A cause for the pesky -36 error with SMB connections

I get these on occasion, though I do much less with XP these days ...

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.

I think XP only uses encrypted passwords, but I'll check.
