Some closure on this:
I found the culprit.
File Name: nettray.exe
File Path: C:\Documents and Settings\%infected-username%\Application Data\
File Size: 30 KB (30,720)
File Attributes: Read-only, Hidden
------------------
Conclusion: After further review it looks like it broadcasts 3 NBNS to
CN.KIND.CD every 5 seconds give or take. I found several hits on
google for Trojan/Backdoor relation to the file.
Thanks to everyone who responded.
Tim.
