How can I tell what notes client version my users are on?

I need to get a list or report of what version my users are on. I cannot seem to find it listed anywhere in the domino administrator. Any suggestions?

Subject: person doc, create a view

in the person doc on the administration tab at the bottom you will see the client release tracking there. problem is, it’s not always accurate. If you enable Log_Sessions=1 on your servers then the log will capture the client release when the user opens a session. Let the logs capture the data for a week then you can use some freeware to parse out the sessions in the log files. Do a search for clientlv.exe or you can find it on www.openntf.org
