Exchange 2003 and NT Backup - log files not being flushed

I have NTbackup running on Exchange 2003 and for the past little while even though we have circular logging disabled the logs keep building. I have seen some notes about checking to see if a log file is corrupt and fixing via ESEutil etc. but I am wondering if as a quick test and possible cleanup if I enable circular logging to create a new set of logs and then disable it might that do the trick of ridding us of this problem?

I believe disabling re-enabling circular logging requires a services restart - did you do that after the change?

if your backup is completing without errors then your logs should be flushed, monitor your event log at the end of the backup any errors ?

lineonecorp == do not enable circular logging. period.

you can use ntbackup to flush logs.
All you need to do is configure a normal backup and flush logs. see the guide below.

I don't want to have circular logging enabled for good just as means of perhaps fixing this problem - e.g. let it run to see if it works and then turning it off. I have additional backup of the Exchange server so it's not a matter that if mess up the NT Backup I will have no recourse. I am just wondering what the implications are of switching back and forth.

when you turn circular logging on -- your logs will be flushed useless
when you stop circular logging - log genereation will restart
