We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SUMMARY
This article describes how to upgrade from Microsoft Windows NT Server Internet Information Server (IIS) 4.0 to Microsoft Windows 2000 Internet Information Services (IIS) 5.0.

Requirements
The minimum requirements for IIS 5.0 closely match the requirements for Microsoft Windows 2000 Professional, Microsoft Windows 2000 Server, and Microsoft Windows 2000 Advanced Server. Although the hardware requirements for IIS 5.0 depend heavily on the amount of traffic that the server will experience, the following system hardware should meet the needs of most environments:
- Processor: 400 MHz Pentium II (or faster)
- RAM: 128 MB (or more)
- Connection: 100MB/Sec. Network Card
- Drive: SCSI Single Drive or SCSI Array
Important: Microsoft highly recommends that you replicate the server's Web site content and configuration settings to another server before you upgrade your Web server.

Back up the IIS Metabase
Before you upgrade the Web server with Windows 2000 Server, back up the IIS metabase file. To back up the IIS metabase:
- In the IIS management console, right-click the server name (for example, in the Internet Information Server folder: *mywebserver), and then click Backup/Restore Configuration.
- Click Create Backup.
- In the Configuration Backup Name text box, type a name for the backup, and then click OK.
For information on how to create a backup of the metabase for IIS 4.0, see the "References" section of this article, which contains a URL link to detailed instructions.
NOTE: When you backup the metabase, a file is created with the name <backup_name>.md0 (the last character in the extension is a zero; not the letter O). The file is stored in the %SystemRoot%\System32\Inetsrv\Iis.msc folder.
Data Recovery Recommendations
Best practice dictates that you ensure that all critical data is backed up to either a remote share or tape prior to the upgrade. This should include the metabase backup file that you just created and stored in the %SystemRoot%\System32\Inetsrv\Iis.msc folder, as well as all Web content.

Upgrade the Operating System to Windows 2000 Server
- Insert the Windows 2000 compact disc into the CD-ROM drive. If AutoPlay is enabled, the Windows 2000 Setup Wizard should start. If not, run Setup.exe from the CD-ROM drive.
- Click Upgrade to Windows 2000, click Next, and then follow the instructions provided by the Windows 2000 Setup Wizard.
By default, IIS 5.0 installs during the installation of Windows 2000 Server and Windows 2000 Advanced Server. When you upgrade from Windows NT Server 4.0 to Windows 2000, IIS 4.0 is automatically upgraded to 5.0.
NOTES:
- IIS 5.0 files are copied into the INETSRV folder. Existing IIS 4.0 files are overwritten.
- IIS 5.0 uses the existing IIS 4.0 metabase file. All configuration options from IIS 4.0 are left in place. IIS 5.0 sets default values in the metabase for new features that are included in IIS 5.0, such as World Wide Web Distributed Authoring and Versioning (WebDAV) and HTTP Compression.
- IIS 5.0 uses the existing IIS 4.0 IUSR_<computername> and IWAM_<computername> accounts.
Troubleshooting
Unlike IIS 4.0, which allows you to specify the location of the Web and FTP root folders, Windows 2000 automatically places everything in the Inetpub folder on the system drive. The only way to install IIS 5.0 on a different drive is to perform an unattended installation. For information about unattended installations, see the Microsoft Knowledge Base article, Q259671 "How to Change the Default Installation Paths for FTP and the Web" (listed in the "References" section of this article), the Deployment Planning Guide in the Windows 2000 Resource Kit, and the "Microsoft Windows 2000 Guide to Unattended Setup" (Unattend.doc), which is located in the Support\Tools\Deploy.cab folder on the Windows 2000 CD-ROM.
