We have the Inventory Only client deployed. All is working well except that the "Login name" field is only filled in with about 10% of the scanned stations and those 10% change after every scan. It seems that this field is filled in and emptied randomly. ZCM Version is 10.2.1 (did not work in earlier version either). Workstations are W2K and XP, all with client 4.91sp2. Happens with both OS's. The scans on the workstations happen when users are logged in during the day. I have changed 'determining Primary User' but that does not seem to affect anything. Any idea where this field gets its value on the local workstation ?

thank you
