I have the same problem with Windows Server 2008 (not R2) on one of my machines. I posted about it here before, but never found a solution. The command line tool works fine, so I just use that instead.Has anyone seen any strange behavior with the ArcHTTP software and Windows 2012?
My 1882 card keeps disappearing from ArcHTTP (i.e. it's no longer listed under SAS RAID controllers section) after about a day of uptime.
