RewriteCond parse error (Isapi Rewrite ver 2)

[npd1164 Profile]

This line (adopted from apache mod rewrite) is throwing a parse error for me:
Unrecognized string: RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f

Can't quite figure out how to rewrite it for Isapi rewrite ver 2.

The cond/rule set set I'm trying to use is:

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule ^(.*)$ /404.php? [L]

Hello,

The thing is that ISAPI_Rewrite 2 does not support the syntax you provided.
This syntax is applicable in ISAPI_Rewrite 3.
There is no direct alternative for it in v2, you should only exclude all physical files and folders by listing them like this:

RewriteRule /(?!(?:index\.php|css|images|js|etc)).* /404.php [I,L]
