I have a suspicious IP transmission from my computer each time I start up.
I use Wallwatcher to monitor traffic on my Linksys DSL router and can see
this activity and ID the location. but what application on my computer is
making the request?.

How can I trace the source application that made the request for a
particular IP output?

I my case its something from WilTel Communications group 6
9-44-123-110.wcg.net.

Any thoughts appreciated.
thanks

Assuming you are using windows, during the connection, you can check with
netstat -o

Depends on which Windows.
In Win98SE's netstat "o" is not a valid option. It is in WinXP.
For other flavors of Windows I have no idea....

For Windows operating systems, TCPView (free) from
<http://www.sysinternals.com/ntw2k/source/tcpview.shtml> gives you a gui,
constantly refreshing display equivalent to netstat. For Windows NT/2K/XP, it
will also provide you the PID of the process owning each port.

For more information about any process in question, Process Explorer (free) from
<http://www.sysinternals.com/ntw2k/freeware/procexp.shtml> provides way more
information than Task Manager.

Both programs are small and self contained, and require no complicated install.

Cheers,
Chuck
