DCDiag functionality

DCDiag is one of those tools which is generally only used when things are going wrong, it can be very handy in finding directory services issues (which can manifest themselves in all kinds of ways….) Ned Pyle on the Directory Services team blog has written a brilliant post on this tool & what the various switches are actually doing for you, well worth a read (hopefully before you have to use it in anger): http://blogs.technet.com/b/askds/archive/2011/03/22/what-does-dcdiag-actually-do.aspx
