Wild Packets' OmniPeek also provides this capability with remote capture engines.

It's a great tool, but $$$$ for the enterprise license.

This depends on what you mean by remote PC.

It is possible to place a tool such as wireshark on a remote pc then use a remote tool such as Windows remote desktop 
to take control of the remote PC and capture traffic.

If the remote PC is actually on a large campus such as a university, and the network is Cisco (other switches might 
also have this capability), and there are no dedicated routers (such as a 2900 or 3800 routers -the Cisco 4500 and 6500 
devices are switches not routers), a remote span port can be setup to mirror traffic across the switch fabric.  This 
would enable you to capture traffic from the remote PC to a capture station.  I have done this, and it's not difficult.

Finally, some companies, I believe Opnet is one, make a capture tool that will send the trace file to a collection 
station across a network.

Good Luck
Bill

Hello,
I'm wondering if there is a way to sniff a remote computer's traffic, 
that computer would be on a different lan, and how could that be 
blocked. as far as i know, wireshark sniffs only my computer and 
ettercap only on the same lan.
