Hi experts,

Recently I have installed windows 2003 server. I added the 2 workstation in to the domain but I donno why it is taking much time to authenticate .

I think my problem is something related to DNS. Here is the link I was looking at, but was not sure how to do it.
 http://www.experts-exchange.com/Operating_Systems/Windows_Server_2003/Q_21455799.html?query=windows+authentication+is+too+slow&topics=666

The problem seems to be same as mentioned in the above link. I would greatly appreciate if someon could help me resolve this issue.

Thanks,
Sundeep.

The DNS on the server should point to itself as it should (will) be running DNS active directory integrated assuming you are running a domain, I use the IP address of the server, others use 127.0.0.1 but consensus tends to be use the server's real IP.  Don't put ANY other DNS server IP addresses in there unless you have another AD server running DNS too.

Your clients should point only for DNS to the server's IP address, generally using a DHCP server to push out the settings.

You then setup forwarders in the forwarders tab of the properties of the DNS server in DNS management console to point to two or more DNS server addresses supplied by your ISP.

That *should* be it.

Ask if not sure.

hey Steve,

It already has the forwardings. I don't know why it is so slow while logging in.  
here is the figure  of DNSmang console properties......
http://www.phys.lsu.edu/~sundeep/DNSmang.JPG

I guess I made some mistake in domain name assigning.  Mycomputer name is fserver and the domain name is mainoffice.phys. So i can see the full name of the computer as fserver.mainoffice.phys , while most of the computer's fullname in the department look like "mac.phys.nmsu.edu" . do you think  i need to change it to something different??
please give me some ideas

Thanks

Sundeep.

When i do nslookup I get

****************************
> nslookup mserver.phys.nmsu.edu
Server:         130.39.3.10
Address:        130.39.3.10#53

Name:   mserver.phys.nmsu.edu
Address: 130.29.10.17
*******************************

This is the name that has been assigned to the ethernet. As you can see the computer name is different from this name.  
Any mistake??

Please explain the IP of your server, the workstation and the dns server currently defined for each.

The workstations should have the dns server entry in tcpip properties of network card set to the server in the domain they login to unless this is part of a bigger organisation ...

Will look back later. Off now

OK.  Is this server a domain controller of your own for your own domain? Is this part of a forest on the rest of the site or just your own seperate one? If so then from you setup there is it clear what is wrong.

Server.  IP 130.29.10.17.  Subnet mask 255.255.252.0   Gateway 130.29.10.1  DNS 130.29.10.17
PC. IP 130.29.10.18 subnet mask 255.255.252.0  gateway 130.29.10.1  DNS 130.29.10.17

On Server.  In properties of DNS the server go to the forwarders tab. Add in 130.29.3.5 an 130.29.244.30 to forward on any request to presumably the DNS servers for the rest of the site.

Unless you have another AD server running the DNS for your domain do NOT add another DNS server to the clients.  They must ONLY have ones that point at your domain.

Try that for now, I think it should be OK, if not let me know.

Thanks steve,

it seems to work fine using the following configuration
Server.  IP 130.29.10.17.  Subnet mask 255.255.252.0   Gateway 130.29.10.1  DNS 127.0.0.1
PC. IP 130.29.10.18 subnet mask 255.255.252.0  gateway 130.29.10.1  DNS 130.29.10.17

but  got a problem with the firewall, when I turn on the windows firewall it again does the same thing , takes atleast 3 mins to login

any ideas??

thanks
Sundeep.
