Permission to Write Denied

[Selwyn Schultz/Herman Miller]

Users accounts coming in from Windows NT or 95 can read files but get a
message "Permission Denied" when they attempt to create a file or directory
in a shared directory.  The same user can Telnet into the Server using the
same ID and can create files in the shared directory.

I am using domain security with encrypted passwords, and am running Samba
2.07.  The PDC is running on a Windows NT server.

Does anyone have an idea as to why the Windows users cannot create files?
