Hi,

I have a small app that uses a web service to retrieve a dataset. Last
night everything was working fine, however I tried it again this morning and
I am getting an error:

A Managed SoapException occurred

Unable to handle request without a valid action parameter. Please supply a
valid Soap action.

I am really puzzled because no code was modified and the exception is thrown
by code auto generated by visual studio. I have restarted the web server
running the service (W2K SP4 IIS5 .net 1.1) and they work fine when tested
via IE. I have also created a new project and added the web reference, and
I still recieve the error.

I have tried searching for info on this type of error, but there is very
little to find.

Any help would be greatly appreciated,

Hi,

Starting to see some light at the end of the tunnel. From what I can tell
our firewall/NAT is causing a problem. When connected directly to the net
via a dialup connection everything is fine. However when connected to a
2003 Small Business network via a watchguard firebox, I have a problem. The
firebox is configured to allow Internet access (port 80), I thought that the
SOAP requests used HTTP and would therefore pass through?

Hi,

The problem is now resolved. Turned out that the firebox was removing the
SOAPAction header.
