Ok, here is the code as it stands currently.
Note that "password" has been replaced for seurity reasons.
Also note that I'm using LOGON32_LOGON_NEW_CREDENTIALS (9) now which threw a
SecurityException "Unable to impersonate user" instead of
LOGON32_LOGON_NETWORK_CLEARTEXT (8) which gave the 1326.

private void button1_Click(object sender, System.EventArgs e)
{
int token;
WindowsIdentity wid_current = WindowsIdentity.GetCurrent();

kernel.LogonUser("Administrator", "192.168.0.5", "password", 9, 0, out token);
int ret = kernel.GetLastError();
if (ret != 0) { MessageBox.Show(ret.ToString(), "Error"); return; }

// Code after this doesn't get executed yet
                        
IntPtr admin_token = new IntPtr(token);
WindowsIdentity wid_admin = new WindowsIdentity(admin_token);
WindowsImpersonationContext wic = wid_admin.Impersonate();

System.IO.File.Copy("C:\\test_read\\test.txt",
"\\\\192.168.0.5\\trent\\test.txt", true);
wic.Undo();
}

I would love to assume that I'm getting somewhere now that I'm getting a
securityexception.

Thanks for your help so far Willy.
