Installing IIS 6.0
Planning for IIS 6 Deployment
Before you can deploy IIS 6 Web servers within your enterprise, you first need to install Windows Server 2003 or upgrade to Windows Server 2003. Only after Windows Server 2003 is deployed, are you able to install IIS 6 in your environment. Therefore, the majority of planning activities for an IIS 6 installation involves planning for, and deploying the underlying Windows Server 2003 operating system (OS).
There are a few ways to install Windows Server 2003, and therefore IIS 6 in your network. For instance, you could use the Windows Server 2003 product CD, use Microsoft Systems Management Server, install from a network distribution point, or install via disk imaging with Sysprep.exe and Sysprep.inf. Before installing Windows Server 2003 (IIS 6), you need to determine which deployment method suits your current situation. In addition to deciding on a deployment method, a number of planning issues or considerations needs to be addressed with regard to deploying Web servers within your network. This is true for both upgrades and clean installations.
The factors that should be addressed when planning deployment of your Web servers are listed below:
- Determine the Windows Server 2003 Edition to deploy.
- Determine whether a clean installation or an upgrade should be performed.
- Determine which backups should be performed so that if necessary, you can rollback the upgrade.
- Address any hardware issues, networking issues, licensing issues, and security needs.
The manner in which you handle and address the before mentioned issues, are greatly impacted by the specific Web server configuration you want to implement, and what your current situation is. A few scenarios are illustrated below, and could be specific to what you need to achieve, or what your current situation is:
- Upgrading each server running Windows NT or Windows 2000 to Windows Server 2003.
- Upgrading existing IIS 4 or IIS 5 Web servers to IIS 6.
- Whether the deployment would take place once off, or in stages.
- Whether you have a workgroup security mode, or a domain based security model.
- Whether Active Directory is already deployed or not.
When deciding on which Windows Server 2003 edition to deploy, incorporate the factors listed below:
- Understand the features available with each Windows Server 2003 Edition. Some features, such as using Active Directory or Cluster Services, are not available features of all Windows Server 2003 Editions.
- Determine the hardware requirements of the Windows Server 2003 Edition which you want to deploy. Each Windows Server 2003 Edition has its own individual hardware requirements.
- If you are currently running Windows NT or Windows 2000, you need to determine which upgrade path exists to the Windows Server 2003 Edition that you want to deploy.
As with any deployment, deploying IIS 6 has several issues and requirements that need to be addressed. To ensure that you encompass, and address all deployment specific issues and requirements, you should formulate a deployment plan. At a high level, a typical deployment plan includes the following stages:
- Determine what upgrade you need to perform, and how you are going to perform the upgrade (once off, in stages).
- Design your systems to suit the deployment you want to implement, while including requirements of the business.
- Thoroughly test your system design.
- Perform the actual live deployment. Test your end result.
An expansion of the deployment plan would include the factors listed below.
- Your deployment plan should be documented, and should detail clear objectives. Each person in the deployment team should be allocated with specific responsibilities.
- Investigate and document your existing network, in respective of:
- Hardware and software.
- Roles, security groups, users, and permissions.
- When deciding on a deployment method, select a method suited with your business requirements, and existing resources.
- Establish a testing environment, or test lab that closely mirrors your production environment, with respect to hardware, software, typical user permissions, expected traffic load, and so forth.
- When testing your implementation, test for both hardware and software compatibility. Document the results of each test phase.
- Plan to test after production deployment has occurred.
A few deployment tools that you can use to install IIS 6 are listed below:
- Windows Server 2003 product CD: The Windows Server 2003 CD can be used to install and upgrade to IIS 6. This CD also comes in handy when you need to use the Recovery Console or Automated System Recovery to repair corrupted OS files. If you want to install IIS 6 over the network, you would need to copy the installation files from the Windows Server 2003 CD to the shared distribution point.
- Setup.exe: Setup.exe is included on the Windows Server 2003 product CD, and is used to upgrade Windows NT 4 Server or Windows 2000 Server to Windows Server 2003.
- Setupmgr.exe (Setup Manager): Setup Manager is used to create the answer files for the automated unattended installation method. If you want to perform the installation over the network, Setup Manager can be used to create a distribution point.
- Unattend.txt: Unattend.txt is an answer file, and can be used to automatically answer the Windows Server 2003 Setup prompts.
- Sysprep (Windows System Preparation): Used in the disk imaging installation method, to prepare the disk for imaging.
- Cmdlines.txt, used when deploying Windows Server 2003 through disk imaging.
There are both manual deployment methods and automated deployments for installing Windows Server 2003, and thus IIS 6.
To install Windows Server 2003 and IIS 6 manually, an administrator has to be present when the actual installation is performed. The deployment methods common to a manual deployment of Windows Server 2003 are:
- Upgrade to Windows Server 2003 using the Windows Server 2003 product CD: This deployment method involves using the Windows Server 2003 CD, inserting it directly in the CD-ROM drive, and following the prompts of the installation wizard.
- You can alternatively perform the upgrade over the network. This involves copying the Windows Server 2003 CD to a shared network folder, called a distribution point.
- You can also use a self created custom bootable CD. The Windows Preinstallation Environment (WinPE) tools are used to create the CD that you can then use to perform a custom manual deployment.
The deployment methods common to an automated deployment of Windows Server 2003 are:
- Perform an unattended installation of Windows Server 2003: This deployment method can only be used for clean installations of Windows Server 2003, and therefore IIS 6. For an unattended installation, you need to create an answer file, which basically answers all the prompts of the Setup program. To create an answer text file,
- Use the Setup Manager tool, Setupmgr.exe, included in the Support Tools folder of the Windows Server 2003 CD.
