Hi, Is it possible to rollout SQL Server clustering without seperate active directory servers? My understanding was there was something called "domainlets" or similar and it should be possible to rollout a 2 node windows cluster on the same boxes. However, whilst we've got Windows Cluster Service running, SQL Server will not install saying it cannot install on a domain controller. Does anyone have any advice? Adding additional servers into the equation just for Active Directory seems overkill and very expensive (we are running a 4GB Blade solution). Any help greatly appreciated.
