I have a small network of WinXP, Solaris 10, and Linux machines.  The
WinXP machines run Hummingbird Exceed and we expect that the Solaris
and Linux boxes appear in the Display Chooser window when running
XDMCP broadcast.

The Linux boxes appear in the list.  The Suns will disappear from the
list.  They tend to reappear when we restart dtlogin on them, after
which they'll appear for a period of time and then disappear again.
The Suns all have the rest of the network defined in their Xaccess
files.  I don't see any tell-tale errors in any of their logs.

I've been told that this "used to work" - how can I get these Suns to
consistently show up?

Thanks!
