Determine Ram installed - on remote PC

I'm looking for a tool that will run from a DOS/Command Line prompt that will return the amount of RAM installed on a remote PC, how much is in use, how much is available, etc.

Normally I would use: systeminfo /s: to get not only the installed ram but system uptime as well. Wowever, the method I'm using to call systeminfo times out before the data gets returned.

I've discovered an older MS tool called uptime.exe that gives me that piece of info, but now I need the installed Ram totals.

Heck, it'd be nice to be able to get the OS Name & Version, as well as CPU info.

Again, these would have to be DOS apps, those are the easiest ones to pipe info out of! =)

Any suggestions would be greatly appreciated.
