I haven't tried to use EMS in Vista because I've been using DosBox
exclusively since 2003. I do know that the no ems problem in NT4/2K/XP/
2003 was caused by integrated hardware eating up the memory addresses
that NTVDM was trying to use to allocate EMS and since Windows is
being conservative with where you can map memory addresses then the
only way around this is to either disable the hardware that is eating
those memory ranges or to modify the Windows registry to remap the
addresses.

Here's one of many threads on the issue @ VOGONS:
