Today I troubleshooted an old DOS application that needed to run on a 32 bit Citrix XenApp Server. The last time I saw an actual DOS application in a production environment must be years ago.When starting the application,

Ntvdm Encountered A Hard Error Windows Server 2003 Sp2
some time troubleshooting I remembered a similar issue from a few years ago where a DOS application worked fine from the ntvdm encountered an illegal instruction windows 7 the Console but refused to work from an RDP or ICA session.And indeed the application works perfectly when run from the Console but not from a Console session. I noticed that the application switched https://support.microsoft.com/en-us/kb/937932 to full screen mode after it was launched (even when I set it to Windowed mode) and presumably this is why ntvdm errors: full-screen mode is disallowed for DOS apps in RDP (and ICA) sessions as documented in Q192190.I looked for a way to force the application to run in windowed mode but I was unable to find such a solution. So I decided to test the http://www.remkoweijnen.nl/blog/2011/12/14/ntvdm-encountered-a-hard-error/ application in DOSBox, an x86 PC emulator.And that worked perfectly, no changes were needed at all to make the application run.As an added bonus, DOSBox takes care of typical issues with DOS applications running on Citrix XenApp such as keyboard polling and 100% cpu usage.I was even more impressed that the application runs fine with DOSBox on my Windows 7 64 bit machine!There is one thing I didn't like though, DOSBox always shows a Splashscreen that fades in and out:This is typically something that is not desirable on a XenApp (or RDS) environment because it causes many unnecessary screen updates. This may be a non issue on a fast LAN but on a slower WAN or high latency connection it may matter. Do how do we get rid of it?There is no commandline argument or config setting that disables the splash so I figured that my only option would be to compile the DOSBox source and leave out the splash screen.So I downloaded the source files from the sourceforge project page and launched Visual Studio 2010.The Splashscreen is in sdlmain.cpp but I noticed this comment:C++ /* Please leave the Splash screen stuff in working order in DOSBox.

Whenever a 16bit application tries to run, windows throws this error. It is completely reproducible by running command.com.Has anyone experienced this problem and is ntvdm encountered there a workaround or fix?
