After install OCS Inventory Agent Version 2.9.0.0 or  2.9.1.0 and waiting 2 days  IpDiscovery GUI is empty.

Next on windows Agent execute OCSInventory.exe /ipdisc="10.2.222.0" /debug=2

in agents logs 

AGENT => IpDiscover required by /IPDISC on network 10.2.222.0

IPDISCOVER => Scanning to detect IPv4 enabled hosts for network <10.2.222.0> with <100> ms between
