Experimental Physics and
Industrial Control System

i can reproduce your error message on my win2k system with a "caget"
command at the command prompt whenever "caRepeater" is not running.
(check it by launching and stopping it manually.)

caRepeater.exe is started automatically by the ca.dll - probably with
ca_task_initialize. in order to suppress the message in your code,
waiting until caRepeater is running may help. i've never got the error
with my own code which uses direct ca.dll calls - for what reason ever.

besides, i'd like to emphasize that channel access runs very well on my
win2k system. i write a client application for a photoemission
spectroscopy experiment that runs under EPICS. the code is written in
borland delphi (object pascal), and it wasn't a big deal to access
ca.dll functions directly.
