I think google can't access my pages.

Always leave a blank line between user agents.

User-agent: *
Disallow: /productimages/
Disallow: /admin/

User-agent: googlebot
Disallow: *.asp

If the pages are no longer required, the safe and sensible thing to do is delete them - the web has quite enough clutter; also, particularly if any links exist to the unwanted pages, they may still appear in the serps as URLs or supplementary results.

Thanks for the reply!

I can't delete them just yet. I need to do research and find out more information about them.

Can spiders index the new pages that have the .aspx?

Also, Why is that space needed?

Thanks!

Also note that this robots.txt will allow googlebot to index /productimages/ and /admin/ because they're not in the Googlebot specific section.

Anyone else?

Can spiders index the new pages that have the .aspx?

Thanks...

Yes, if you don't want them to, use:

Disallow: *.asp*
