Hi Mark,

So the problem is only that local Windows clients can not see the PVs
from a soft IOC running on the same computer. This is only happening
on this computer, not other Windows computers running the same IOC
binary. (They are not running at the same time, so it is not a
duplicate PV name problem).
None of the EPICS environment variables are set except:
EPICS_CA_MAX_ARRAY_BYTES=10000000
EPICS_DISPLAY_PATH=P:/epics/adl
The Windows Firewall is not running, nor is any other firewall that I
am aware of.

Very strange. Have you tried setting EPICS_CA_ADDR_LIST to localhost (127.0.0.1) or even the PC's own IP address (which of course may change for your demo) to force it to search itself?

My guess is it's probably something to do with DLL versions somewhere since the problem is only on this machine — do you have two versions of ca.dll installed, maybe one from Win32 extensions and another that came with the IOC code?
