No domain controller found (sometimes) H

You have an intermittent NetBIOS name resolution problem. The machine is your problem not the users.
Check your lmhosts files. Check your WINS server, if using it. Check the binding order of your protocols if using more than TCP/IP.
Have yourusers wait for about 10-15 seconds after turning on the computer and attempting to logon. It takes a finite amount of time for the system to come on line and obtain the proper name resolution before logon can occur. The more switches and hubs between your computer and the DC the more time it takes to resolve the name to IP address.

Can you tell me more regarding what should be in the lmhost file
we are running only tcp/ip and no hubs

Prevoiusly I had same problem for my customer. And I install WINS on NT Server, and delete unused protocol on both NT server and client workstation. Specially I stopped protocol NetBEUI. It works.

Two more suggestion,

1. add following commandline into lmhost on the windows98 workstation.

xxx.xxx.xxx.xxx servername #PRE #DOM:domainname

2. change the Network Card.

Hope it can help.

Hi,
I do wonder regarding your server. Do you have 2 or more server ? Shouldn't 125 users having at least two domain controllers (primary and backup) ?
Have you checked the network utilization ? Simple method would be using the Task Manager (or isthat Performance Monitor) ?

Have you confirmed that their WINS settings are correct? If they are using DHCP, you can still manually enter the WINS IP addresses. Also, as someone else suggested, remove the unused protocols that typically are installed, like netbeui and IPX/SPX. Leave only TCP/IP.
