Microsoft has two information sharing and collaboration platforms for Windows Server 2003:
- Microsoft Windows SharePoint Services (WSS) is a free download for Windows Server 2003.
- Microsoft Office SharePoint Portal Server (SPS) builds on WSS to provide a fully featured collaboration platform.
Service pack 1 has been released for each of these platforms and is available from the Microsoft website (WSS, SPS). SPS SP1 requires WSS SP1 to have been installed. Once installed, neither of these updates can be removed.
Note that if multiple WSS servers are being used in a web farm, these should all be updated to SP1 at the same time as described in Microsoft knowledge base article 875358. For SPS, see Microsoft knowledge base article 875371.
