Sorry about the missing information yesterday. I'll recap the problem and then fill in all the questions Charles was kind enough to enumerate. Problem: added a Red Hat/Samba box to a Windows network and a new problem started. Windows machines that logged out and then back were unable to browse AND unable to map drives. The machines that were logged in before Samba booted continue to work fine. We've repeated the experience a couple times to make sure we understood the symptoms. New Info: The Samba box is not a PDC. One of the Windows/NT boxes is the PDC. The Samba box is not a WINS server. Again one of the NT boxes is. (Possible problem. I haven't set the WINS server in the smb.conf file yet) The Samba box is not a DHCP server. One of the NT boxes is. The Samba box is also NOT a DHCP client but has a static IP. I'll continue trying to pinpoint the problem but I was hoping that if you've seen this problem you could help point me in the right direction. Thanks. --*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Scott McLeod scottmcleod@mediaone.net
