Broken link, archive.org doesn't have it either :( This might be a similar technet article? learn.microsoft.com/en-us/archive/msdn-technet-forums/…

I wonder if a local group policy setting may be causing the issue? gpedit.msc, right-click administrative templates, Filter Options, Configured=Yes, OK, expand admin templates, click All Settings (under Comp config & User Config)

Maybe try adding the DFS/file-server path to Office trusted locations. GUI: File, Options, Trust Center, Trusted Locations. GPO: User Configuration/Administrative Templates/Microsoft Office 2016/Security Settings/Trust Center--Trusted Location #1

I've love to start RSOP.msc attached to remote PC (to trigger in a script) & haven't found a way to do it from the command-line. If anyone knows how to do it I think it'd be a helpful to put in a comment
