Archive Plugin 404 Error Permalinks set to Post Name

When I place the Archive Plugin in on the Primary Sidebar

Archive Plugin? Do you mean the default Archive widget?

Yest the default Archive Widget.

Check that mod_rewrite is running on your server.

Where would I find that, I am a newbie?
Function.php?

Sorry I am a newbie, I see I have to check .htaccess, will do.

The site is hosted at Godaddy on a window server. This article says mod_rewrite is not supported.

Do I have to switch to Linux hosting?

Links are working now. I am on a window server, running IIS 7 and PHP 5.4
I created a webconfig file and since my permalinks are set to postname I had to have action type like this… <action type=”Rewrite” url=”index.php” />

Here is full code…

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<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" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
