We had this problem when we went to 10.4. Apple changed to encrypted
passwords. Many windows systems use plaintext passwords. Explanation and fix
from Apple Knowledge Base below. Works for us.

Mac OS X 10.4: Error -36 alert displays when connecting to a Windows server
Mac OS X 10.4: Error -36 alert displays when connecting to a Samba or
Windows server

After upgrading from Mac OS X 10.3.x to Mac OS X 10.4, you may get an error
message when you try to connect to a Samba or Windows (SMB/CIFS) server. A
Samba or Windows (SMB/CIFS) server includes servers operating on Microsoft
Windows and other operating systems that use Samba for SMB/CIFS services.

If the connection is unsuccessful, the following error message may appear:

    The Finder cannot complete the operation because some of the data in
smb://........ could not be read or written. (Error code -36).

If you check the Console (/Applications/Utilities/), you will also see this
error message:

    mount_smbfs: session setup phase failed

This error can occur if your Mac OS X 10.4 client is trying to connect to a
Samba or Windows (SMB/CIFS) server that only supports plain text passwords.
If you do not see the above message in the Console, you are not experiencing
this issue and should try normal troubleshooting to isolate the source of
the issue.

Unlike Mac OS X 10.3, the Mac OS X 10.4 SMB/CIFS client by default only
supports encrypted passwords. Most modern Samba or Windows (SMB/CIFS)
servers use encrypted passwords by default, while some Samba servers might
have to be reconfigured.

You should consider contacting the owner or system administrator of the
Samba or Windows (SMB/CIFS) server to which you are trying to connect and
encourage them to disable plain text passwords and start using encrypted
ones. If the server cannot be reconfigured to support encrypted passwords,
you can configure Mac OS X 10.4 SMB/CIFS client to send plain text
passwords.

Warning: If you configure your computer to allow connections to Samba or
Windows (SMB/CIFS) servers using plain text passwords, when you attempt to
make any connection to such a Samba or Windows (SMB/CIFS) server, your
password will be sent "in the clear". This means that it is possible for
someone who is monitoring your connection to see your password. This could
lead to someone compromising the Samba or Windows (SMB/CIFS) server. We
strongly recommend that you configure your Samba or Windows (SMB/CIFS)
servers to exclusively use encrypted passwords.

Follow the steps below to configure your computer to use plain text
passwords to make SMB/CIFS connections when the specified Samba or Windows
(SMB/CIFS) server does not support encrypted passwords. (You must be an
administrator to do these steps.)

   1. Make sure that you are not currently connected to any Samba or Windows
(SMB/CIFS) servers and that you do not have any Samba or Windows-related
error messages open.
   2. Open the Terminal (/Applications/Utilities/).
   3. At the prompt, type: sudo pico /etc/nsmb.conf
   4. Press Return.
   5. Enter your password when prompted, then press Return again.
   6. You should see an empty file and a "New File" notice at the bottom of
the pico window. If you do not see the "New File" notice, this file already
exists.
   7. Enter the following into the file so that it appears as follows:

[default]
minauth=none



   8. Save the file (press Control-O), press Return, then exit pico
(Control-X).
   9. Type: sudo chmod a+r /etc/nsmb.conf
  10. Press Return.
  11. Restart your computer.
