The purpose of this chapter is to acquaint ourselves with the Windows Server 2003 family and then take a look at administration in Server 2003. So first we will discuss the Server 2003 family in other words the different editions that we have to work with. Then we will take a look at the logging on box and the security dialog box. Then we will take a look at the installing and configuring administrative tools. And then finally we will look at creating user accounts, computer accounts and organizational units. So let us take a look at this Server 2003 family first. First there is the web server and the web server can have two processors, and two gigabyte worth of memory that cannot be a domain controller. I would mark that down both for real life as well as for the test. That is a good thing to know that the web server is not assigned to be a in domain control and in fact cannot be a domain controller. It does not have clustering support. We will talk about clustering here in just a minute. But it does not have clustering support and it does not have 64 bit support. The standard server can have four processors; four gigabytes worth of memory can be a domain controller and is recommended to be a domain controller in small organizations or in small parts of a large organization. Does not have clustering support, it does not have 64 bit support. Enterprise Server can have 8 processors symmetrically multi processing which means that we can determine what those processors are doing. It can have 32 Giga bytes worth of memory and around and 64 gigabytes if you are using 64 bit support. It is designed to be a domain controller in a medium to a large size environment and it can have clustering support. Clustering support is when we have one database that can be accessed by multiple computers. The computers are then called head nodes. The purpose of this is to have fault tolerance in the entire computer. We can have fault tolerance in just about everything else on a computer except for the motherboard. If the motherboard fries then we do not have a server any more. That server will fail. But if we have another server that can also access the same database then we actually have fault tolerance on the entire computer system. That is what clustering is all about. The Enterprise Server can have 8 nodes cluster. Now a 8 nodes cluster would be very unusual, be very expensive both hardware as well as for the licenses, and it would only be in the case of a life and death situation. For example, may be a huge hospital organization, might have an 8 node cluster because we need to be able to get to that information no matter what. Those are the type of situations very very high security, high reliability environments and knowing that it is going to be extremely expensive. Enterprise can have 64 bit support. 64 bit support happens from reinstall special versionly operating system. but it better be on a big bad box. Because basically what it does is opens up a path power that is 64 bit wide instead of normal 32 bit, path power which allows a lot of things to happen very fast. But the chain is only as strong as its weakest link. So if you are going to have 64 bits support and we better have a multiple processor environment better have basically a big bad box that really has a tremendous need, a tremendous use in order to even worry about 64 bit support. Data Centre Server. Data Centre Server cannot be purchased at the store. The Data Centre Server Is designed by Microsoft, the company would choose a vendor and then the design team, that Microsoft would help out with putting the software in and testing it out, making sure that all works. Data Centre Server is a whole different world. We have 32 processors symmetrically multi processing and 64 processors with 64 bit support. We are going to have 64 gigabytes worth of memory and 512 gigabytes worth of memory with 64 bit support. Just an unheard of amount of memory. It is designed of course to be a domain controller and it is also designed, to be a power server for huge database environment as 8 node clustering support and then of course can have 64 bit support. So that is the Windows Server 2003 family. In our next section we will take a look at the log on box to get on to Server 2003 and the security dialog box. That is next.
