Hi experts,
 
The windows update has been configured through fsecure patch management .  But it is not working for few pcs , and once we change the ip adress of those pc it is working!   
All the enduser pcs are in the same subnet as 192.168.1.0 .  
 
firewall is fortinet and i couldnt see any policy related to this. 
 
So please advise how to resolve this .
