Online Help Center / Data loggers and plug-ins / Re: OPC Server Connection Issue

I'm now able to connect up to the OPC Server using the MatrikonOPC Explorer.
However when I try to add a tag to view it, I get the following error:
asdlog.Instance.1 caused COM/OPC error 0x800706BA on IConnectionPoint.Advise()
Error string: The RPC server is unavailable.
Additional: Could not establish data callback connection on group ''
Interface address is 0x00B2033C
Vendor detail: AGG Software [http://www.aggsoft.com] Advanced Serial Data Logger OPC server
The firewall has been completely disabled.
Also for some reason on the OPC server 3.9.7.713 tab, there are no Active clients listed.
Shouldn't I see my laptop there?
Any ideas?
Thanks again.

Thanks for pointing me in the right direction.
I'm having a problem in section 4.2 Specifying OPC server properties.
When I click on the DCOM Config folder I am getting some DCOM Configuration Warnings.
And once I resolve them by recording several AppIds, the Test OPC Server object is not there to configure.
The computer is running Windows Embedded Standard Service Pack 3.
Is there something else I need to install beyond the OPC Core Components?
Thanks.

I am using the Advanced Serial Data Logger and have it commuicating with our serial device on a desktop PC.
I have enabled the OPC Server and am seeing my data in the tags.
Per the instructions I have also downloaded and installed the OPC Core Components Redistributable.
The computer is on the network and pingable from my laptop.
I installed the OPC Scada Viewer on my laptop and I'm trying to connect to the OPC Server but I'm getting the following error message:
Unable to retrieve OPC servers list from the specified host [The RPC server is unavailable].
The client can't establish a connection with the remote server.
Please check your firewall and security settings on the client and server.
Everything with the firewall appears okay on both machines.
I went as far as turning off the firewall on the desktop with the OPC Server running.
I also tried connecting with the MatrikonOPCExplorer with no success either.
Any help would be greatly appreciated.
