I have a site that was initially set up under one domain, then changed to another. The first address still works (IIS host headers) but I have my site set with the "Preferred Host Name" setting to push everything to the new one.

When I submitted my sitemap to Google, it warned me about several "not allowed" URLs, and if I visit sitemap.ashx in the browser I can find several page addresses that use the original domain.

This looks like a bug, but I thought I'd ask here first!  Why is this and how do I fix it?

The site map is here http://www.esdmdata.co.uk/SiteMap.ashx

and the bad pages are the ones using www.esdm.no-ip.co.uk

That's what I would have thought, but I've checked the pages and they all have a relative path, e.g. for "<loc>http://www.esdm.no-ip.co.uk/gis-courses</loc>" I find this in page settings "~/gis-courses".

However, I have also noticed that this page appears in the sitemap.ashx twice, once with the "good" domain and once with the old one, the former having a recent lastmod date, the latter with a lastmod date from August 2011. I'm puzzled how this would be possible!

I cannot find any trace of this particular "gis-courses" page being duplicated in PageTree.aspx.

Time to look in the database...

Thanks Joe - I found them in the database - the pages had been given different friendly names meaning I couldn't see them in PageTree.aspx
