Hi All
I have an infopath 2007 browser-enabled form that contains a data connection to a web service that returns a list of active directory users. This then populates a drop-down list in the infopath form. I have created the required data connection library and udcx file for the data connection and the udcx file(s) are approved. I can successfully load the form in a browser with the drop-down populated with the AD users in a browser when running it on the server MOSS is hosted on, but receive an data source access error when run on any other machine. The strangest issue here is that IT WAS WORKING for around a month from other machines. I have tested this on other forms as I am changing all of my Infopath 2003 forms to be web-based and the same issue occurs on other forms I am testing, ie works on the server but nowhere else.

The security level for the forms are domain and I have tried using the data source on both forms that are uploaded directly to a form library and to sharepoint central admin with the same result. I believe I have enabled everything required in Infopath services in central admin and struck on what to try next. The issue only occurs when running the forms in a browser on machines other than the server. So if I open a form in the infopath 2007 client on any other machine, the form(s) load successfully.
Any help will be highly appreciated.
