Thank you for your response,
How could using 2 servers in two different subnet supporting 15 clients each
in 100 mbps network do for the requirement do. The server could be HT
enabled PIV with 1.5-2 GB of RAM with workstations of PIII with intel 8x0
boards and 64 MB Ram. Could this be a viable option or not.
By flash i meant flash content prepared in Macromedia Flash/Director for
community to be taught about HIV/AIDS and other health issues after the
school is over for general information spread
