I am trying to use the following command to map a drive in persistent mode, and I don’t want it to ask for login credentials every time the machine is restarted:

net use P : \\server\folder Password123 / user : user123 / savecred / persistent : yes

The error is as follows:

A command was used with conflicting switches . 
More help is available by typing NET HELPMSG 3510 .

When we use the /savecredswitch we should not provide credentials in the same line. The correct command should be:

net use P : \\server\folder / savecred / persistent : yes

It will ask for username and password.
