Hi all Experts,

I was facing same problem then i tried according to checkpoint suggestion on
http://www.checkpoint.com/defense/ad...i-2003-11.html
Also i changed in dcerpc.def file as follows
#define ALLOW_135 0 to 1
But still it was not working,
Then when i disabled dynamic port protection mode it was working.
My Point is By disabling this what kind of attack can i expect & how should i prevent this ?
For protection temp. I blocked all 135 to 139 & 445 port on router.
Is it correct ?

Thanks,
Regards,
Jeetu
