Just for clarification: The environment which I was able to get roaming profiles: All user workstations are running Windows NT 3.51 The NT Server (PDC) is running NT Server 4.0 The samba version is 1.9.16p11 on Solaris 2.5 Key points: Need to use encrypted passwords, and (for me at least) use "security = server" with "password server = <PDC>". Thanks again to Tom Lieuallen and Luke Kenneth Casson Leighton. Jeff
