Is Configuration Server version 6.5 not supported by Platform SDK 7.2?

Hi All

I am receiving error 2 while connecting to a Configuration Server version 6.5 and I found out from the confserver log the following:

04/23/09 14:07:01.445 Trace kopgen01 Configuration Server GCTI-00-04541 Message MSGCFG_CLIENTREGISTER received from 292 ( Unknown NULL )

MSGCFG_CLIENTREGISTER

ERROR: Wrong attribute (41)…

The code I use had work succesfully with configservers versions 7.0 and 7.2:

        _ConfigServerProtocol = new ConfServerProtocol(new Endpoint(_ServerName,_ConfigServerUri));
        _ConfigServerProtocol.ClientType = ConfServerClientType.ThirdPartyApp;
        _ConfigServerProtocol.ClientName = "CustomApp";
        _ConfigServerProtocol.UserName = _UserName; // "default";
        _ConfigServerProtocol.UserPassword = _UserPassword; //"password"; 

        _ConfigServerProtocol.Open();

I suspect Configuration Server version 6.5 is not supported by Platform SDK 7.2 but I need your expert opinion.

Thanks in advance

Mark
