I am getting the above error while trying to consume a webservice from an
ASP.Net site. I have tested the webservice from the server hosting the
ASP.Net site via a web browser and the service responds with the correct
data. When I access the website that consumes the webservice, however, I
get "Unable to handle request without a valid action parameter. Please
supply a valid soap action". This also occurs when i build a WinForms
application to consume the same service.

This must be a server config issue as the same site and application
connecting to the same service works on another machine. Any ideas or
pointers would be greatly appreciated.

Thanks in advance,
Charles

Charles,
I'm getting the same message when referencing a webservice I've created.
The service is being reference through a firewall, and I've got the
proxy enabled in the application.

Have you had any luck in resolving this?

Yip. Thanks to Theresa Smallwood for pointing me in the right direction.
The problem related to our firewall blocking unknown headers. Soap headers
obviously classified as unknown to our firewall so as soon as i disabled
that, everything started working.

Excellent - I suspect that we're in the same boat. I've passed this on
to my system guy. Reckon I'll see if that gets it resolved.

Thanks for the reply!

Unfortunally firewall settings do not can help me... I think in my way
the problem is not related to firewall. I can connet another web
services through my firewall and can operate web service from Internet
Explorer but not from client app.
