It's unlikely that the ISA MSDE could get infeted unless it's been
reconfigured to listen on one or more interfaces.
By default, ISA MSDE is not bound to any interface; it's strictly
memory-mapped networking on the box.

This ISA 2004 (MSDE doing the logging)?  If so I'm guessing your ISA is
infected.  But at least it ain't getting' your internal network :)  If
you can, reboot your ISA and see if the problem goes away for a period
of time.  Then patch your box.  Slammer is only memory resident and
doesn't write files so an infection will go away with a reboot (until it
gets infected again).

Hi there

I am seeing something strange, and would appreciate some comment on this
please...

I have noticed an ever-increasing amount of UDP:1433 traffic in my
Packet Filter Log, the bugger is that my ISA's external IP Address is
shown as the source address. My semi-conclusion at this stage is that I
may have a SQL Slammer infected server/workstation in my midst, but I
would appreciate any and all analysis of the following excerpt (BTW, the
destination IP Address range varies quite immensely)

10/4/2004, 15:12:08, <ISA Ext NIC>, 5.0.255.19, Udp, 1434, 137, -,
BLOCKED, <ISA Ext NIC>, -, - 10/4/2004, 15:12:16, <ISA Ext NIC>,
0.0.255.19, Udp, 1433, 137, -, BLOCKED, <ISA Ext NIC>, -, - 10/4/2004,
