Hello,
I have a set of InfoPath 2010 forms exposed via InfoPath forms services hosted in Sharepoint 2010 SP2. The InfoPath forms do not contain any custom code, but do contain rules and data connections to web services hosted on a different machine within the clients network. The InfoPath web forms are accessed over Http/s and most of the time work great. However occasionally my users receive a Critical error and have to close the form. Additionally the following error message (I've removed the name of the server) is logged in the event viewer of the sharepoint box:
Source: InfoPath Forms Services
Warning
Date: 6/9/2014/3:44:37
Exception occurred during request processing. (User: , Form Name: SAP Vendor Master, IP: , Request: https://servername/sites/SAPMDM/SAPMDM/_layouts/FormServer.aspx?XsnLocation=https://servern/sites/SAPMDM/SAPMDM/SAP Vendor Master/Forms/template.xsn&SaveLocation=https://servername/sites/SAPMDM/SAPMDM/SAP Vendor Master&ClientInstalled=true&Source=https://servername/sites/SAPMDM/SAPMDM/SAP%2520Vendor%2520Master/Forms/AllItems.aspx&DefaultItemOpen=1, Form ID: urn:schemas-microsoft-com:office:infopath:SAP-Vendor-Master:-dataFormSolution, Type: InfoPathLocalizedException, Exception Message: The security validation for this form is invalid.)
I'm wondering if I need to modify the FormServer.aspx per this link:

I appreciate any advice.
Thanks,
