Reverse TCP Desynchronization Attack?

I was going through the firewall log files for ESS out of boredom and came across this...

(I added the to and from.)

My question is, what's a Reverse TCP Desynchronization Attack?

 

Hi ! Open Eset Smart Security's help file and you can find out what it is

 

here is some real help.

 

whilst copying somefiles over trusted network (40gb ish to transfer..) about 20minutes in, it stopped and said "network name is no longer availiable"
so i looked in ESS (beta2) log, and saw

26/08/2007 16:59:51 Detected TCP Desynchronization attack 192.168.0.7:139 192.168.0.2:3024 TCP

why?


cheers

p.s was a MCE2005 pc (no firewall/av) gigabit wired to XP PRO SP2 pc (with ess beta2)
