Good day.
I need to know how to list shared folders on a computer that I am connected over LAN to, given its IP or machine name.

Thanks ahead.

One single DLL executing what you want. ParamStr(1) should contain the name of the server. Use
GetNetShares <Server>
to execute, replacing <Server> with the server name.
