Several months ago, when I updated my SLS server from 10.6.1 to 10.6.4,
screen sharing suddenly stopped working on the box. Trying to connect to my
server’s screen via either ARD or “Share Server’s Screen…” in Server Admin
would yield a connection failed message.

Telnetting to ports 5900 and 3283 would yield a connection refused message.

Neither ARDAgent or AppleVNCServer were listed as running processes.

Trying to enable ARD using kickstart would return a “Activated Remote
Management” message, but did not solve the problem.

I held out, thinking that this might be a bug with the 10.6.4 update that might
be fixed with 10.6.5.

However, after having updated to 10.6.5 (first 10H574 and now 10H575), I still
cannot remotely manage the screen of my server.

This is becoming extremely frustrating, and I’m hoping someone out there
might have some tips as to how to get to the bottom of what’s going on, and
solve it.
