CentOS“-bash: a2enmod: command not found”

It seems that Apache resolves the path to it's long version before passing it to PHP encoded in UTF-8. PHP file functions use the ANSI API of Windows and is unable to deal with Unicode in filenames.

I remember facing a similar problem with Apache/PHP. One solution would be to create some sort of NTFS symbolic link to your folder using a name that solely avoids Unicode characters.

eg.: E:\sites => E:\gonzález\sites

NTFS symbolic link on Wikipedia: http://en.wikipedia.org/wiki/NTFS_symbolic_link

You can get the mklink.exe utility from Microsoft to create such links from the command-line: http://technet.microsoft.com/en-us/library/cc753194(WS.10).aspx

You could try the following command:

mklink /D E:\sites E:\gonzález\sites

Link Shell Extension is a free software that integrates with Windows shell to manage symbolic links on NTFS volumes (you'll find the link in the Wikipedia article above, or you can lookup for "Link Shell Extension" on any good search engine).

Did you check if .htaccess is actually working for that directory? You might need to set AllowOverride to All instead of None (default) on that directory in your apache configuration.
