Infact when i try to Register a server as a local server,
By writing the entiries viz.. progID and CLSID ,they are registered perfectly, but when i try to retrieve the CLSID in a client to open the server using a function CLSIDfromProgID, it returns an error "The Resitered CLSID for the ProgID is invalid.
I think this info is sufficient

Maybe two things make it:
1:the function CoInitialize(NULL) is not called.
2:the ProgID is UNICODE, not ANSI
the following is some sample code,hope it help:

CLSID clsid;
CoInitialize(NULL);
WCHAR m_WCHAR[100];
MultiByteToWideChar(CP_ACP,0,"DAO.Relation.35",
 -1,m_WCHAR,100);
//here I get clsid of dao.relation
CLSIDFromProgID((const unsigned short*)m_WCHAR
          ,&clsid);
