I have configured DX in bothdirections with a 3rd party OPC DX Server (running on the same PC)and it's working fine even when I shutdown &restart the PC (gracefully). But if I lose the power and the PCreboots (have auto logon) I see no connection under DX\Source Servers\<3rd party OPC>\Status\ConnectionStatus="disconnected" and SourceServerConnected=True [:mad:] 3rd party OPC Server DX is configured to start as a service and is up and running by the time popup PCStation/SimaticNET is starting up. In the oposite direction 3rd party OPC DX is connected toSource Server (SimaticNET OPC). If I cycle False - True the SourceServerConnected tag then I can communicate again with 3rd party OPC DX (ConnectionStatus="connected") See bellow the log from OPC_DX.err file: * SIMATIC NET OPC-Server DataAccess-V1.0A/2.05 DataExchange-V1.0 (C) SIEMENS AG 2004: Start [V01.03.00.6 release] * Instance:C:\Program Files\SIEMENS\SIMATIC.NET\opc2\bin\opcdxserver.dll * Date:15. 8.2006 * 6:27:36,991\|009C* >DllMain DLL_PROCESS_ATTACH 6:27:36,991\|009C* <DllMain DLL_PROCESS_ATTACH 6:27:37,862\|009C* -> DXInit 6:27:37,862\|009C* > GlobalInitialize 6:27:37,862\|009C* < GlobalInitialize 6:27:38,142\|009C* <- DXInit [hr=0] 6:28:22,259\|009C* -> DXStart 6:28:22,259\|009C* <- DXStart [hr=0] 6:28:22,259\|0120* FAILED ConnectIVar2: no connect since the RT Status is DOWN Thanx Dec

What I discovered when browsing the Computer services was that the status of all my SimaticNet OPC connections were reporting "Starting" rather than "Started". No matter what we did we could not resolve this and therefore reverted to a re-installation of the SimaticNet software. After the re-installation we were back up and running.
