I'll just add that trying to integrate Tiger into a domain is a real PITA as well.
You have to turn off digital signing because Tiger doesn't support that. Passwords have to be in clear text and there are some arcane SMB commands I ultimately ended up running at system startup just to make copy operations as quick as I could. Ultimately, this forced an install of DAVE to our Macs just to integrate with the server.
Mail in Tiger does not support Exchange either. Luckily for us, at the time we had Office 2004, but if I had had to use Mail we'd have been screwed because we had an Exchange server at the time.
Thankfully, I didn't have to mess with settings really when it came to Leopard. Apple has made strides in the past few operating systems in regard to networking, but I still much prefer Leopard and even Panther.
Panther was the absolute most stable version of OS X I've worked with yet. Boring as hell, but totally stable.
In my other G3 thats running Panther, I was upgrading the RAM and bent one of the processor pins on the logic board.
