0x80040154 – class not registered when tried to connect to 800xA OPC DA Surrogate from 3rd Party OPC Client
800Xa Version: 3.1
OPC Client is running on separate machine.
We able to successfully connect to AC800 OPC DA Server 3 successfully without any error.
But when tried to connect OPC DA Surrogate server from AS as well as CS, we are getting error as "0x80040154 – class not registered"
We are using same login and password in both OPC server machine and OPC client machine.
OPC Client Service is also running with same login and paswword as above.
This error code only seems to occur when the client application attempting the server connection is outside the domain that the server exists in. This particular error does not occur when connecting from a client application inside the domain to a server that is outside the domain on a workgroup.
Check DCOM Settings on both End.
This may help...
same problem but I'm trying to connect (directly using localhost) to a server that is joined to a domain.
I even tryed to connect a local user outside the domain but in that case it doesn't work at all freezing the AdvDSOPCClient.exe app. DCOM permission given as required.
I hate OPC connections :-(
