Dear all,
I publish Infopath forms as template to SharePoint. But customer require to check permissions for InforPath form. I created a special SharePoint group. Than I created specific filter in InfoPath using service:
http://my_site_name/_vti_bin/UserGroup.asmx?WSDL
On one of my environments everything is OK. But on another I caught an exception during configuring data connection on the step where I type URL and press ok:
InfoPath cannot find or cannot access the specified Web service description.
The file is not a valid XML file.
Not enough storage is available to process this command.

Please, help me to resolve this issue as it is environment for presentation a new functionality for customers.
Best regards,
