Take the 2-minute tour ×  For the purposes of running Active
Directory and DNS Server, what are the minimum memory
requirements for Server Core 2008 R2?  I've read of someone
using 256MB. This seems pretty low although summing up the
memory usage when running tasklist suggests it's OK.  Is there
any way to know?  share|improve this question WinPE 2.0 and
later requires a minimum of 256MB of RAM, any less and you won;t
be able to install windows. –  commandbreak Jun 16 '10 at 4:52

2008 R2 Core takes about 350 MB just to start. If you have a
smaller AD and DNS install you can easily fit it in 512MB
(without swapping going crazy). Anything smaller and you'll
pretty much be swapping non-stop.  share|improve this answer I

swapping like crazy ^^ I doubt it takes 350 MB to start, more
like 90-100 MB? It's not a big AD though. –  Oskar Duveborn Jun
