I have started looking after a small network of about 50 users, which has a server with windows 2003 standard and exchange 2003 standard edition. This server has all the roles i.e, file & print, DHCP, DNS, Email server, all roles of active directory etc.
We have another server as domain controller and we are using a software to replicate the data from main server to second server, however these are just plain file and folders . There is no exchange high availablity scenario etc.
The main server is an old HP machine and is out of warranty, however, second server is relatively newer than the main server. We plan to upgrade this but this will take time to research, get upgrade costs approved and rollout the upgrade.
In the mean while, i want to make sure i have some sort of backup plan if the server crashes.
I am planinng to install and share the printers on the second server.
Share the replicated folders on the second server. The batch file in Netlogon folder can be changed to point to this machine if needed when DR is invoked.
Can use ndtsUtil to grab all FSMO roles needed when DR is invoked.
We have many DHCP reservations on the main server. can these be backed up and restore to second server in DR scenario?
My biggest worry is exchange server, i have no idea how can i handle this. My initial thoughts are that i should install another server in the domain (domain controller/member) in such a way that i can install the exchange server immediately on that if needed and restore exchange on that. can anyone help me with this please. Please bear in mind that this will be done in case if main server completely dies so this new exchange sever will be become production server.
I will appreciate if you can guide me thorugh this and point out any other points that must be taken into account.
