Hi techies,
The secretary of my most hard to please client called and after 10 minutes back and forth I managed to get that her boss was unable to logon.
When he attempted logon he gets a message stating that there is no logon sever available to validate the password.
Like I said this is my most hard to please client and I don't want to go down there thinkiing I can easily solve the problem and find out I can't.
The facts are that he is running a 98 machine and the server is NT. The server is working fine as other non 2000 machines can be seen. No one else has this problem.
When I go over there I'll look at
1) his network point, see if I can logon with my laptop from that point.
2) Is the server really up and running (its hard to get technical info some people)
3)Check his tcp/ip settings to see if anyone has been playing around with it.

Is there anything else I should look at ?

Hi,
In network properties you can check many other things:
-identification: workgroup must be the same like your domain name
-access control: use "user level access control" and also type your domain name.
-client for microsoft network properties: mark "logon to windows NT domain"
-network logon options: "logon and restore network connections"
Also you can force users to use Logon Screen appling this patch:

Ping servers when problem occured.

Along with Florindel's suggestions you might want to check his IP address if he has a laptop and make sure it is good for your network. You can verify by the third octet it should be the same as the people on his floor...if it is different then clear it (ipconfig /release)and then reboot. You can try "ipconfig /renew" and see if it will renew it but I found sometimes it doesn't.

ping first! with luck, it won't work. otherwise nic and at least part of tcpip is ok... if i could ping but couldn't logon i think i'd look at the nic speed and lock it down to 10MB, especially if they can logon sometimes, like right after a reboot.if not ping: verify the patch cable. take a known good one and swap. 'ask, when did it work ok last? has anything changed? has this ever happened before?' i know, it's another 10 minute garbled conversation but think positve listen, you might pick upmore work as some other problem gets remembered... look for simple solutions first imho. also consider swapping ports at the hub end. (make notes about what is plugged in where). I have a really long (out of spec long) patch cable i use to swap out wall outlets to eliminate the wire in the wall as a problem... test, if you get a bad result, retest. could be a bad nic but more probable a bad cable imho. good luck.

I would check everything from the server end first (before announcing your presence to the difficult client if possible):

Is the server up and running?
If IP addresses are dynamically assigned, has a DHCP lease been issued for your clients computer?
Can you ping your clients computer from the server?
Do you have a connection light at the switch/hub for your clients segment?
Check and make sure your clients user account isn't locked out!

Now go see your client if no fixes were apparentat the server:
Have him try to log-on in your presence. The answer could be as simple as telling him "Make sure you spell the domain name correctly."
If you could ping his computer from the server, connectivity isn't the issue.
Try logging in onhis computer using your admin user ID and password.
Progress from there troubleshooting possible network settings issues or connectivity issues.

Always try and check the easy stuff first.

maybe license manager has revoked his use. Check to see if you need to add more licences from within the control panel.
