conversely, i wouldn't run NT unless you have a savy NT admin either. 
Further, linux is probably easier and more secure to remotly administrate.

naturally more is always better, but if this is *just* a webserver, 
concentrate more on RAM than CPU cycles - that is, a pentiumII300 with 
1GB of RAM will kick the shit out of a PentiumIII 1Ghz 256MB RAM.

If you're really serious about things, you shouldn't even use Intel 
chips at all. AMD would be a better choice because of their large amount 
of L2 cache(typically 1Mb or more, whereas a pentiumIII only has 
256k-512k of L2 cache) which is the 2nd or 3rd biggest bottleneck on a 
webserver.  You could go with Intel Xeon chips which are basically 
pentiumIII's with more L2 cache, but they run a couple grand a chip, but 
I digress...

If its botha webserver and DB server, get as much as you can afford, 
with RAM being a priority over CPU cycles.

ya, cf4.51 service pack 2 is the latest in a series of buggy service 
packs from allaire.. *duck*  ;) (no harm meant Raymond)

if you're developing with cold fusion, theres no point in even having 
ASP 'turned on' if you go with NT/2000

a good open source alternative is Postgres. free and fast, its 
comparable to Oracle 7.2 in terms of stability and features.

if you have cash to burn, Oracle is always a clear choice.

i'd recommend keeping any kind of development code off your production 
server.. if you're co'lo'ing a server, you're somewhat serious about its 
performance and availability. running development code on a production 
box like that is counter-intuitive.

ask the provider how they're going to handle your backups. get *hard* 
details on this. also find out if they run off generators 100% of the 
time or are backed up by UPS units. also, DC or AC power? this will 
affect what kind of power supplies you get for the box.

umm.. disaster planning and procedures they have. what kind of physical 
access you have to the machine(most allow limited access, making remote 
managment a must)? do you have to schedule visits to the machine, and 
how far in advance? what kind of enviornmental control mechanisms do 
they have in place? what capacity is their generator(in terms of 
Kwatts/hour)? and how long can the generator stay running with on site 
fuel reserves?

umm....... what kind of network setup do they have? will you have your 
own subnet? switched network is assumed, at what 
speed?(100/10/1000Mbits) and what physical form? will you need 100BaseT 
network cards or something else? lots more questions i'm sure i could 
come up with, but those should do ya for now. :)
