It seems to be relatively easy
to install games on an XP Pro box under
the administrator account, and I seem to be having pretty good success
at getting them to run. However, they will often not work under other
accounts on the same machine. Part of the trick at getting them to run
seems to be to give the other accounts "Power User" group rights.
However my old NT 4.0 Domain server does not have the "Power users"
group, so it looked for a while like I would have to create local
machine accounts with membership in this group. A bit of web searching
turned up this
page that suggested there was a way to make the NT4 domain user
group appear to be called the power user group and this would have the
same permissions. The trick was to go to the workstation where the
power user group is needed (actually it sounds like this will apply to
all machines) and execute this command:
net localgroup "power users" /add "DOMAIN\Domain Users"
once I did this it became possible to install software as a regular
user and a lot of the programs that refused to run under other accounts
will now work.
