Each server in your server farm must include the regional language options to support the languages of all portal sites on that server.
Microsoft Office SharePoint Portal Server 2003 supports one language per server farm. The same language version of SharePoint Portal Server must be installed on all servers in the server farm.
All portal sites on the server farm must use the same language. However, other sites, such as SharePoint sites, can use different languages.
For more information, see Language Considerations for Microsoft Windows SharePoint Services.
When you upgrade to SharePoint Portal Server from SharePoint Portal Server 2001, you must upgrade your operating system to Microsoft Windows ServerĀ 2003. You must install the same language packs for Windows ServerĀ 2003 that were installed with your previous operating system.
