Windows NT allows users to connect to multiple resources using multiple user credentials but only allows a single user to use a connection.

If you attempt to connect to the same resource with different credentials, you will get an error message stating that the credentials supplied conflict with an existing set of credentials. If you attempt this operation from an MS-DOS command line, you receive the following error:

System error 1219 has occurred.


Windows NT will attempt to use the same virtual circuit even if a different set of credentials is supplied because the resource name is identical.


Provide the TCP/IP address of the computer instead of the computer name.


It is possible to use multiple user credentials to connect to the same resource on Windows NT when TCP/IP is used as the protocol to establish the connection.

If you connect to the same resource but use the TCP/IP address of the host instead of the computer name, you will be able to connect to the same resource with a different set of credentials.
