HI Vijay,
Are you sure the Archestra OPC Server is enabled? All OpcEnum does, when used by PCo, is enumerate the Registry to find the connection details for all installed OPC Servers.
1. What OS is running on the machine?
2. What is version of OpcEnum.exe?
2 What is the version of PCo 2.3 that is installed?
4. Is there an OPC client installed on the Archestra machine? if so, can this client see the Wonderware DA Servers in the OPC Servers list?
Regards, Steve
