Ok, so I need to upgrade a Windows 2003 DC from mixed mode to Windows 2003 native mode. There is only one DC and there is no danger of any NT Servers being introduced to the forest.

I checked on AD how to raise the functionality but is there anything else I need to know? I’m doing the upgrade tonight and I have a full backup tape to hand if needed!

 

All done and all working ok, phew!

Just got a phone call from a remote user that can’t connect to the VPN and claims its because I changed the domain functionality. The VPN stops on the firewall so in theory I could take the DC out (the firewall is also set up for DHCP for VPN users) and the user could still connect. The phone call was fun.

Could I BE anymore stressed out? Probably not

 

I briefly had to deal with this a while ago when a NT domain was being migrated to 2k but nothing since.

It was a simple process and doesn’t even require a reboot (I rebooted anyways) but I always hate the “You cannot go back no matter what” changes
