Just to confirm, its just one log file which is very large. When I tried to rename it, I got an error stating it was in use by the system so I guess I need to stop a server before I can rename/delete or move the file?

Hi,

those logs are from exchange and are mainly for troubleshooting or viewing security stuff.
I usually delete them, if I get into problem with space, since they take some 30Gb on my server, in time period of 2 months.

I would change logging direction for IIS, then restart IIS, for changes to take affect, and then you could delete those files (or backup and open that log  to see what is going on).

PS: If you have WSUS then maybe there are information regarding that.

Take a look at this article: http://blog.ronnypot.nl/?p=752

Regards,
Ivan.

Yes, you can delete the log files that are in that directory.  There will be no net effect on your server.

What you can do is reconfigure the logging feature in IIS to rotate the logs out on a regular basis so that you don't wind up with excessively large log files.  You can also reconfig the logging feature to save the log file somewhere else other than the boot partition (c: drive), this helps avoid the situation where the log files clog up the c: drive and causes operational issues with the OS.

If you reconfigure IIS' logging feature you do not need to restart IIS.

I thought so but the exchange server has just stopped accepting incoming messages (outbound still working) Suspect a space issue since C drive has 4.41gb of 171gb - just searching for stuff to delete.

I would check to see if the size what the size of the mail.que file is.  This is short term message storage in Exchange, it can help in quickly restoring message if needed.

If you've used Ex2010, this is the new name for the functionality formally known as Transport Dumpster (I like the old name better, anytime I can say "dumpster" in a technical discussion and be serious about it, I enjoy my job even more)

The size of mial.que is dependent on 2 things, your retention settings and the message volume on your Exchange server(s).

I managed to move a couple of PSTs from the C drive and got back 24gb so thanks for pointing me in the direction of lack of space.
