How to Change the Log File Directory in IIS7
Exchange Server
Post author:Written By Paul CunninghamPost published:August 3, 201113 Comments
On an Exchange Server 2010 Client Access server a lot of logging can be generated by IIS for client traffic such as OWA and ActiveSync.
For some servers the need to retain this logging for a long time may cause a disk space issue. To resolve this you can simply change the log file directory that IIS7 uses.
Open IIS Manager from Administrative Tools and click on the Default Web Site.
Double-click the Logging icon.
Type in the path to the new log directory that you want to use, or click Browse and navigate to it.
When you’ve entered or chosen the new log directory click Apply.
The new directory will be created (if it doesn’t already exist) when the next log entries are written by the server.
You can copy the existing logs from the old location to the new log directory. Just be aware that the server may have already created a log file in the new directory for the current day, but you can simply tell the copy to keep both files by renaming one of them. Or if you make the change during a period of the day that there is no activity then you probably won’t run into any duplicate file name issues.
We can also make the same configuration change using Powershell. From a Powershell window type the following commands.
PS C:\> Import-Module WebAdministrationPS C:\> Set-ItemProperty 'IIS:SitesDefault Web Site' -name logfile.directory "D:IISLogs"

Actually, you only have to restart the website in order for the new log file location to take affect. Add a line to your script to bounce the site and voila!!! I recommend creating a folder structure as follows: d:\IIS LOG FILES\WEBSITE NAME. A folder will get created inside of the WEBSITE NAME folder but at least you know which site you are looking at.

For me in IIS 8.5 the httperr logs location persisted to the old location after I made a location change in IIS at the server level. The sites were logging to the new location, but not the httperr log. WinServer 2012 R2.
I restarted IIS at least twice. I verified the sites retained the new logs location and the server level as well.
I checked hklm:SystemCurrentControlSetserviceshttpparameters
ErrorLoggingDir was still set to the old location. I rebooted the server. Same results.I looked everywhere to try and find a setting to update this registry value and did not find anything.
I saved a backup of my registry and then updated the setting manually.
I reset IIS. Still did not update.
I rebooted the server. Finally. The httperr log was created and logging to my new location.zohaib 20 Jun 2016Reply

IIS restart was required. Did it twice to verify IIS restart is required. Each time I changed the log location and tested I got 500 error until I restarted IIS.

Same question here!!!
Does IIS have to be restarted for this to take effect? I do not see a change using the powershell commands.Paul Cunningham The Real Person!

“The new directory will be created (if it doesn’t already exist) when the next log entries are written by the server.”
I’ve just retested to confirm that. At least on my own server it is working that way.

No, it doesn’t require a IIS reset.
