Morning all. Im hoping someone here has seen this before and can suggest a solution. I added a Samba 3.0.5 box to our AD yesterday and now one of our DCs is producing the following error in its System log: Event Type: Error Event Source: Server Event Category: None Event ID: 2510 Date: 20/08/2004 Time: 2:24:05 AM User: N/A Computer: RKI-SYD-SQL1 Description: The server service was unable to map error code 1355. The occurance of this error appears to be very random. According to MS this means: H:\>net helpmsg 1355 The specified domain either does not exist or could not be contacted. The MS KB has a few references for Event ID 2510 but nothing specific for error code 1355. Google groups found: http://groups.google.com/groups?q=windows+2000+event+id+2510+1355&hl=en&lr=&ie=UTF-8&selm=i5T9AVzkDHA.2616%40cpmsftngxa06.phx.gbl&rnum=2 Seems like a contender and suggests the problem is a Samba one. Im unsure how to proceed though, ive probably not got Samba setup right. Anyone else seen this error? start smb.conf [global] # general options workgroup = *REMOVEDTOPROTECTTHEINNOCENT* netbios name = SERVER1 server string = Server 1 # winbindd configuration #winbind separator = + idmap uid = 10000-20000 idmap gid = 10000-20000 winbind enum users = yes winbind enum groups = yes #template homedir = /home/%D/%U #template shell = /bin/bash # Active directory joining security = ads encrypt passwords = yes realm = *REMOVEDTOPROTECTTHEINNOCENT* wins server = X.X.X.35 cheers Andrew -- NARF! 250 OK
