Hello,

Windows 2012 R2 (with all latest updates) configured to keep IIS logs on a remote CIFS share (\\nas\IIS). No issues with the logging, the file is rotated and everything is great.

Today I tried to add additional logging field (X-FORWARDED-FOR) and once click on Apply the logging stopped working. There is no file with _x created. Removing X-FORWARDED-FOR restores logging.

Changing the logging location to be on a local drive and enabling X-FORWARDED-FOR worked fine.

Anyone with the similar issue?

    Hello there,

    Starting with IIS 6.0, you can write log data to a remote share over a network using a full, Universal Naming Convention (UNC) path. For example, you can specify \<servername><LogFileFolder> as the storage directory for your log files, where servername represents the name of the remote server, and LogFiles represents the name of the directory where the log files are stored.

    Remote logging enables you to set up centralized log file storage and backup; however, it is slower than standard methods of logging. Although HTTP.sys, the kernel-mode driver in IIS 6.0, buffers 64 KB of log data before writing to the log file, https://learn.microsoft.com/en-us/previous-versions/iis/6.0-sdk/ms525284(v=vs.90)

    Hope this resolves your Query !!
