To play around with SharePoint 2013 I need a decent setup of a Domain Controller, SQL Server 2012 and SharePoint 2013 Server. To achieve this I use Hyper-V and want to reuse as much as possible, but it has it limits…
Every machine, virtual of physical, has it’s own SID. This can be retrieved via PsGetSid.exe from Sysinternals.com. The thing is, it seems that the Domain Controller needs to have an unique SID within the domain. Although the domain members are allowed to have similar SIDs.
When I setup my topology I use a base image for every machine. Meaning these all have the same SID. After I installed my Domain Controller and second machine which I wanted to join to the domain I got this error “The domain join cannot be completed because the SID of the domain you attempted to join was identical to the SID of this machine”.
The solution to this is renewing the SID of the member machine. I needed to run sysprep.exe to change the SID of my base image, which I use to create the SQL Server 2012 and SharePoint 2013 machines. After running sysprep everything worked as expected!
