Hardware and Software Requirements

Before you install SharePoint Portal Server, make sure that your computer meets the following recommended hardware and software requirements.

Server Requirements

The following are the requirements for each server running SharePoint Portal Server:

• Intel Pentium III–compatible processor minimum recommended.
• 256 megabytes (MB) minimum of RAM recommended.
• 550 MB minimum of available disk space. The drive must be formatted as NTFS file system.
• Microsoft Windows^® 2000 Server or Windows 2000 Advanced Server operating system, and Windows 2000 Service Pack 1 (SP1) or later.

  Installing SharePoint Portal Server on a system that has been upgraded from Microsoft Windows NT^® version 4 can cause install failures. It is recommended that you install SharePoint Portal Server on a clean Windows 2000 Server. If you are installing on a Windows 2000 system that was upgraded from Windows NT 4, manually register the Oledb32.dll file before installation to avoid installation failure. Go to the Program Files\Common Files\System\Ole DB folder and type regsvr32 oledb32.dll to register the file.

• Internet Information Services (IIS) 5.
• Simple Mail Transfer Protocol (SMTP) Service. This is a Windows 2000 Server component.

In addition to the requirements listed previously, install the following Windows 2000 updates before installing SharePoint Portal Server. These updates are available at http://support.microsoft.com/. These issues will be addressed in subsequent Windows 2000 service packs.

If you are installing on Windows 2000 Server with Service Pack 1, install the following updates:

• Windows 2000 Patch: Token Handle Leak in LSASS. Note that this new version of the hotfix replaces the previous hotfix (Q288861) release.

  For this hotfix, see Q291340: Token Handle Leak in LSASS Using Basic Authentication.

• Windows 2000 Patch: GetEffectiveRightsFromAcl Causes ERROR_NO_SUCH_DOMAIN. Addresses a problem that can cause subscription notifications to fail when the access control list (ACL) on a document contains a Domain global group.

  For this hotfix, see Q286360: GetEffectiveRightsFromAcl() Function Causes "ERROR_NO_SUCH_DOMAIN" Error Message.

If you are installing on Windows 2000 Server with Service Pack 2, install the following update:

• Windows 2000 Patch: Token Handle Leak in LSASS. Note that this new version of the hotfix replaces the previous hotfix (Q288861) release.

  For this hotfix, see Q291340: Token Handle Leak in LSASS Using Basic Authentication.

The following prerequisites must be met before installing SharePoint Portal Server:

• Windows 2000 Hot fix (Pre-SP2) Q269862 cannot be installed on the computer. If it is installed, remove it before installing SharePoint Portal Server.
• The Windows Remote Registry service must be running. This service is started by default.

To start the service manually:

1. On the taskbar, click Start, point to Programs, point to Administrative Tools, and then click Services.
2. Right-click Remote Registry Service, and then click Start.
   • IIS configuration: Ensure that World Wide Web Publishing Service (W3SVC/1), the Default Web Site in IIS, is started. SharePoint Portal Server setup performs a simple test to warn of potentially invalid IIS settings. This test checks the configuration of W3SVC/1 (the Default Web Site) to ensure that the Web Site Identification TCP Port is "80" with IP Address "(All unassigned)". If multiple entries were configured in Advanced Settings, setup checks only the first entry. Other configurations may be acceptable, as long as "localhost" on port "80" is a valid way to connect to W3SVC/1 (the Default Web Site) on the computer. If necessary, you can alter the configuration by opening Internet Services Manager under Administrative Tools and selecting Properties on the Default Web Site.
   • SharePoint Portal Server requires the Default Web Site in IIS to use port 80 as the TCP port for localhost. Before installing SharePoint Portal Server, ensure that you specify 80 as the TCP port. In addition, do not change the port to an alternative HTTP port (such as 8000 or 8080) after installation. Ensure that port 80 is specified and remains as the primary port for the server.

Coexistence Issues

The following software does not coexist with SharePoint Portal Server:

• Exchange 2000 Server
• Exchange 2000 Enterprise Server
• Exchange Server version 5.5 and earlier
• Microsoft Site Server (any version)
• Microsoft Office Server Extensions

SharePoint Portal Server setup checks for the existence of this software and fails if this software is already installed. If you install this software after installing SharePoint Portal Server, SharePoint Portal Server will stop functioning properly.

SharePoint Portal Server is not supported in a clustered environment. You cannot install SharePoint Portal Server in a clustered environment, and you must not add the server to a clustered environment.

