Hello, I'm an Information System admin. We have a bunch of PC with Windows NT 4.0-SP1(Service Pack 1). Then I'm going to upgrade them to SP3 maybe soon. I set up Samba server at SunOS 4.1.3 without password encryption. My question is, can survive both SP1 and SP3 with pw encrypted Samba server simultaneously? Or, how do I upgrade NT4-SP1 into SP3? I can't imagine upgrading procedure yet. Do you run 2 Samba server processes with and without pw encryption? Please let me know detail. Thank you very much, Yoshiaki Ueda Cognex Corportion, MIS
