Designed for exchanging information within a company and saving it server-side (e.g. Outlook, OWA, IMAP, PDA).

6. Presented by Ben Serebin www.reefsolutions.com The Required Specs Slide Exchange 2003 comes in 2 version levels, Standard (S) and Enterprise (E). E has all the features of S, but many limits are eliminated and clustering requires E. E is designed for larger installations. Exchange Requirements: P133, Win 2000 Srv, 256MB, 500MB on Exchange install partition, 200MB on System partition (these are unacceptable requirements, and I would NEVER run Exchange on this.)

7. Presented by Ben Serebin www.reefsolutions.com The Exchange Servers I Buy If a company is going to run Exchange, here are the minimums I would recommend on a server: Pentium 4 1GB of RAM RAID 1 or 5 (2 or 3 HDs at min) 50GB of storage Antivirus is a requirement (current favorite is TrendMicro)

8. Presented by Ben Serebin www.reefsolutions.com Lets Get Exchange Running… Ideally install Exchange on a separate server from the DC. To get the most functionality, install on Windows Server 2003. Select Exchange Deployment Tools to get Exchange up and running.

9. Presented by Ben Serebin www.reefsolutions.com For those with 0, 1 or more… Microsoft made it a lot easier for Exchange 2003 installs since the installation is a step by step process.

10. Presented by Ben Serebin www.reefsolutions.com Are we in a sharing mood? For folks with an existing Windows Server environment, and no Exchange, 4 option is your pick. - Coexistence can be used for migration or backward compatibility - Make sure server is part of domain

11. Presented by Ben Serebin www.reefsolutions.com Check, Check, and Check Important -> DCDiag, NetDiag, ForestPrep, & DomainPrep

12. Presented by Ben Serebin www.reefsolutions.com For additional Servers, Same Checks minus ForestPrep

16. Presented by Ben Serebin www.reefsolutions.com Lets Talk Domain Name System (DNS) Install Exchange and your done. NO! Install Exchange and your done. NO!

Which DNS records are required? How do I configure the DNS records? How do I configure the DNS records?

17. Presented by Ben Serebin www.reefsolutions.com DNS is the answer. DNS Records are the yellow pages for servers to find each other. DNS Records are the yellow pages for servers to find each other. For email to work, 2 records are required. One A record and one MX record of a domain name (e.g. abc.com). An A record is called a host record which is used to translate a domain name to IP. And a MX record called a mail exchanger record to identify which A record is the mail server. For email to work, 2 records are required. One A record and one MX record of a domain name (e.g. abc.com). An A record is called a host record which is used to translate a domain name to IP.

18. Presented by Ben Serebin www.reefsolutions.com A + MX = Email A record configuration for abc.com: mail.abc.com 1.2.3.4 1.2.3.4 would your Exchange Servers public static IP. MX record configuration for abc.com: mail.abc.com 10 abc.com 10 is a relative number for priority. MX indicates host responsible for email.
