbrowser
control, at least that's where i think the problem resides...

But the solution works perfectly for now =)

Regards,

Miguel
