There are several options on making search engine friendly redirects on a Windows Server. If you don't have any admin access, you can still use VB script in ASP pages for redirecting:
Code:
< %@ Language=VBScript %>
< %
Response.Status="301 Moved Permanently"
Response.AddHeader "Location", http://www.example.com
%>
If you allow asp instructions to be used in .htm pages, you will have a SEO 301 redirect.
Another option is to use .htaccess file. But your Microsoft Windows Server should be able to run Apache modules.
