Unable to save a checked out PDF back to Sharepoint site
Hi,
We've recently come across a problem with saving markup changes to PDF's in a particular subsite of an internal Sharepoint farm. We get an error message that "Adobe Acrobat Reader DC cannot access the network. Please verify your computer's network connection and try again.
We can access the site by adding the Sharepoint site account manually with Acrobat, so connectivity is not an issue.
Other sites are unaffected, and it's not a permission issue as users can manually check the document out locally, then check back in with changes no problem. It seems to be a problem specific to Adobe as other PDF readers (Nuance, CutePDF) do not have this problem.
Sharepoint site is present in IE Trusted sites, Protected mode has been disabled as a test. I've gone so far as to run procmon/wireshark traces but cannot see an issue with what Acrobat Reader is doing differently that would cause it to report a "network problem". Searches of this forum and the internet have not found any other similar reports of this issue.
Desktop clients are running Adobe Acrobat Reader DC 15.023.20070, but have also tested with latest release with no change.
Hoping anyone can help shed some light on this. We're not sure Microsoft can/will support as the Sharepoint farm is working.
Thanks
Justin
