I am new to OSI-PI and OPC. I was trying to run an OPC example that was used by http://vCampus.osisoft.com/media/p/1180.aspx. I have a PI Server install on a 2008 Server box. I was able to to access the snapshot and archive Values from that PI Server from my window 2007 box using PISDK. So PISDK works. Next I tried OPC example. In the original example:

 

1. Opc.Da.Server myOPCDAServer = new Opc.Da.Server(new OpcCom.Factory(), new Opc.URL("opcda://localhost/OSI.DA.1"));

 

2. myOPCDAServer.Connect();

 

Here I am trying to use the installed PIServer as OPC DA Server. Since it is installed on the remote box. So I modified the new OpcURL in line 1 into

 

new Opc.URL("opcda://ipaddressThatHasPIServerInstalled/PIServerName"). But after the modification line 2 still fail to connect. I did the debug. The exception message is " Invalid value for registry".  any idea ?
