Anyone else had stuff like this? Sometimes I get an alert that some windows utility or program is trying to send something through TCP/IP, and it just doesn't make any sense for the program to do so. For instance...

Outgoing ICMP type 8 (ping) from xxx.xxx.xxx.90 to xxx.xxx.xxx.91 (my computer is xxx.xxx.xxx.90)... but guess what program! Disk Defragmenter! (c:\windows\defrag.exe). Now why would microsoft make a disk defragmentation program that pings the next address after your own?

Anyone else have examples to post? I had a few other weird ones, but I don't think I kept the particulars.
