Web service call not supported in Web Player

hi all,
Its said in the documents of Unity 3D that importing plugin is disabled in the web player mode.

And my problem is very close to this.
I made 2 .Net Dll file that i am using in My game.
one that contains a webservice call with in one of the function of the Dll using a web reference and the second Dll with a simple function with out any webservice call or with out any Web reference.

And now the problem:
While i run this in the standalone mode in Windows i get the result from both the dll function. Ans as soon as i build and run this in Web player mode from unity, the game starts, but i dont get the result from the function called from the FIRST dll that which contains a web reference call. But On the other hand, i get the proper result from the other second DLL that which doesnt use any web reference.

why is this happening?? is there anything that i need to take care while i use a web reference DLL in my Game?? Or Do u think i had done anything wrong in this procedure. pls let me know your feedback. Bcos i need to solve this issue very urgently.
If possible provide me the procedure or precautions if i need to take care of.

Any suggestion would be most appreciated.

Thanking every one in Advance

from a recent thread it looks like the webservices rely on System.Environment.MachineName which is a no go as System.Environment is compeletely removed on the webplayer like any machine access

Okey so using a DLL or the classes from the .Net is the problem it seems. Bcos when i use web service call directly, thats is with out using a DLl and simply using WWW, and i get the response. But the problm is i am not getting a proper output when i try to call a custom web service that is created by me. A simple Number adding web service.

the details of the service created is follwed as a Image.:

right, WWW does use the browsers networking. But if you use assemblies from 3rd party its likely using the regular .NET System.Net.HTTPRequest or alike which seems to rely on System.Environment and thus does not work.

depending on what you want though its no problem.
for example json communication is very well possible with WWW and json libraries

for SOAP I don’t know if there are such libraries
