My IIS7x server is logging all fields to W3C format. I'm using LogParser and sending each row out to SQL for further analysis. After a few months worth of logging, each row finds a null value in sUserTime.
Under what conditions would some component within IIS or Windows write a value into sUserTime? I'd like to be sure it's always null so I can merge the currently separate 'Date' & 'Time' fields into it using an update statement that depends on 'is null' condition.
thx
