OK, I'm planning my companies brand new Windows 2003 AD domain with new servers and the whole 9 yards. Here is my question my company has >100 employees I plan on out sourcing Exchange. I was planning on ordering 2x DL360 G5 3.0Ghz 4GB of Ram 2x 72GB  SAS hard drives for the OS (mirror) & 2 72GB + 1 hot spare for AD database. Does this sounds about right for the sizeing of these two Active Directory controllers. Also should I setup the database on another drive besides the C:\ and just keep the c:\ for the OS and that's it??

I would consider 100 employees to be very light load therefore what your order is sufficient to me.
It's certainly a good idea to keep OS and database on seperate disks.

MS used to have AD sizing tool for w2k, that should give you a rough idea for w2k3 as well.

Looks good...

I would mirror the OS on the first set of SAS drives. (C:\)

I would mirror the second set of SAS drives to install the NTDS and AD portions. (D:\)

You shouldnt have to worry about space on D:.  We have about 5,000 users and our NTDS size is only around 10GB -- and that's HIGH! -- because we have to replicate the entire DoD GAL along with it.

Not bad - those servers should be sweet - they are overkill for AD but its always better to have more.....Why are you outsourcing exchange...those boxes could easily run it and it will be much cheaper for you

Thanks for the responces everyone. Jay_Jay70 to answer your questions about exchange. Usually I like to have my DC's left alone and just be DC's I like to have exchange be a seperate box totally. Also to buy Exchange 2007 STD would cost around $800 and 100 cal's would cost around $7,000. Not to mentions AV software and backup software and spam filtering. Plus it is one more mission critical server to deal with. I have been looking at the following hosting company http://www.mailstreet.com/ they do exchange hosting and even offer Blackberry and sharepoint services.
