Problem with 302 redirects

My website address www.baysidejewelry.com is being 302 redirected to www.baysidejewelry.com/default.aspx. Is there some code in NopCommere that does this? I checked my .htaccess file at my root and there are no 302 redirects. Because I have a temp redirect to the home page of my site the search engines are ignoring our site. I have to resolve this ASAP.

Seems that you have IIS 6.0. It always works this way by default (adds 'Default.aspx')

Wow thanks for the speedy response. Yes, we do have iis 6.0. So do the redirects from iis overwrite the ones from .htaccess?
