Monitoring available server memory via ASP?

Hi,
Is there a way that the available memory on a server (WinNT 4.0) can be monitored via ASP?

I have an ASP page that is currently used by 72 people. It collects data supplied by the user and then connects to the company's computer. It runs some sessions on the company computer supplying the data to the sessions. During this time (about 15 seconds) a relatively large amount of server memory is utilized.
The company wants to bring 116 more users on-line. The data center has a concern that if 188 users try to submit data at the same time the server will not have enough memory and will crash. The server would handle about 175 simultaneous submissions.

I'm thinking that if I could monitor the available memory I could put a delay in the submission routine until enough memory is available.

Thanks,
Al.
