Permalink Problems – Multi Page Posts

Hello,

I have recently moved from a Linux host to hosting my WordPress site within a Windows server environment.

I am having some exceptionally weird issues with Pretty Permalinks, specifically when a post has multiple pages. If a page has one or more pages, the link from the post does not work it says there is a redirect issue at play.

However if you add a trailing slash manually the page loads fine. For example:

http://www.daveplays.co.uk/reviews/sapphire-r7-260x-review/436

http://www.daveplays.co.uk/reviews/sapphire-r7-260x-review/436/2

http://www.daveplays.co.uk/reviews/sapphire-r7-260x-review/436/2/

I noticed in my permalink structure that it was set to /%category%/%postname%/%post_id%

However if I set it to
/%category%/%postname%/%post_id%/ which adds the trailing slash the page will still not load, until you remove the trailing slash

My web.config file which IIS picks up fine looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<system.webServer>
		<staticContent>
			<remove fileExtension=".svg" />
			<mimeMap fileExtension=".svg" mimeType="image/svg+xml" />
		</staticContent>
        <rewrite>
<rules>
<rule name="WordPress Rule" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php?page_id={R:0}" />
</rule>
</rules>
</rewrite>
	</system.webServer>
</configuration>

If I use IIS to force a trailing slash I run into the same issue. If I use any other permalink structure than the default ugly one the page links do not work.

Has anyone experienced this issue?
