I am trying to connect to a remote server and deploy a service there, through a deploy script.

I start by stating "Net use" and send the credentials for the server.

But here I get system 1219 error:

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.

I am not aware that I have any connections other than this one to the server.

I have tried net "use /delete" but was told that no connections were open to the server.

What gives?

1. Fire up a command prompt

cmd.exe

2. View current network shares

C:\>net use
New connections will not be remembered.

Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK           G:        \\srv\share               Microsoft Windows Network
OK           H:        \\fqdn\user$              Microsoft Windows Network
                       \\zombie-srv\share        Microsoft Windows Network
The command completed successfully.

3. Remove zombie mounts

C:\>net use /DELETE \\zombie-srv\share
\\zombie-srv\share was deleted successfully.

4. Mount the share as another user

C:\>net use z: \\zombie-srv\c$ /USER:domain\admin_user
Enter the password for 'domain\admin_user' to connect to 'zombie-srv':
The command completed successfully.

You can also try

net help use
for more details on how to operate the net command.

    net use * /del /yes can be used in a script where you need to delete zombie shares with no intervention. – Jeremy McGee Aug 27 '13 at 16:05

    This was useful, just a small addition: I had started a Admin command window and before coming here already tried net use but it no connections. For some reason I thought to check from a non-admin command window and found a connection that I needed to delete. – Miserable Variable Nov 15 '13 at 16:45
  • this well-written answer should be the accepted one. – Saher Ahwal Mar 16 '16 at 21:20

use IP address instead of server name? (see Multiple Credentials in a Single Windows NT Session http://support.microsoft.com/kb/q173199/ )

This seemed to help: "net use * /del"

Still i do not know what was my initial mistake...

I had the same problem... a connection had been removed, and did not show up in a net use list was preventing a new connection.

Running net use * /del and then answering "N" seemed to clear it!

  • I had to answer "Y". But we had a lot of connections in our list... I think we bumped into some sort of limit, and the error message was not clear. – Mike S Mar 8 '16 at 17:14
  • In Windows, the error messages are never clear. And how to find out what causes the error even less. Not talking about remedy... – Marki May 25 at 13:45

I have found that if I mount a drive, disconnect, and then try to reconnect with different credentials, this error pops up.

net use * /del did not help.

net use shows no connections (checked with both a regular and an elevated prompt)

ipconfig /renew did not help either

I had to log out and log back in. I wonder where these credentials are cached :(

    In case it helps anyone, I found that net stop lanmanworkstation ; net start lanmanworkstation ; net start netlogon ; net start sessionenv did the trick, without logging off. – Jorge Yanes Diez Sep 7 at 11:00

I found this required a combination of net use * /del and disconnecting any previous shared folder sessions on the target server
