Folks - I could really use some hints and ideas. Thanks!!! Not less than 3 months ago we had our Solaris 9 samba server working happily. This is with samba 3.0.24 without ads support. The pertinent sections of the smb.conf file follow: [global] # workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH workgroup = mydomain security = domain We created the machine trust acount on the server than used > net rpc join -U administrator%passwd to join the domain. Great huh?! Well, now when we try to access the samba server we get a message saying the trust relationship has been lost. We have tried shuting down and restarting samba numerous time and also deleting and recreating the trust account several times. When I try to run the net join command I get: # ./net join -U administrator%passwd Could not initialise lsa pipe [2007/03/08 08:53:14, 0] utils/net_rpc_join.c:net_rpc_join_ok(70) net_rpc_join_ok: failed to get schannel session key from server <mysrvr> for domain mydomain. Error was NT_STATUS_ACCESS_DENIED Unable to join domain mydomain. Nothing was changed in the smb.conf file and my win admin states nothing changed on his end. Time is sketchy, but he promises the SP1 update to the domain controller happened before the problems started. I'm not convinved. Any ideas and suggestions are GREATLY appreciated. Many thanks, Kris
