Hi.

I just run into a misfeature again that I already stumbled over a year
ago: host names for CA and AS are host sensitive, whereas in all other
places the case of host names is ignored.

(See: http://www.aps.anl.gov/epics/tech-talk/2002/msg00121.php)

This time the problem occurred when a windows client machine was updated
from NT4.0 (where CA transmits the host name as lower case) to
Windows2000 (where the same name gets transmitted as upper case). As
this machine is a double boot thing that is supposed to run both
platforms depending on its use, I had to add two hostnames to the AS
definition file, one in lower and one in upper case. This just doesn't
look like the best way to handle the issue.

What if both the CA client lib on startup and the AS lib when reading
the definition file convert host names to lower case?

Does 3.14 handle this already in a better way? (I don't have 3.14 on a
WIN system to test.)

What do you think?!
Ralph
