When I map network drive I chose "connect using a diferent user name" and enter user name and password of the network disk I want to conect to. But when I restart windows, at startup displays window : "Incorect password or unknown user name" and I must enter password for network disk again. Computer don't remind the password for network disk. What am I doing wrong ?

Does the drive map successfully when you first attempt to map it? Are you selecting the option to "Reconnect at Login" and also logging in with the same username (profile) under which you originally mapped the drive?

The problem is his logon credencials don't match the ones used to establish the share connection. No solution to this that I am aware of. Unless you could do it from your network logon script instead of Explorer and provide the credencials there in the script.

you can use the net use command for startup script.its command can write down different username before map drive
