Does anyone have any experience with the stability of DOS(NTVDM) sessions on Windows 2003 32-bit servers?
Our organization is migrating to Windows 2003 servers. We have an AREV 2.1 enterprise-wide client-server application, and we would like to run an instance of AREV directly on the server to monitor users' transactions, rather than our currrent practice of dedicating a PC to do the work.
For testing the migration of all enterprise applications, we have built a 32-bit Windows 2003 server with several VMWare instances. I log onto the VMWare session as Administrator and: (1) map a network drive to a share containing our data files on the same server and (2) use a shortcut to launch AREV, with memory parameters set to Conventional=Auto, EMS=4096, XMS=None(uses HMA), DPMI=Auto, and AREV is started with /X /M4096.
The NTVDM session is very unstable. AREV does not get very far before completely aborting the NTVDM session, or I get various "16 bit MS-DOS Subsytem" errors. Also, the Security Event Viewer records failures referring to requests for "Privileges: SeTcbPrivilege".

We have a few arev users (3.12 on XP) equiped with VMWare. Our Arev LH service is on Novell servers.
The Arev runs fine and is stable. The problem we have is that the CPU Plus doesn't work, and so the NTVDM/Arev session consumes just as much cpu cycles we have. So the users can't really run Arev and anything else on that computer. Other software is sluggish at best.
So the users connect to our terminal services arev from their VMWare computer, and avoid the problem.
