A Process to Remove and Reinstall Windows NT Option Pack, Proxy Server 2.0, and the Small Business Server 4.5 Console (279132)

MORE INFORMATION

In some situations, Internet Information Services (IIS) 4.0 must be removed and reinstalled. This process requires the removal and reinstallation of the Windows NT 4.0 Option Pack. Also, the components in Small Business Server 4.5 that depend on the Option Pack: Proxy Server 2.0, Outlook Web Access, and the Small Business Server console, have to be reinstalled.

The following process can be used to remove and to reinstall the Windows NT Option Pack and all the components that are dependent upon it:

1. Backup any custom Web sites that are hosted on the server.
   
   NOTE: When you remove the NT Option Pack, you also remove any Web sites that are hosted on the server.
2. Stop all the Proxy services in the Services tool of Control Panel. Use the Add/ Remove programs tool to uninstall Proxy Server 2.0. Verify that Proxy has been completely removed by using the instructions in the following article:

3. Remove Windows NT Option Pack by running the Setup.exe program from F:\Ntoptpak\En\x86\Winnt.srv, where F: is Small Business Server CD-ROM #2. When you are prompted, click Remove All. Verify that the file Metabase.bin has been deleted from your hard drive.
4. Restart the server.
5. Use the Small Business Server Setup program to reinstall Windows NT Option Pack and Proxy Server, as well as all dependencies (for example, Microsoft Data Access Components [MDAC], Active Directory Service Interfaces [ADSI], and Microsoft Management Console [MMC]). Do not restart the server at this time if you have Windows NT 4.0 Service Pack 5 or later on your system. Your system may become unstable if you do not reapply the current Service Pack.
   
   NOTE: During the installation, you may notice that hard drive activity drops to near zero and the progress bar stops moving for an extended period. Check for the presence of a new window which may have opened behind the primary window prompting for permission to replace a newer file. The new window may be accessed from the task bar.

9. If the server is hosting any additional Web sites, restore the Web sites that you backed up in step 1. If you did not back up the Web sites, you must recreate them.
10. Run the Internet Connection Wizard (ICW) to configure the Proxy server settings and establish the default packet filters. Additional packet filters can be created in the Internet Service Manager.
11. The ICW will enable access control by default, though only the Administrator account will be granted access to the Internet. Use the Small Business Server console to grant users access to the Internet.
