Sharepoint, deploying aspx pages

That is another memory help for me.

When i want to add asp.net pages to be used from a Sharepoint Site i must copy them to the ...\60\Template\Layouts\MyFolder Folder.
That must be done when i developed an asp.net aspx page and want to deploy them to the Sharepoint server.

And the way to call them 'd be http://server/site/_layouts/MyFolder/mypage.aspx

Unable to display this Web Part

Today i tried to navigate a Sharepoint site where normally i used to navigate without problems, but i got the next error message.

Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Windows SharePoint Services-compatible HTML editor such as FrontPage. If the problem persists, contact your Web server administrator.


Trying and trying this was solved when i restarted IIS.
