Is there a stupid mistake maken here? I also have a server class but I think the problem lies here...
    // Constructor

CDPlayClient::CDPlayClient()
{
	this->mDPClient = NULL;
	this->mDPAddress = NULL;
	this->mDPDevice = NULL;

	CoInitialize(0);					// Init COM

}
// Destructor

CDPlayClient::~CDPlayClient()
{
	mDPClient->Close(0);
	ReleaseCOM( this->mDPDevice );
	ReleaseCOM( this->mDPAddress );
	ReleaseCOM( this->mDPClient );

	CoUninitialize();					// Uninit COM

}
// Enumerate TCPIP network devices

GUID CDPlayClient::EnumDevices( IDirectPlay8Client* pDPClient )
{
	IDirectPlay8Address* pDPDevice = NULL;
	DPN_SERVICE_PROVIDER_INFO* pSP = NULL;
	DPN_SERVICE_PROVIDER_INFO* pSPPtr;
	GUID guiddev;
	DWORD Size = 0;
	DWORD dwNumSP = 0;

	if( pDPClient == NULL )
		MessageBox( NULL,"PDPCLIENT == NULL","ERROR",MB_OK);

	if( SUCCEEDED( pDPClient->EnumServiceProviders( &CLSID_DP8SP_TCPIP, NULL, pSP,
													&Size, &dwNumSP, 0 )))
	{
		pSP = (DPN_SERVICE_PROVIDER_INFO*)new BYTE[Size];

		if( SUCCEEDED( pDPClient->EnumServiceProviders( &CLSID_DP8SP_TCPIP, NULL, pSP,
														&Size, &dwNumSP, 0)))
		{
			pSPPtr = pSP;
			guiddev=pSPPtr->guid;
		}
		delete[] pSP;
	}
	
	return guiddev;
}
// Initializes the client

}

int CDPlayClient::ConnectTo()

	// Connect To

									NULL, NULL, 0, NULL, NULL, DPNCONNECT_SYNC )))
		{
			return 0;
		}
		
	return 1;

}    
The way I call it: myClient.mDPClient = myClient.StartClient( "ClientPlayer", "q", NULL, "192.168.1.2", 12344 ); assert( myClient.mDPClient!= NULL ); assert( myClient.mDPAddress != NULL ); assert( myClient.mDPDevice != NULL ); if(!myClient.ConnectTo()) MessageBox( 0,"Can't ConnectTo()","FAILED",MB_OK); Help???
