DC/GC choice in exchange deployment

[derf238]

I’d like some input on dc/server role placement.
Company has two locations. Location A has 25 users location B has. 15. There is a point to point t1 between Loc A nd Loc B, and a T1 to the inter net from Loc A. Location B will not have a server. Location A will have a Win2003 Terminal Server, a Win2003 server for applications (including entire business management system used by all users all the time) and an Exchange 2003 server. All location B users will access applications, internet and email via Terminal Server.
Which server(s) should be DC, GC, DNS and other roles?
Server specs:
Exchange – dual processor, 2gb RAM, separate drive sets for OS and database
TS - dual processor, 2gb RAM
Application – single processor 1gb RAM

Second question – Exchange server –drive set 1 is mirror on array controller, drive set 2 is Raid 5. Which should have OS and which should have exchange databases?

I have reasons for various solutions on this, looking for some objective viewpoints.
Thanks in advance for your help

I wouldn't put full TS on a DC if you can possibly avoid it. Although you will have to install the licensing service there.

It's not really recommended but since you have so few users I'd put the DC etc. on the Exchange box.

Putting all the FSMO roles on a GC is contra-indicated but if you only have one domain and one DC there is not a lot you can do about it. If I remember correctly it is infrastructure master that can get confused when on a GC which shouldn't be an issue.

2nd question
OS should be on RAID 1, as should XC log files where possible.
RAID5 for the databases.
