Add BackConnectionHostNames to the registry via PowerShell

07/20/2010

PowerShell

Since it is a server thing and not a SharePoint thing, SP2010 will still have issues trying to hit a FQDN from the server. This means you may see weird errors in your crawl log for search. Many people simply disabled the loopback check to get around this. However, that is not the best resolution for production environments. To understand more on the reasoning behind this, you can check out this excellent post on the topic.

In that post you will see the steps on opening up the registry editor and combing through all the folders to find the desired location where you can create the BackConnectionHostNames property. Or, you can just wake up your new best friend, PowerShell, and fire off this line. Make sure to edit the Value parameter to include your environment’s host names.

New-ItemProperty HKLM:\System\CurrentControlSet\Control\Lsa\MSV1_0 -Name “BackConnectionHostNames” -Value “intranet.contoso.com”,”mysites.contoso.com” -PropertyType multistring

In order for this change to go into place, you need to restart the server. Again, just tell PowerShell to Restart-Computer and be done with it!

    Adam,

    Should this be done on all servers in the farm (2-2-2-1: WFE, CTRL ADM, SRCHIDX and DB SRV). On all SharePoint servers not DB Server?
