I'm writing an OS/2 2.0 application which makes use of the IBM LAN
Dynamic Link Routine (CCB2) Interface to the IBM Token Ring. I'm
having a trouble with the DIR.SET.GROUP.ADDRESS (hex 06) command
(all other CCB commands seem to be executing OK). The 06 command
is always returning me an error code of hex 54 (Invalid System Key
code). I'm not setting the PROTOCOL.INI System Key, so I thought
(according to the IBM documentation) it should default to X'0'.
However, it does not seem to be the case. I've tried ALL possible
system key values (0 to X'FFFF', it's just a 'short' value), but to
no avail. I've tried to setup various 'system_key' values in the 
LANDD_NIF section of the PROTOCOL.INI file, and specify the matching
value in my program, but again, no luck...

The IBM LAN Reference Manual claims that "this command can only be
issued by a system administrator using the System Key as defined by
the configuration parameters". OK, I know the System Key, but it
does not seem to have any effect. Should my application obtain some
kind of privilege to become a "system administrator"? Any other
ideas what might be wrong? I'd appreciate any kind of input since it's
a very urgent and important problem for me indeed.

Thank you in advance,
