Here at work, we still use RH9.0 on production servers that go into the
field (not broke, dont fix it). If we ever need to do a major update due to hardware limitations or similar... and a new distro makes sense, it'll be CentOS (gotta love being the top of decision making hehehe)... it's been rock solid on my remote machines (other than the poor 4.x box heh).
I suppose you are still running Windows 95 on desktops?
ROFL. No :). 95 *is* broken :). We have a mix of Win98 (two systems, for some stubborn legacy software), Slackware 12, Win2K Pro, 2K Server, 2K Advanced Server, 2003 Server Enterprise, and XP Pro. I don't believe we have a Vista system anywhere yet.
99% of our workstation/desktops need Windows for either development or artsy tools. We have a couple odd Windows based servers for some Windows software we have to communicate with in the field (gotta have local testing!). Anything that handles a 'server' aspect in house is Slack. 3 or 4 years ago, I used to Slack + vmware... but... that was clumsy at best.
For the next distro on remote servers, CentOS will definitely be my choice (being most similar to existing layout). Here in house, I might switch over to it as well during next upgrade bunch... just so that there's a cohesive layout between field and in house systems. I've just been a die hard Slack fan for about 12 years, and it's hard to let go hehehe :). I've had some flexibility in that I'm the only linux-admin in house... but... that needs to change soon, I've got too many responsibilities. CentOS seems like a perfect and natural progression. It's been a breeze to administer remotely in a non-work environment, and breeds familiarity with the RH9 servers.
