[THIN] Re: DOS program not working in Citrix

I went ahead and renamed the executables listed in that article and also
disabled os2 in the registry.  It is still hanging at os2.exe.  

Time to turn off hyper-threading like I have been asking the Citrix
admin to do for almost a year now.

Any other suggestions are welcome.

But did NTVDM.EXE get affinity set to a single CPU ?  If so, it's
possibly
not an affinity issue !  What exactly does the app do ?

I tried Marks Affinity Engine on both NTVDM and OS2.exe but the program
still hung at c:\WINNT\System32\OS2.exe on the cmd prompt window.

Any other suggestions or am I screwed?

I'm only remembering it from architectural courses from yay-back ;-)

As to 2003, I'm guessing that it's now incorporated within something
else? Either that, or the support has been dropped.
