front page problems

[websterm]

Hi, I've recently migrated an intranet server content from NT to 2000 (both running IIS), the old server had front page 98, the new one has front page 2000. I get a number of FP related errors such as:

FrontPage Run-Time Component Page

You have submitted a form or followed a link to a page that requires a web server and the FrontPage Server Extensions to function properly.

This form or other FrontPage component will work correctly if you publish this web to a web server that has the FrontPage Server Extensions installed.

Click the <Back> arrow to return to the previous page.

AND

Microsoft FrontPage Server Extensions:

http://wwwsite - Error #7000b Message: A FrontPage Save Results component tried to write to "file.name", but access to this file or URL is disallowed because it is located in an invalid subfolder, is not part of the web, or was disallowed by an administrator.

The permissions all look ok, the bulk of the content works fine, including the vast majority of my forms.

Any help would be fantastic.

sorry meant to say - I've checked & reapplied the server extensions.