- Use the unattend.txt file in the I386 folder of Windows Server 2003 CD, and customize it.
- Another automated deployment method which you can use is Remote Installation Services (RIS). RIS can be used for server and client machines, and particularly for mass deployments.
- You can also use Microsoft Systems Management Server (SMS)to deploy IIS 6 Web servers. It can be used to pgrade both Windows NT and Windows 2000 servers to Windows Server 2003. You can also distribute updates and patches through SMS.
- The disk imaging method can be used as an automated method for deploying any edition of Windows Server 2003. Disk imaging is best suited when you have a large number of quite similar hardware and software, and you want to perform a fast deployment. The requirements of a disk imaging deployment are:
- A disk imaging program.
- The Windows System Preparation tool, Sysprep.exe.
The steps common to disk imaging deployment are:
- Install a system which has the same operating system and configurations which you want to copy.
- Run the Windows System Preparation tool, Sysprep.exe, on the system. This is to prepare the disk for imaging.
- Use the disk imaging program or tool to create an image of the disk which you prepared using Sysprep.exe.
- Copy the image to the appropriate machines. You can burn the image to CD or you can copy it to a network distribution point.
Common IIS 6 Planning Issues
A few IIS 6 specific considerations that should be thought through are discussed in the subsequent section of this Article. IIS 6 has to be manually installed after you installed Windows Server 2003. This statement is true for Windows Server 2003 Standard Edition, Windows Server 2003 Enterprise Edition, and Windows Server 2003 Datacenter Edition. The only Windows Server 2003 Edition that automatically enables IIS 6 is the Web Edition. When upgrading existing IIS 4 or IIS 5 Web servers to Windows Server 2003, both IIS 4 and IIS 5 are however automatically upgraded to IIS 6.
After Windows Server 2003 is installed, for all editions of Windows Server 2003 other than the Web Edition, you can install IIS 6 by using one of the methods listed below:
- You can install IIS 6 from the Configure Your Server Wizard. When you first log on after Windows Server 2003 is installed, the Manage Your Server Wizard is initiated. To start the Configure Your Server Wizard, choose the Add Or Remove A Role link. You next have to follow the prompts of the Configure Your Server Wizard to install the Application Server (IIS, ASP.NET) option, and select or disable IIS components.
- You can alternatively use Add/Remove Programs of Control Panel to manually select the IIS 6 components that you want to install. To do this, click Start, Control Panel, Add/Remove Programs, Add/Remove Windows Components, and click Application Server. Select the Details button, and specify the IIS 6 components for the installation.
- For automated installation, include IIS 6 in the answer text file.
Because IIS 6 installs in locked down mode by default, you manually have to enable certain configuration settings so that ASP.NET applications can function properly. You can do this via the Web Service Extensions (WSE) node in the IIS Manager console tree. As part of your planning phase, determine which configuration settings you need to enable so that applications can perform properly, and be available to clients.
When upgrading from IIS 5 to IIS 6, test that any user developed applications which were developed for IIS 5 operate correctly on IIS 6. As part of your planning, test that your IIS 5 applications function correctly when run in the worker process isolation mode. This is the preferred application mode in IIS 6. You might though need to run applications that do not function properly in IIS 5 isolation mode on IIS 6.
- When upgrading from IIS 4 or IIS 5 to IIS 6, the default application mode is IIS 5 isolation mode.
- When a clean installation is performed, the default application mode is worker process isolation mode.
A few other factors to consider and that should be addressed when planning for IIS 6 are listed below:
- To Develop and run dynamic web applications, you have to manually install ASP.NET components after IIS 6 is installed.
- To have users manage content on the Web server through Microsoft FrontPage, you have to manually install FrontPage Server Extensions.
- To use sample web applications and scripts, you have to manually install them.
How to install IIS 6 using the Configure Your Server Wizard
After Windows Server 2003 Setup has completed, when you first log on to the machine, you are presented with the Manage Your Server Wizard. Before selecting to use the Wizard, if prompted, you can select to change display settings, screen resolution, and color depth settings. You could also be prompted to activate Windows Server 2003. Nonetheless, you can select the Manage Your Server Wizard to navigate to, and launch the Configure the Server Wizard to install IIS 6.
The directories listed below are created during the installation of IIS 6:

How to install Windows Server 2003 Web Edition over the network (clean install)
To install Windows Server 2003 Web Edition from a network distribution point, you would first have to copy all the necessary installation source files for the Web Edition to the particular network distribution point. To perform a clean install of the Web Edition, you have to create a network boot disk so that you can boot the machine from a floppy, and connect to the shared network distribution point. You would then have to run Winnt32.exe to perform the actual installation.
As mentioned, your first task is to create a shared distribution point before you can install Windows Server 2003 Web Edition over the network. You can do this by inserting Windows Server 2003 Web Edition CD in the CD-ROM drive of a file server, copying the I386 folder (including its content) to the hard drive, and then sharing the folder.
The next step is to create the network boot disk from which you will boot the target machine. After you created the network boot disk, insert it into the target machine. Proceed to specify the necessary password of the Administrator account for the file server on which the shared distribution point resides. After a connection is established with the distribution point; the Text Mode component of Windows Server 2003 Setup initiates. The installation files are then copied to the hard drive of the target machine.
After restarting the machine, you can choose that Windows Server 2003 be installed on an NTFS partition. The GUI mode component of Windows Server 2003 Setup starts after another restart.
