Web hosting control panel - Part 3: Windows Server 2003 Upgrades and Migrations
Part 3: Windows Server 2003 Upgrades and Migrations Upgrading to Windows Server 2003 . Make a dword entry (the name is arbitrary) with a value of 1 in the following registry node: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW3SVC RetainW3SVCStatus . If performing an unattended installation, set DisableWebServiceOnUpgrade=false (in the [Internet Server] section of the Unattend.txt file). The following are also some baseline changes in security configuration: . Default is more restrictive The default security settings for new installations of Windows Server 2003 are more restrictive than Windows 2000 Server (or Windows NT 4). Windows Server 2003 Setup will, however, retain existing security settings during an upgrade (i.e., the existing security configuration will not be enhanced by upgrading). . Internet Explorer is more restrictive Internet Explorer is set up with an enhanced security configuration, which by default disables scripting, ActiveX controls, file downloading, and the browser virtual machine. Also, Internet zone security settings are set the same as Restricted zone, and by default all sites are assigned to the Internet zone. Pass-through authentication of user credentials is blocked outside of the Local Intranet zone. These Internet Explorer settings can be configured by using the Advanced tab of the Internet Options icon on Control Panel. . Downloading software updates Because of the security enhancements set in Internet Explorer, you might be unable to download software updates from the Internet until you add those sites to the Trusted zones. Verify an Upgrade Recovery Plan Because upgrade processes can and do err, verify that you have an effective recovery plan in place prior to commencing with an upgrade. Likewise, a migration can include removing information from the source domain; thus, prior to either an upgrade or migration, you should make sure that you have verified backups. You can create an image of the system partition prior to upgrading so that you can restore its original state quickly if needed. Verify the method of backup (network share, CD, DVD) and restoration (network connectivity, imaging software, drivers, etc.) before beginning an upgrade or migration. Create the Emergency Repair Disk in case the upgrade does not complete successfully. If you are upgrading an existing Windows 2000 domain or forest, the Active Directory schema information must be updated before you can begin. Run the Active Directory Preparation Wizard (Adprep.exe) with the /Forestprep parameter to upgrade the forest data and with the /Domainprep parameter to upgrade the domain information. Normally, this process is successful, but it can fail, and, worst case, it can render the domain controller inoperative. To ensure that you can recover from such disasters, you should do a full backup of two domain controllers from each domain in the forest before running the ADPREP /FORESTPREP command and verify the backup media.
