We have been receiving a few questions on whether or not Windows Server 2008 R2 SP1 can be installed on SBS 2011 and wanted to provide the definitive answer on this blog. Yes, it can and should be installed on SBS 2011 Standard. Please note that SBS 2011 Essentials already has SP1 installed out of the box.
A good rule of thumb is that if the patch or service pack is offered to your SBS server on Windows Update, it is supported to be installed on SBS. The SBS SE team reviews patches and service packs before they are offered to SBS servers.
If you download the service pack manually you may notice that it is listed as Windows Small Business Server 2011 Service Pack 1. This is normal. Windows Small Business Server 2011 Service Pack 1 == Windows Server 2008 R2 Service Pack 1.
Please be sure to back up your server before installing any update.
I have noticed that Windows Server 2008 SP1 is being offered in WSUS however on approving its only showing up on the member server and not the SBS 2011 server. How do I manually download it? Could someone pls share the URL? Thanks
