I ran two companies, one a start-up with half a dozen people, the other a division with around 100 employees. At the start-up the admin's PC was doing all the housekeeping, connecting us to the web, server for this, that and the other thing, and so on. NT4. I can't remember any downtime, ever. At the bigger place we had a server room and all that, of course. But even that was kept lean and servers were regular PCs, and only added as needed. One guy with a Harley Davidson ran IT all by himself. No downtime in years either. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

NT4 (and later versions) can work very reliably. No sweat. Just get reliable hardware like a Proliant or Dell server with ECC memory and make sure the drivers are OK and the software is compatible. Move anything that isn't working to a different machine/OS. In my experience trying to get too many different functions out of one Windows server is a world of pain. Just don't go there because Windows can't do that. Simply split the functionality over multiple machines and/or operating systems. I've setup/seen/maintained NT4 and Server2003 machines reaching uptimes of over a year without problems. Same goes for Linux BTW. Even at small companies I used to place a Windows server and a Linux server. Windows for file serving, Exchange and printing, Linux for security (firewall) and miscellaneous tasks. >20 people won't tax *anything* that heavily (well, SQL >queries might get pokey if you've got some big tables >and/or poor keys). Its not about load. Its about keeping a system going so you can sleep at night. Downtime costs a lot of money and causes aggrevation by users (bad for moral). It is very comforting for users to be able to rely on a system to just work. -- Failure does not prove something is impossible, failure simply indicates you are not using the right tools... nico(a)nctdevpuntnl (punt=.) --------------------------------------------------------------

The wax is liquified (melted) when the printer is turned on (i.e., it needs to "warm up"). Then, the liquid ink is "sprayed" onto the paper like an inkjet would (only different, of course :> ). When the printer is powered off, the unused ink resolidifies. They are expensive to operate (not just because an ink kit is pricey). In addition to the long warm up period, there is a cleaning cycle (which increases the warm up) which discards a boatload of "ink" each time you power up the printer. I.e., you don't use these for printing *a* page :-( (that's why the LJ6P is so wonderful -- though monochrome -- as I can turn it on and print 15 seconds later) |
