UAC DayZ has been released with everything needed to run your own server locally for single player, LAN or internet. Server files are built with DayZ Control Center 5.9.2.0, so all credit goes to Crosire and his collaborators cool software. My server on gameservers.com is actually running off of this. Can download from Uacdayz.scoredoom.com Moddb download link will follow shortly.
The manual install steps have been tested on multiple machines, and if there are problems, you will need to make sure that steam/Arma2/Arma2OA and supporting mods are installed properly, and that you have permissions and other environmental effects like local firewalls or anti-virus looked at as well. Tested on XP and Windows 7. Windows 8 & Windows 10 should work.
Currently you join the local server or other servers through .bat files provided in the archive. Will look into dayzlauncher support. I tried Dayzlauncher and it has mods 'hardcoded' into it from first glance, rather than dynamically checking addons/mods in arma2 oa folder.
Fixed a bug that would not allow an important mission to complete. You will also need to install this patch as well: Mediafire.com
