My suggestion on your post: http://kixtart.org/board/Forum1/HTML/002522.html

was meant to be used locally during login.
i.e. As part of the normal login process
each user would locally process this read and then your code would take action
based upon what it finds. You might want to periodically check how often the
user gets the GRC.DAT file, or if you only have one Parent server I guess it
is not that bad. We copy from about 20 different servers based upon their
IP address. However, dialups and other multiple nic cards do cause problems
with trying to update the GRC.DAT file. You may need to be a little more creative
with the code depending upon how you want the Parent Severs set and clients
controlled.

Remote Registry reads are prone to various problems. Unless there is some other reason not to
have your users run the login script each time and do this read,
I would recommend doing something locally and not doing it remotely.
