No, there's no problem, since the script waits 5 seconds in order to 
give the client time to update its record. And if the client doesn't do 
it, the the script will do it.
In fact you can ignore the section about the GPO.
I had to modify something in the dhcp configuration though, I cannot 
tell what now since the server is in a VLAN that's not accessible 
outside the office, and I'm not there right now.

I case you need it, this is what I have in my dhcpd.conf


   on commit {
     set noname = concat("dhcp-", binary-to-ascii(10, 8,
"-",
leased-address));
     set ClientIP = binary-to-ascii(10, 8, ".", leased-address);
     set ClientName = pick-first-value(option host-name, host-decl-name, 
config-option host-name, noname);
     execute("/etc/dhcp/update.sh", "add", ClientIP,
ClientName);
   }

   on release {
     #ClientIP and ClientName are stored in the lease
     execute("/etc/dhcp/update.sh", "delete", ClientIP,
ClientName);
   }

     on expiry {
     #ClientIP and ClientName are stored in the lease
     execute("/etc/dhcp/update.sh", "delete", ClientIP,
ClientName);
   }


this is the version of my dhcp server:

ii  isc-dhcp-server       4.2.4-7ubuntu12 amd64           ISC DHCP 
server for automatic IP address assignm
