Installation of applications while user are logged on.

[FrankY]

Hi, i know that application must be installed while users a logged off and in
install mode.

Question 1: im i right or there is a way to install apps any-time on a
terminal RDP production server ?

Question 2: do windows updates (as well as office update) need to be install
in "installation mode" ?

Thank's

Yes.

If they are installed via Windows Update, Windows Update will put the
server in install mode for you.

Whether you want to install these programs and updates while users
are logged in is up to you. I would not recommend it though, just
for sanity sake.

Hi Frank,

The reason typically applications have to be installed when user's are off
the machine is because during install, a terminal service (a server with
terminal services in application mode) will track any changes written to
HKCU and copy them to another location -
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal
Server\Install\Software

What happens then is when other users log on, those settings are propergated
into their HKCU thus making the application work... There is also the same
mechanism with files too but you get the point...

If you install an application when user's are on the machine there is the
potential that data will go into the HKLM section which is not really part
of the app. So hopefully that answers Q1 as to why you need to install
without users on the machine.

Now, Q2 is also related to the above however with updates there is typically
no user data (DLL's are replaced and stuff) so you're normally safe to
update without affecting the machine.

Hope this helps...

Cheers,
Jon

Re: Installation of applications while user are logged on.

I would disagree because the server is still put into install mode. Even
though there may not be any per user settings (and your simply taking a
chance that there isn't you have no true way of knowing what is being done
in a patch or not without thorough up front work) the server is still in
install mode. So the answer is resounding NO do not install ANYTHING when
users are on the system.
