Re: NetDDE problem

Tom,
>From the link I posted above, it says:
"If IndustrialSQL Server must be run on Windows XP SP2, the patch installation will run an OS Configuration Utility. This utility opens specific ports that enable NetDDE and adds
Wonderware SuiteLink and Wonderware LogViewer to the firewall exception list."

May be see which ports are used on the non-SP2 machine and ensure thet are open on the SP2 machine.
