>From the log you posted, it looks like it's trying to attack your web 
server with a buffer overflow.  Probably this is a compromised Windows 
machine, and the owner isn't aware it's doing this, but either way, you 
should contact your ISP.  Telia doesn't seem to be very different from 
most larger ISPs, and they may not react quickly or at all.  You could 
also try using smbclient (part of the Samba port) to send a Windows 
popup message to that machine.
