Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed.

Question

Hello,

There is some weird behavior with Windows 11 that I do not experience in Windows 10. I have a samba server with two shares that I setup as mapped drives. One share is public that requires no username/password. The other share does. I can connect to both fine one at a time. If I map one share via the DNS hostname, then try to the other using the DNS hostname, it give the error, "System error 1219 has occurred. Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again." If I connect to one share using it's DNS name and the other using the IP of the same server, I'm able to map both without issue. I'm curious as to why Windows 11 will not allow me to make multiple share connections to the same server using the DNS name? Is this a bug? Is there a way to make Windows 11 allow simultaneous connections using the DNS name? Windows 10 doesn't have this issue.

Hello,

Thank you for reaching out.Regarding the issue you're encountering in Windows 11 with the error message "System error 1219 has occurred," this typically means the system believes you are trying to connect to the same server or shared resource using the same credentials, resulting in a conflict.

In Windows 11, there seems to be stricter connection management, especially when using DNS names. Compared to Windows 10, Windows 11 may restrict multiple connections with the same username through DNS names.

Here are a few solutions you can try:

1. Clear Existing Connections: Before trying to connect to new shares, it’s recommended to disconnect any current network connections. You can use the following command in Command Prompt to clear existing connections:

net use * /delete

1. Use Different Connection Methods: If you connect one share using the DNS name and another using the IP address, this should help avoid the “multiple usernames” error. You can try connecting using the IP address or DNS name to resolve this conflict.
2. Manually Map Network Drives: You can also try using the net use command to manually map the network drives, specifying different usernames and passwords. This will help prevent Windows 11 from treating the connections as “duplicate connections”:

net use Z: \server\share /user:username password

1. Check Network Settings: Ensure that your computer has network discovery and file sharing enabled, as these settings could impact the stability of your connections.
2. Check for System Updates: Windows 11 might have some known bugs or limitations, so please ensure your system is up-to-date and check if any patches have been released to address this issue.

If these methods don't resolve the problem, you may want to contact Microsoft support for more solutions or fixes related to this issue.

I hope this information helps! If you have any further questions, feel free to ask.
