A foreground process under Terminal Services is per session - the "topmost"
window for each user.  Everything else is background.

Subject: [THIN] thread quanta and chkroot.cmd thingy

chaps, I have a memory like a seive,

could somone please remind me of what chkroot.cmd's function in life
is..
calls chkroot2 which determines if the Root drive has been set and is
mapping to the homedir

also, for you performance tuning bods out there... I have a question
about
the basic performance setting in windows 2k.. I read in the Metaframe
tuning
guide by the guy from Citrix that it is recommended that the performance
setting in win2k be set to background processing in order to provide
equal
thread quantum for all process priorities, i.e. 20/20/20 or something
like
that..

well, I'm no expert but I would disagree with this because why would you
want to give equal priority to threads that have been specifically
programmed to execute in the background??  

There is a lot of discussion about this. The problem is which task is in
the background. That setting was made for a single headed machine that
differentiates between foreground and background easily. In a terminal
server the general argument is that the "foreground" is the last app
brought to the foreground across all sessions. Background gives
everything equal time across all sessions... Made sense to me even
though I have never tested it.  I am not sure but if Tim Mangan is
around he may have some insight into this that I do not.

I think also that a mistake is generally made where people describe
users
running on a terminal server as being 'background'... my guess is, that
this
is not correct either... just because they cannot be seen, they are
still
'foreground' applications in the context of the windows execution
environment.  This is a very basic setting and I would like to get it
right
for our standard farm server build as I have over 40 to build over the
next
few months ??

Any guidance appreciated....
