Is there any thing unique to identify the client machine(desktop) other then IP address? I have a situtation where in my intranet, i need to identify the machine uniquely and do some processing, But the problem is that we dont haev static IP address, but dynamic IP address. I want to display a particular screen if the user is using a perticular computer or network node
Well... there is no simply solution to this problem... to make matter worst, you have dynamic IP address... sigh...
Couple of options:
- Plain, old DNS. Each machine could have a name as well as an address. Discriminate on the name.
- If you cannot change your DNS system, use Zeroconf's DNS Service Discovery. In that scenario, each machine advertises it's name and IP address without the need for a centralize DNS server. Out-of-the-box, this only works in a subnet through.

- Use a X509 client certificate.
- An oldy, but a goody... use ident (aka Identification Protocol):

None of those solution are perfect, but at the very least you should be able to automatically identify a machine on an intranet one way or another if you really want to :)
