i know that acording to some microsoft papers, i can prevent sync 
attacks

Sync attacks, or SYN attacks?

in every compurter by modifying the registry (at least in win nt 
4.0 & 5.0). In a large network this only means one thing: tons of work 
without forgetting this may carry another tons of problems if we are not 
cautious enough...

I'm not sure where you got that idea.  The Registry change (for SYN attacks, anyway...don't know what you're referring 
to regarding SYNC attacks) can be scripted using batch files or Perl very easily.  When rolling out the change, of 
course, you'd want to run it on designated test systems first, in order to identify any issues that should occur.  
That's your "caution".

but i was wondering if there is such a way to prevent sync attacks from 
an upper level, like for example cisco switches or routers, may be a 
firewall?

Actually, yes...in most cases.  RTFM.
