As the title, I've just installed IPAM3.1, everything seems ok but the process of subnet scanning doesn't work.
The status is always "Next scan : ASAP" & there is an event log : "IPAM Service [WIN-B8NLDV1SDNG] is unable to communicate with Job Engine. Network Scanning is offline.", even I replaced .sdf file and untick read-only box.
I installed IPAM 3.1 on Windows Server 2008 R2 Ent.
