Dot Net Nuke generating long URL showing up as crawl errors!

[EricSchmidt]

Since early July a DotNetNuke site is generating long urls that are showing in campaigns as crawl errors: long url, duplicate content, duplicate page title.

URL: http://www.wakefieldpetvet.com/Home/tabid/223/ctl/SendPassword/Default.aspx?returnurl=%2F

Is this a problem with DNN or a nuance to be ignored?  Can it be controlled?

Google webmaster tools shows no crawl errors like this.

Are all of the problematic URLs variations of the SendPassword page? Otherwise, if you are getting long URLs for other pages, just make sure you are using rel=canonical tags to tell the search engines the correct URL to use for each page.

If at all possible use IIS URL Rewriter so that you can canonicalize your site structure.

If you have a smaller site, and it's in the early stages I'd try using other CMSs and software to see if you can find something that you like. I love Wordpress, and I use it for everything.
