Periodically, I also get similar alerts. These alerts originate from other
computers in my house . . . one originates from a wired computer and the other
from a wireless laptop.
This is rather interesting, considering that both computers from which the
alerts originate are on the same workgroup; however, the wired computer on
which the alert appears is on a different workgroup. Both workgroups use the
same router, however. Also, I notice that the alert from the wired computer
always always attempt to connect via UDP Port 138; while the wireless computer
attempts via UDP Port 137. I don't understand the significance of UDP.
The alerts are generated and denied by CA Security Suite, which automatically
denies connection, without any known consequences. I do wonder what would
happen if I did not have the Security Suite. IOW, would the WinXP firewall
have blocked the connection?
Thanks.
