Before you deploy exchange 2003 you need to understand two things….
· First you need to understand what you already have in your environment.
· Second you need to understand the journey that you going to take darning the exchange installation.
So let’s start to understand what you have at your environment:
The first thing you need to do is to understand what you have in your environment, the best way for my understand is to put things on paper, create a document on what you already have at your environment.
The document should contain the following:
· The infrastructure of your environment – in this tab you will create documentation of you physical environment ,put on paper the offices physical place and which servers they include ,also describe which services those servers contain(Dhcp \ Dns \ Printer Server and more…), your ip segments and your type of connection between your branches and to the internet .
· Which model do you want …?
You are the “GOD” (The Admin that Control!!!!), so you need to chose how you going to take control on your exchange, ask yourself…… I’m the only one that controls all the exchange servers in the org…? Or I want to delegate few features to my “Lower” admin in other branches so I reduce my work on the mail servers. It’s very important to understand it because when you install the exchange it’s the only time that you can chose your administrative group configuration.
· AD structure – understand your domain controllers deployment , because exchange server goes hand to hand with your AD you must know how much DC you have ,how much sites…? And do you have more than one forest…?
· How you handle the mail flow till now…? Are you going to update existing mail servers or you wanted to install new exchange and create migration between them?
After you understand what you have and what you want to do we can go to our journey to choose the right way to do it?
· As you know here you also need to choose the exchange version to buy and install.
In exchange 2003 we have 2 versions:
Standard Edition – here we have to understand the main difference, the standard version can do almost all the things that her big brother (Enterprise Edition) but with capacity limits.
Supports only one mailbox store and Public store of 16 GB.
(We can increase it to75GB after installing SP2).
Support up to 20 stores with no capacity limits.
But what is important to understand is that exchange 2003 standard doesn’t support
High-Availability because you cannot create clustering!!!!
About the hardware just checks at Microsoft site because it’s simple to find it out.
The other requirements that you need to apply before installing the exchange (It’s important to understand it because it’s really different at Exchange 2007 but this will be on other post):
1. Verify that you have full Microsoft update include Net framework 2.0 or above.
2. Install ASP.NET.
3. WWW – world wide web publishing
4. SMTP and NNTP.
After you complete to install and configured all of the above we need to update and tell our lovely “SCHEMA” that we have a new kid with different attributes, for doing that we need to run Forest Prep and Domain Prep:
Here we extends the active directory schema and create new objects and classes, because the schema replicated to all domain controllers we need to run forest prep only one time.
To be enabling to run forestprep you need to be a “Schema Admin” and “Enterprise Admin”.
To install forestprep follow the next steps:
1. Open run-> Cmd
2. Type : cd:\setup.exe /forestprep
3. Just click next until the update finish.
When we run this command we will create 2 new groups in the Active Directory:
· Exchange Domain Servers.
· Exchange Enterprise Servers.
To run this command we need to be in the domain admins group and also run it at our root domain.
To install domianprep follow the next steps:
4. Open run-> Cmd
5. Type : cd:\setup.exe /domainprep
6. Just click next until the update finish.
