Reclaiming Disk Space Lost to IIS Logs on SBS 2003 and SBS 2008

Today we are going to discuss an SBS "house cleaning" tip.  If you have been running SBS 2003/2008 for awhile you may be using a lot of disk space to store old IIS logs.  This is especially true if your clients are heavy OWA, ActiveSync, RPC over HTTP, or SharePoint users.  A recent customer of mine had files dating back to 2004 and was using almost 2 Gigabytes of hard drive space to store these old logs.

To reclaim this space all you need to do is to delete the old IIS log files.  Please be sure to back them up before deleting, just in case you need the logs in the future.  I usually try to keep a week’s worth of logs and delete everything older than that.  The logs will be in folders underneath C:\Windows\System32\LogFiles\ in SBS 2003 and C:\inetpub\logs\LogFiles in SBS 2008 by default.   Additionally there is a Remote Web Workplace log stored in SBS 2008 in the following location which can grow rather large C:\Program Files\Windows Small Business Server\Logs\WebWorkplace.  If your log files are not stored in the default location, you can run the below command to determine the log file directory configured in IIS.

Note: It is inadvisable to search your hard drive(s) for *.log and delete all that you find.  Many programs actively use information stored in .log files, such as Exchange, and deleting the file may cause issues including potential data loss.

  • This is an excellent tip. Do you have any more hidden gems like this one?

  • I find it funny you're just now getting around to telling people about IIS log build up. I posted a method for doing that on my blog site back in 2006:

    Yeah!  Listen to Kevoh!  He will be the sole arbitter of what can and cannot be posted in all technical blogs on the internets going forward.  Think of the great inconveneince caused to his 7 or 8 regular readers when they had to read about a similar issue twice in the last 2 years.  The humanity.

  • I wrote a tool called IISLogs starting in 2004 (wow 10 years ago) that takes care of this automatically. www.iislogs.com (there is a service or console app version)
