File execution on shared drives

Hi,

I am doing a test on two servers at work.

Netbios on the two servers is enabled and accessible to those who enter correct username and password combinations.
My question is this:
If someone has access to a computer through Netbios (net use * \\192.168.0.1\C$ /U:sarid) can they execute programs that would execute on the server itself and not on the client that issued the command? If so how?

Thanks for your time.
Regards,
sarid
