I'm not sure if this has already been stated but I didn't see it in the 20 some-odd pages I read nor in a search of this thread so... To get the product working with IIS, simply download the "lite" version of ISAPI_Rewrite and then use the following rewrite command:

RewriteCond Host: hostname.domain.name
RewriteRule ^/(sitemap.*\.(xml|txt)(\.gz)?)$ /forums/vbseo_sitemap/vbseo_getsitemap.php\?sitemap=$1 [L]
RewriteRule ^/forums/(sitemap.*\.(xml|txt)(\.gz)?)$ /forums/vbseo_sitemap/vbseo_getsitemap.php\?sitemap=$1 [L]

Note the leading '/' after the start of the regular expression (^); the rewrite rule wasn't working for me without it. I added two rewrite rules; one for root of my website and one for the root of my forums. I wasn't entirely sure which was appropriate so I figured I'd put both in just in case. In essence, the sitemap will now be found whether it is accessed at the webroot or my forum root...

Looking at the output of the actual sitemap_index.xml file I think the /forums rewrite is definitely required. I'm not sure if there is a reason to have the webroot rewrite in there or not; I'm guessing not... If someone in the know would like to chime in with a response that would be great.

In the meantime, everyone should know that there is a free utility (ISAPI_Rewrite the "lite" version) which enabled you to configure this plug-in completely using IIS and Windows.