SharePoint Portal Server and Microsoft SQL Server

If you install SharePoint Portal Server on a computer running SQL Server 7 or SQL Server 2000, SharePoint Portal Server upgrades the existing Microsoft Search (MSSearch) service. In addition, SharePoint Portal Server upgrades the full-text index format of all of the existing indexes on that computer the next time that MSSearch starts. For the upgrade to succeed, there must be enough disk space on the computer to accommodate 120 percent of the size of the largest full-text index on the drive. Upgrading the full-text index format can take several hours, depending on the number and size of the existing indexes. During the SharePoint Portal Server setup, a message informs you that the service will be upgraded.

Because SharePoint Portal Server upgrades MSSearch and full-text indexes, do not install SharePoint Portal Server on a server that participates in a SQL Server clustering environment or add a computer running SharePoint Portal Server to a clustered environment.

You can install SQL Server on a computer already running SharePoint Portal Server. In this instance, SQL Server uses MSSearch installed by SharePoint Portal Server. If you remove SharePoint Portal Server from a computer that has SQL Server installed, SharePoint Portal Server will not remove the upgraded MSSearch because it is a shared service with SQL Server.

SharePoint Portal Server and SharePoint Team Services

If SharePoint Team Services from Microsoft is installed on the computer on which you want to install SharePoint Portal Server, you must uninstall SharePoint Team Services before installing SharePoint Portal Server. In addition, you must delete the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Office\9.0\Web Server

Incorrectly editing the registry may severely damage your system. Back up the current version of the registry before making any changes. You should also back up any valued data on the computer.

If you install SharePoint Team Services after installing SharePoint Portal Server, you lose the following functionality from SharePoint Portal Server:

• Discussion items are not included in the index and are not available for search.
• You do not receive notifications for subscriptions to documents or folders in the work-space when you subscribe by using the Microsoft Office collaboration toolbar. The Office collaboration toolbar is available from both Office and Microsoft Internet Explorer.
• Subscriptions made by using the Office collaboration toolbar and all discussions are stored in SharePoint Team Services. These subscriptions and discussions are not backed up during the SharePoint Portal Server backup process.

Installing SharePoint Portal Server on a Domain Controller

If you install SharePoint Portal Server on a domain controller:

• There is no local Administrators group. Consequently, only users assigned to the coordinator role can specify security on folders. If a coordinator makes an error, there is no possibility for a local administrator to resolve security issues.
• You may need to restart the domain controller after installing SharePoint Portal Server.

Renaming a SharePoint Portal Server Computer

You can rename a SharePoint Portal Server computer at any time. After renaming the server, you must restart it. In addition, SharePoint Portal Server Administration installed by setup prompts for authentication and displays an error before opening, after you rename the server. To remedy this situation, manually add the SharePoint Portal Server snap-in to Microsoft Management Console (MMC).

Client Requirements

The following are the requirements for each computer running the client components of SharePoint Portal Server:

• Intel Pentium-compatible 200 megahertz (MHz) or higher processor recommended.
• 64 MB of RAM minimum recommended.
• 30 MB of available disk space on Windows 2000 systems; 50 MB of available disk space on all other systems.
• Windows 98, Windows Millennium Edition, Windows NT 4 with SP6A, or Windows 2000 Professional, Windows 2000 Server, or Windows 2000 Advanced Server. Coordinator functions require Windows 2000 Professional, Windows 2000 Server, or Windows 2000 Advanced Server.
• Internet Explorer 5 or later. Microsoft Visual Basic^® Scripting Edition (VBScript) support is required. This is included in the default installation of Internet Explorer 5.
• Microsoft Outlook^® Express version 5.01 or later.
• SharePoint Portal Server Office extensions require Office 2000 or later.

Dashboard Site Requirements

Accessing SharePoint Portal Server through the dashboard site does not require the user to install the client components. For the Windows operating system, you can use the following browsers:

• Internet Explorer 4.01 or later
• Netscape Navigator 4.51 or later (for Italian and Spanish versions of SharePoint Portal Server)
• Netscape Navigator 4.75 or later (for English, French, German, and Japanese versions of SharePoint Portal Server)

Macintosh and Solaris operating systems are not supported.

In addition, you must enable Microsoft JScript^® or Netscape JavaScript support in your browser for the dashboard site to function.

To use the dashboard site with Netscape Navigator, you must use Internet Services Manager to enable Basic authentication for the workspace node on the Default Web Site. To enable discussions to work when the browser is Netscape Navigator, you must also enable Basic authentication for the MSOffice node on the Default Web Site.
