FSSO not updating IP address change

Hi,

Our FSSO Collector (we don't have DCAgent) doesn't update the ip changes. I think that the problem is that he doesn't know all workstation names. Some entries have IP in IP address column and device name in workstation name. Others have ip address in both, address column and Workstation name.

How does the FSSO know the workstation name?

I have seen the AD Event 4624 and the field workstation name is blank. But, there are some entries in the FSSO Collector that have workstation name and in the corresponding AD Event the filed is blank.

Kind Regards,

Iratxe
