Netlogon no longer works in 2.2.6 with W2k client
Hi, We've got a fairly simple samba setup (no ldap/winbind etc) and until recently everything worked fine (using samba-2.2.5). But after switching to samba-2.2.6 w2k-clients fail to run the netlogon-scripts. When i look at the client it says: logonserver=\\<workstationname> BTW. The output of "nmblookup -S CPB" (to me) seems to say that CPB is the logonserver. querying CPB
