Installing Service Pack 1 on your WSS3/MOSS2007 server(s)

First of all, you must backup SharePoint. Upgrading to SP1 should not break your WSS3/MOSS2007 install, but it's always better to be safe than sorry.

In my case we have 32-bit installation of SharePoint server, so these guidelines will refer to 32-bit version of SP1 for WSS3/MOSS2007, but as far as I know the guidelines can also be used for installation of SP1 on 64-bit instances of SharePoint server (just make sure you download 64-bit version of Service Pack file). You can download Service Pack 1 from Microsoft website (For MOSS installations, Service Pack 1 for both WSS3 and MOSS2007 must be installed):

1. Windows SharePoint Services 3.0 Service Pack 1 (27.3Mb)
2. Microsoft Office SharePoint Server 2007 Service Pack 1 (78.9Mb)

Now that you've backed up your SharePoint install and downloaded the updates, you're ready to install the service pack. First, let's install Service Pack 1 for WSS3:

1. Stop the World Wide Web Publishing Services
   1. Go to Start >> Administrative Tools >> Services
   2. Select World Wide Web Publishing Service and click Stop
2. Install the Windows SharePoint Services Service Pack 1
   1. Run the downloaded executable file WSS3 SP1 (wssv3sp1-kb936988-x86-fullfile-en-us.exe)
   2. Accept the licensing terms. Technically you should read the EULA terms before accepting, but nobody I know actually does it, so...
   3. Click Continue and click OK when prompted to remind the administrator to update all SharePoint servers.
   4. Click OK when the installation completes.
3. If you have MOSS2007 installed then skip SharePoint Configuration Wizard (i.e. close it, if prompted) and proceed to installing SP1 for MOSS 2007. If, however, you only have WSS3 installed, then run SharePoint Configuration Wizard, start World Wide Web Publishing Service and that's it.

Second, if you have MOSS2007, we need to install SP1 for MOSS2007:

1. Install the Microsoft Office SharePoint Server Service Pack 1
   1. Run the downloaded executable file (officeserver2007sp1-kb936984-x86-fullfile-en-us.exe)
   2. Accept the licensing terms. Technically you should read the EULA terms before accepting, but nobody I know actually does it, so...
   3. Click Continue and click OK when prompted to remind administrator that you update all SharePoint servers.
   4. Click OK when the installation completes.
2. Run SharePoint Configuration Wizard
   1. If SharePoint Configuration Wizard won't run automatically after SP1 install go to Start >> All Programs >> Microsoft Office Server >> SharePoint Product and Technologies Configuration Wizard
   2. Click Next at the Welcome screen and click Yes when prompted with the warning about restarting services
   3. Click Next at the Completing the SharePoint Product and Technologies Configuration Wizard and click OK when prompted to remind the administrator to update all SharePoint servers
   4. Go get a cup of coffee because the wizard might take a while to complete
   5. Click Finish after the configuration completed
3. Start World Wide Web Publishing Service to make your SharePoint server accessible by users again
   1. Go to Start >> Administrative Tools >> Services
   2. Select World Wide Web Publishing Service and click Start

If you want to make sure that you have successfully updated your WSS3 or MOSS2007 to Service Pack 1 you can do that through SharePoint Central Administration or Add/Remove Programs. To verify the SharePoint version through SharePoint Central Administration:

1. Open SharePoint Central Administration, go to Operations tab
2. Under Topologies and Services section click Servers in farm to list your SharePoint server(s)
3. If you see "Version: 12.0.0.6219" next to your SharePoint server, then you have successfully upgraded that server to Service Pack 1.

Alternatively, you can verify the SharePoint version through Add/Remove Programs in Control Panel:

1. Go to Start >> Control Panel >> Add/Remove Programs
2. Select Microsoft Office SharePoint Server and click on "Click here for support information"
3. If you see "Version: 12.0.0.6219", then you have successfully upgraded that server to Service Pack 1.

Please note that if you have multiple SharePoint Servers (WSS3 and/or MOSS2007) you need to update all of them to Service Pack 1!!!
