Thanks anyway Andrew. I tried it with a few machines but it doesn't
seem to help. I had thought of the IPv6 thing as well, but from the
posts I had seen on the Apple support discussion board for ARD I think
this is an ARD issue.

Oops. Sorry, Dan. I meant to say "I haven't seen this exact
problem..." What's a couple letters here and there?

Dan,
I have seen this exact problem, but I would try disabling IPv6 on
your machines, and disabling ARD's reverse DNS lookup on your ARD
admin machine. Here's the gist of it:
# On _all_ your affected Macs, turn off IPv6:
networksetup -setv6off Ethernet
networksetup -setv6off AirPort
# And on your ARD Admin machine, add turning off ARD reverse IP
lookup:
defaults write com.apple.RemoteDesktop DisableReverseIPLookup -bool
yes
networksetup -setv6off Ethernet
networksetup -setv6off AirPort
Hope this helps.

Hi All,
Over the past six months or so we've had problems with the status
of our machines not refreshing in Remote Desktop, which makes it
difficult if not impossible to send unix commands or perform other
automated tasks on one or more client machines. Using the scanner
set to either Bonjour or Local Network will refresh some, but not
all of the clients (most remain greyed out).
There are two recent changes in our LAN setup which I believe
relate to this issue. First was upgrading from our old Linksys
firewall to a SonicWall NSA 240. Second, and I believe this may be
the key, was re-numbering our network from a traditional
192.168.x.x (class-c) address space to a 172.19.x.x (class b).
Everything on the LAN is on a single subnet with an identical
255.255.0.0 mask, though machines are grouped according to type as
if they were class C subnets (i.e. .10 for workstations, .20 for
render machines, etc).
Could my problems be the result of a bug in ARD, or is there a
known limitation as to what addressing schemes will work with it?
Reinstallation of course has not resolved the problem. I am
currently running ARD 3.2.2, both admin and client, and a mixture
of MacOS X 10.5.5 and 10.5.7 on my machines. I have heard of other
people having similar issues since upgrading to MacOS versions
after 10.5.5, but Apple of course has not addressed or acknowledged
any such issues.
