Exception from HRESULT: 0x80040154

Hi,
I'm deploying a silverlight project in a Windows xp machine. This project is calling a WCF Web Service to get data from a GeoDatabase and it is using arcobjects.
When it is going through the web service, I'm getting an error after excecute this line:

serverconn = new ESRI.ArcGIS.Server.GISServerConnection();

Retrieving the COM class factory for component with CLSID {CD57B642-1B4A-4E02-A1D0-FFDBCF0E5A41} failed due to the following error:
80040154 Clase no registrada (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).


I have installed ADF for .Net in the server.

What could be happening?

Thank you!
ED

Try using ESRI.ArcGIS.ADF.Connection.AGSServerConnection

Look at this thread:

Still a problem.
In my laptop it works fine, but when I'm implementing the web service in the clean server it doesn't work. Actually is not a server, it is an other XP machine.
I think that I have to register something or install something to make the arcobjects of the web service works , but I couldn't figure out what. I've intalled ADF .Net, tried regasm of the esri dlls in the server but it didn't help.
Some idea?

Thank you in advance.
ED.

Installing the Server Object Container solved this issue for me.
