Setup:

InfoPath 2007 browser form
Moss 2007 (one web/query server, one application/index server(hosting
Central Administration), one DB server)

When I create the form that uses a web service (http://server1/
vti_bin/UserProfileService.asmx?WSDL) to get GetUserProfilebyName method to
retrieve user info and publish it to my dev server (which is both web/query
& index server) it works fine!!

Problem is when I try to publish it to my production server (see above
"Setup"), I get

An error occurred accessing a data source. "Error 6932"

In SharePoint logs I see below:

"The form could not retrieve data from
http://server1/_vti_bin/UserProfileService.asmx because it would violate
cross-domain restrictions. To allow this connection for
administrator-approved form templates, enable full trust for the form
template, or add the connection to a Data Connection Library.  For user form
templates, cross-domain connections must be enabled in SharePoint Central
Administration, and all connections must be in a Data Connection
Library....."

Should I install InfoPath on my web server and than try to publish it? or
according to below link, put data connection on MOSS

Any help is needed.
