Can I install Windows Server 2003 Service Pack 1 (SP1) on Microsoft Small Business Server (SBS) 2003?

A. Although you can install the standard Windows 2003 SP1 on an SBS 2003 installation, it's best to use SBS 2003 SP1 (which will follow the standard Windows 2003 SP1 release by 60 days). Some users have experienced problems when installing SP1 on SBS 2003. If you've already installed SP1 on SBS 2003, I recommend that you uninstall it and install the SBS 2003-specific version. Here are a few caveats to remember if you do uninstall Windows 2003 SP1:

  • The Change Server IP Address tool will continue to fail after you uninstall Windows 2003 SP1. (The workaround for this problem is to remove Windows 2003 SP1, disable DHCP, and rerun the SBS 2003 Configure E-mail and Internet Connection Wizard--CEICW.)
  • Power Users retain SharePoint Administration privileges even after you change the role to Reader.
  • Reinstalling Microsoft Exchange Server fails.
  • Reinstalling the Intranet component fails.
  • Fax Services won't start, and the Fax Configuration Wizard won't run after you uninstall Windows 2003 SP1.
