Add Role AD DS fails
Using the Server Manager to install AD DS, fails with error:0x800f0831. I can add DHCP role as a test that worked fine. and removed it also fine.
Have tried Reboots etc. All fully patched apart from Nov2014 Rollup package. No other roles or soiftware running. machine is on an existing domain with no errors.
I have also installed Net Framework 3.5, as I suspected the error may be indicating that was needed. It installed fine but no change in adding the AD DS role still fails exactly the same (about 75% of the blue bar)
