The Web Service has been implemented using
WS-Security so it expects a Username/Password
token (with PasswordOption.SendHashed option).
I've built this using MS WSE 2.0 SP3 in VS.NET.

I've also created a Windows Form application
which acts as a client to the webservice.
The WS resides (network domain is, say, testinginternal.com)
on e.g. http://mytest.testinginternal.com/testservice/summary.asmx,
this is the URL used to create a web reference for the client.

Before deploying the webservice it resided on my
local machine (network domain for local machine
is different, say, developerinternal.com), I tested it
here using the local URL
(http://localhost/testservice/summary.asmx)
as the web reference. Everything works fine when using locally.

Now when I call one of the web service functions
(on the WS server), supplying my username
and password, from my client (on my machine), the
call fails with the error
"An error was discovered processing the <Security> header".
If I move my client, to the server holding the web service,
and call the WS function again supplying my username and password, it works.

Any suggestions/solutions would be helpful.

Thanks
