I had this problem once before in our development environment, and now seeks
into our development of our production sharepoint site, it is happenning
again.  Our Web Application is preventing InfoPath from publishing forms that
are Browser-Enabled.  It reports "This form is browser-compatible, but is
cannot be browser-enabled on the selected site."  Further it reports "This
may be caused by one of the following reasons: The server is not running
InfoPath Forms Services.  The necssary features are not available on the site
collection.  The policy setting on the server does not allow users to
browser-enabled form templates.

Some facts:
We are running MOSS 2007 Enterprise Edition.
Separate SQL Server (SQL 2005 Cluster).
Single Web server for all other services.
I am a site collection administrator.
I can browser-enable and publish to other site collections on other
web-applications.
I am trying to publish to either a previously created or new form library.

Any help would be greatly appreciated.
