Terminalserver webdav systemerror 1219

Hi,

i try to mount a nextcloud installation via webdav on a windows terminalserver 2016.
When the first user connect via gui or cmd "net use * https://xxx.yy/remote.php/dav/files/USERNAME it is no problem with entering credentials.
When the next user login and try to connect, he get the error message “ERROR_SESSION_CREDENTIAL_CONFLICT”
or in german:
“Mehrfache Verbindungen zu einem Server oder einer freigegebenen Ressource von demselben Benutzer unter Verwendung mehrerer Benutzernamen sind nicht zulässig. Trennen Sie alle früheren Verbindungen zu dem Server bzw. der freigegebenen Ressource, und versuchen Sie es erneut.”

It is not a nextcloud prolem, it seems to be a windows problem connecting with multiple users.
How can i solve this? I try “Raidrive”, but it is slow and is limit to 5 concurrent connections.

When i try with both users to mount “net use * https://xxx.yy/remote.php/webdav” the second user ist not ask for creditials and the letter is mounted, but when he try to connect, he gets “access denied”

Are there some registry keys to weak?
Whats best practice with terminalserver and webdav?

I do not wont to sync the files locally.

Thanks in advanced

It is not a nextcloud prolem, it seems to be a windows problem connecting with multiple users.

If you search for the given message on the Internet you will find several matches, one is eg. this one:

I have searched for this and this is easy when you connect a samba share… I can do this for nextcloud too, when i create aliases and add them in the config to ‘trusted_domains’ => array.
This is a windows terminal server and there are different users connected via rdp sessions. I thought that every user is isolated, because this works to connect to the same samba share with different username, but not with webdav.
Did nobody else use webdav on a windows terminalserver 2016?

thanks in advanced
