asp.net invalid file name for monitoring

[Ron Simpson]

I am trying to run asp.net pages. The server is accessed
via http://sitename/username

I have verified it is using port 80 and aspx extensions
are configured. But when I run and asp.net page I get the
following error:

Invalid file name for monitoring: 'E:\'. File names for
monitoring must have absolute paths, and no wildcards.
Description: An unhandled exception occurred during the
execution of the current web request. Please review the
