I have an interesting problem. My client has 2,500 workstations. They all
have the latest client (4.91 SP4) and they want to install Password
Self-Help. Easy! Yes BUT....

There are almost 1,000 workstations that don't have NMAS or Challenge
Response installed.

Does anyone know of a way in which I can set this up either in the Login
Scipt or some other way, to get a silent install of both NMAS and
Challenge Response without having to visit over 1,000 workstations.

I tried reinstalling, but as you know, you can't reinstall withut first
removing the client. I also noticed that even if you install a newer
version using the ACU and tell it to install NMAS and CA, if it isn't
already installed it just ignores you and refuses to install it!
