Can't log into domain

The original machines have no problem signing on.
when the new address machine tries to log on I get the message "no domain controlleravailable to validate..."

Multiple causes possible. the main suspect should be WINS. Log on locally to the workstation only and try pinging the domain controller first by IP address and then by name. If pinging the IP address does not work then you have a basic connectivity or configuration problem. If the name does not resolve to the IP address you supplied above then the culprit is WINS. Check this out first will watch for further updtes.

The domain is NT4.0 the client is 98
the route has been added to the firewall as well as the rule.

Can you explain how did you add a new address space?
How does tha machine obtain the IP address through DHCP or you assign the IP manually?
If you have DHCP, then check the scope, is it created? and activate the NEW scope,address space(group of Addresses, right?)
then Please check WINS.

Hope this will help

Good Luck

First in network properties on the win98 clients are they configured to ?log in to a NT Domain?? If not you need to set that up with the domain name. Then set up a workgroup for these machines or use an existing group that you already have. Then themachine name needs to be unique for it?s workgroup.
Next you need to have the workgroup on the server, then a machine account and finally a user account.
You may also need to add the servers local IP address to the hosts file for the client, entera ?wins? server address if you are using one and the ?DHCP? server?s address if needed. All of this except the Hosts file is also in Network Properties.
All of this does three things.
One sets up a rout to your server within your network.
Two sets up the necessary accounts needed on your server.
Three tells the client what domain to log on to.

Have u checked your DNS configuration of NT?

If you are using IP enabled routers, make sure they have the new gateway address in them. Check the tcp\ip properties and see if the new gateway is added there. Try statically adding one of the new address and seeing if you get connectivity. Check to see if the new range of addressess and the gateway\router have been added to DHCP correctly.

My I suggest a bigger hammer.....

The people above are on track!!!
