Hello,
We are having an issue in our environment that we haven't been able to resolve. We are running Windows Server 2012 R2 terminal servers and users are using Roaming profiles. The issue we are having is that if there is more than one PDF viewer installed on the terminal servers (Adobe Acrobat and Adobe Reader for example) when the user chooses a default PDF application, once they log off and back on, that default preference is lost. They once again have to select their default PDF viewer, every time they log in. If there is only one PDF application installed on the server, the setting is retained without an issue. Also, if you use a local profile, even with multiple PDF viewers installed, the default setting is retained without an issue. We've tried using GPP to set the registry key to set the default viewer, however, the value has a Deny Write value applied to it. We've also tried scripting an export and import of they key upon logoff and logon respectively, however, the same issue prevents that (the deny write value on the registry). HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf\UserCh oice\Progid
We've contacted Microsoft support, and they told us this was a 3rd party issue because the only file extension with this problem is the .pdf file extension. We also setup a test environment with only roaming profiles GPO setup and were able to duplicate the issue and make sure there wasn't a GPO causing this problem. Any help or guidance you could provide would be appreciated.
Thanks,
Adam
