I am getting quite a few unusual alerts, and am confused with what I am seeing.



The payload of the packet is:

The strange thing is that the source is:

x.x.x.x:1433 (our network)

This looks like your MS sql server responding to someone's unsuccessful login attempt. There was a problem with MS sql a while back where the sql server set up the admin account (sa) with NO password. A worm was written to exploit it and this could be it.
