Thanks,
I have done that as well. I have literally tried every method for this and all result in the same error: Network Path was not found.
For now, my only Band-Aid fix is to create library, publish once, test, find changes, delete library, recreate library, publish, test....
There are many methods for form creation within SharePoint. The method I prefer to use is as follows:
1) Create .xsn
2) Name file (FormName_DDMMYY.xsn)
3) Create Forms Library
4) Open Library with explorer > open Forms Folder > Paste in .xsn
5) Edit Library settings > Advanced settings > Change template name to match copy I pasted in
6) Edit Form Template > Save over Top of From Template on my Desktop
7) Publish to SharePoint (Overwriting the pasted template I created)
This has been my method for years. I do this so that I have a series of templates named with the date, I created them on. This way I can fall back to templates if needed. Or more importantly the items created in the library reference the template they were created with. Allowing me to make changes to the template, make a new version and upload, without changing the items submitted prior. IE: Add a column, change a view, edit a form load rule, etc.. and it only effects items created from that point on.
Either way, this is weird. My research is now into clearing SharePoint Caches and re-running a Crawl. Because if feels as if this is related to cache. I have already restarted the SQL Server (Fall Back to passive), cleared space on the front ends and restarted IIS. So try 137 so to speak, lol.
Good... Bad... Im the guy with the gun.
