Hopefully you can assist.  I have two DMZ networks. - windows 2008 r2 file server - workstation windows 7

Ports 139 and 445 are open.

My problem is i am not consistently able to connect to the file server.  Sometimes i'm able to map a network drive and sometimes i am able to browse the share.  It is not consistent.  Please assist.

    Do the machines in the DMZ use DNS registration for name resolution?  (Or at least static entries?)  WINS?  Or are you relying on NetBIOS broadcasts?
