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

Answer 1

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);
}
