Deploy VS.NET web app/Need Help

I'm doing something wrong. Can someone help?
- I've got a web application developed on a local IIS installation
(http://(localweb)/myapp.aspx) using VB.Net.
- My remote server that hosts my web site has frontpage extensions installed.
- When I use "Copy Project" in Visual Studio .NET using frontpage to copy to
a subfolder (http://myweb.com/ThisFolder) I get an error message:
"myweb.com:80 requires authoring permission" and it asks for a password and
user name. The user name it suggests is prefaced by the server domain name of
my local installation (myLocalDomain\userid) so this error message must be
coming from my side as opposed to the web site host.
- Copy project DOES allow me to copy the application to the root directory
of my web site (where I don't want it).
- This procedure USED to work flawlessly.
- Have tried to copy just the non _vti type files to the remote server but I
get a server error when I run even a simple aspx page.
What am I doing wrong???
