Computer dropping IP from DHCP

Hello All 

im experiencing a problem with some computers dropping IP the address

with a release / renew the computer is getting a new ip from the dhcp server and after 5 minutes just goes down and doenst repond any more 

 

in the arp table is shown as incomplete

 

if I exclude that ip in the dhcp server and force the computer to get a new ip , it get a new ip and the happen the same again , reply for 5 min and goes down again 

 

I dont have duplicated ranges or something using the same range

 

what could be causing this? is possible something scanning this range? we have several locations, some other locations using the same range? 

 

the thing is not all of the computers in this range has the problem 

 

thanks

Hi,

Can you try using the same scope on a different server or use a switch or router as the DHCP server and see if it happens again?
