asp htaccess 301 redirect - .htaccess

Question

I'm trying to redirect 3 pages but for some reason, it doens't seem to work. Site is built with asp
<IfModule mod_rewrite.c>
# Make sure directory listing is disabled
Options +FollowSymLinks -Indexes
RewriteEngine on
# Re-write for PDFs requests not pre-pended with /pdf/ I.E. in the root - prepend /pdf/ - Use negative look-ahead - If the file doesn't exist you get a 500 though sadly.
RewriteCond %{REQUEST_URI} ^/(?!pdf/)(.*)\.(pdf)$
RewriteCond %{DOCUMENT_ROOT}/pdf/$1 -f
RewriteRule ^(.*)$ /pdf/$1 [L]
# If the URI is not in /images,/pdf,/css, or /js let the handler process it
RewriteCond %{REQUEST_URI} !^(/images/|/pdf/|/css/|/js/)
RewriteCond %{REQUEST_FILENAME} !handler.php
RewriteRule ^(.*)$ handler.php/$1 [L]
# If the URI IS in the above directories but the file doesn't exist run it through the handler as well
RewriteCond %{REQUEST_URI} ^(/images/|/pdf/|/css/|/js/)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ handler.php/$1 [L]
# Permanent URL redirect
Redirect 301 /Server_Rack_Cabinet_RS_42U.asp http://www.rackmountsolutions.net/cruxial-core-1000-series-server-rack.asp
Redirect 301 /Sound_Dampening_Proof_Server_Rack.asp http://www.rackmountsolutions.net/AcoustiQuiet_Soundproof_Server_Rack.asp
Redirect 301 /Relay_Rack_4_post.asp http://www.rackmountsolutions.net/4_Post_Server_Rack.asp
</IfModule>
The # Permanent URL redirect portion doesn't seem to work. The above is the entire code I have in the .htaccess file.

Since this site is running on an IIS server, there was a web.config file overruling the .htaccess file somehow. See the to see how i did it. The web.config file was in my site's root folder.
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Env-leader-redirect1" patternSyntax="ECMAScript" stopProcessing="true">
<match url="^Server_Rack_Cabinet_RS_42U.asp" />
<conditions>
<add input="{HTTP_HOST}" pattern="^www\.rackmountsolutions\.net$" />
</conditions>
<action type="Redirect" url="http://www.rackmountsolutions.net/cruxial-core-1000-series-server-rack.asp" />
</rule>
<rule name="Env-leader-redirect2" patternSyntax="ECMAScript" stopProcessing="true">
<match url="^Server_Rack_Cabinet_RS_42U.asp" />
<conditions>
<add input="{HTTP_HOST}" pattern="^www\.rackmountsolutions\.net$" />
</conditions>
<action type="Redirect" url="http://www.rackmountsolutions.net/cruxial-core-1000-series-server-rack.asp" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
