Frustrated with browsing, domains, and network logins ...
I'm trying to get cross-network browsing/domain logins working. In brief, I am very frustrated. We thought the initial problem was a browsing problem, but now it does not appear to be that. Even once the workstation can see the servers, it STILL cannot perform a Domain login, although it CAN access resources if I use the Ms Dos prompt and issue a 'net use ...' command. This happens occasionally with some of our machines, and we are not able to get them to work again once it starts. PLEASE help if you know anything! I am desperate! Also, I tried upgrading to Samba-TNG, but then cross-network browsing broke for about half our clients!??? Did something change with the development branch? Anyway, when we down-graded, most workstations that failed started working again... I have no idea if this is an NT, Samba, or Win98/Win95 issue. Any help is GREATLY appreciated (and I have read the browsing.txt file). Details follow: ******************** Basically, our setup is a follows, We have a WINS server located at x.x.4.1 ->dns1 (Samba 2.0.6) We have a Domain PDC for PLANTSERVICES located at x.x.9.61 -> plant_server (NT 4.0 ServicePack 5) We have a workstation that needs to login to PLANTSERVICES at x.x.5.154 -> dherron (Win98) We are using DHCP for the workstation, and the PDC and WINS (which is a samba Work Group Server for another domain) have static IPs. The Win98 workstation was working fine until yesterday morning, when it stopped logging into the network. This is a symptom that has occurred frequently on campus, and we are VERY frustrated once this starts happening. We are not aware of any changes that were made to either the workstation, WINS, or PDC. In trying to trouble-shoot this problem, I used the following command: [abrock@classroom-dhcp abrock]$ nmblookup -B x.x.5.255 -M - Sending queries to x.x.5.255 x.x.5.131 __MSBROWSE__<01> x.x.5.171 __MSBROWSE__<01> x.x.5.29 __MSBROWSE__<01> x.x.5.179 __MSBROWSE__<01> As you can see, x.x.5.154 was not listed. I then tried: [abrock@classroom-dhcp abrock]$ nmblookup -B x.x.5.255 -M PLANTSERVICES Sending queries to x.x.5.255 name_query failed to find name PLANTSERVICES So, I tried: [abrock@classroom-dhcp abrock]$ nmblookup -A x.x.5.154 Sending queries to 198.106.77.255 Looking up status of x.x.5.154 received 6 names DHERRON <00> - M <ACTIVE> PLANTSERVICES <00> - <GROUP> M <ACTIVE> num_good_sends=0 num_good_receives=0 When comparing this with another machine, I noticed that there was no entries like: DHERRON <20> - M <ACTIVE> PLANTSERVICES <1e> - <GROUP> M <ACTIVE> PLANTSERVICES <1d> - M <ACTIVE> ..__MSBROWSE__. <01> - <GROUP> M <ACTIVE> Also, queries to the WINS server reported: [abrock@classroom-dhcp abrock]$ nmblookup -U dns1 -R -S dherron Sending queries to x.x.4.1 x.x.5.154 dherron<00> Looking up status of x.x.5.154 received 2 names DHERRON <00> - M <ACTIVE> PLANTSERVICES <00> - <GROUP> M <ACTIVE> num_good_sends=0 num_good_receives=0 [abrock@classroom-dhcp abrock]$ nmblookup -U dns1 -R -S plant_server Sending queries to x.x.4.1 x.x.9.61 plant_server<00> Looking up status of x.x.9.61 received 10 names PLANT_SERVER <00> - M <ACTIVE> PLANTSERVICES <00> - <GROUP> M <ACTIVE> PLANTSERVICES <1c> - <GROUP> M <ACTIVE> PLANT_SERVER <20> - M <ACTIVE> PLANTSERVICES <1b> - M <ACTIVE> PLANT_SERVER <03> - M <ACTIVE> PLANTSERVICES <1e> - <GROUP> M <ACTIVE> ADMINISTRATOR <03> - M <ACTIVE> PLANTSERVICES <1d> - M <ACTIVE> ..__MSBROWSE__. <01> - <GROUP> M <ACTIVE> num_good_sends=0 num_good_receives=0 At this point, we re-installed the OS in an attempt to fix the problem, since it seems that this machine would HAVE to be a master browser on this network (there are not other members of PLANTSERVICES on this network). No success. After installation, the problem was unchanged, and nmblookup reports were unchanged. So, in a brain-storm, we turned on file and print sharing of the Win98 workstation. Now, the following appears, [abrock@classroom-dhcp abrock]$ nmblookup -U dns1 -R -S dherron Sending queries to x.x.4.1 x.x.5.154 dherron<00> Looking up status of x.x.5.154 received 6 names DHERRON <00> - M <ACTIVE> PLANTSERVICES <00> - <GROUP> M <ACTIVE> DHERRON <20> - M <ACTIVE> PLANTSERVICES <1e> - <GROUP> M <ACTIVE> PLANTSERVICES <1d> - M <ACTIVE> ..__MSBROWSE__. <01> - <GROUP> M <ACTIVE> num_good_sends=0 num_good_receives=0 However, we still have the same problem when trying to login to the PDC. On the other hand, if I turn-off the 'Logon to Windows NT Domain' in Client for Microsoft Networks, I am able to login to the machine, but cannot see any other machines in the domain. If I then open an MS DOS PROMPT, and issue: net use w: \\x.x.9.61\netlogon it will successfully connect! After is successfully connects, I can then see all the servers in the domain, like I am supposed to. However, if I then log off, I STILL can't login to the domain, but the list remains in Network Neighborhood. What is going on? Does anyone have any idea why this workstation cannot login to the domain? How to I get cross-network browsing to work BEFORE issuing the above command? Thanks in advance for any help, Tony Brock ****************************************************************************** * Anthony Brock abrock@georgefox.edu * * Director of Network Services George Fox University * ******************************************************************************
