Anyone have any ideas about the following problem. We have a W2K Advanced Server as a PDC in a domain: WINDOMAIN And we have a Samba 2.x server as the PDC (through LDAP & PAM) of another domain: LINUXDOMAIN Any computer in WINDOMAIN can access shares on any computer (Linux, Windows, etc.) in LINUXDOMAIN (provided the appropriate credentials are used for LINUXDOMAIN) except the W2K PDC. No matter what, it cannot access any shares in LINUXDOMAIN. It just keeps reasking for the login and password, saying that the previous login/password attempt was: "Incorrect password or unknown user name for:" NB: We also have an NT4 domain: NT4DOMAIN, which the W2K PDC accesses just fine. Of course, I use the convention LINUXDOMAIN\username for logging in. Any input would be most appreciated. Thanks!
