Apparently MediaWiki is trying to create a folder on your server, but it is unable to do it, probably because it doesn't have permissions to do so.

It may be because of the location of $wgCacheDirectory or $wgDebugLogFile. Check if both are set to an existing folder and that the IIS server process (or maybe PHP) is able to write on them (you can try givin full permissions to the special security group EVERYONE).

You can comment out $wgDebugLogFile if there's no other error, since it's only for debugging purposes.
