i got the user name, domain and password. how can i write with credentials?
if i already been to that computer in this session there is no problem, but if it's a new session the computer doesn't recognize the location

how can i write with credentials?

What identity do you want to pass to the remote server? The application identity, the identity of the user using the application, or something else? — Paul Turner, Jul 26 '11 at 11:46
Try to remove the @ `(i.e StreamWriter("\\" + remoteMachine...) )` — Mark Segal, Jul 26 '11 at 12:10

You'll need to impersonate the identity before using the StreamWriter. WindowsIdentity.Impersonate Method article has a great example of doing so.

Inside this code you would use the StreamWriter:

using (WindowsImpersonationContext impersonatedUser = newId.Impersonate()) {
    StreamWriter(@"\\" + remoteMachine + "\\admin$\\" + fileName);
}

what is `newId`? – Si8 Mar 16 '18 at 18:29
@Si8 It's an instance of `WindowsIdentity`. – Yuck Mar 16 '18 at 18:41
