Server migration and DNS

[PrimaryTech]

HI all,

 

I've recently got a new server to replace our aging domain controller and I've been going through the process detailed here:

 

Step By Step Guide for Migrating Windows 2000 server to Windows 2003 Server | Windows Reference

 

So far I've done 3 of the 4 steps: New server is on the domain and holds all 5 FSMO roles plus the GC role, I've migrated all shares and transferred and authorised DHCP.

 

Did all the checks with DCDIAG's, all fine.

 

Before demoting the old (Server 2000) server I thought I'd see if a client could log on with the old server removed from the network (took the network cable out of the server). The client connected to the domain but was ssssllllooooooowwww, around 8-10 mins to log on.

 

I researched the problem and found that the clients have the old server's IP address as the DNS server

 

If I demote the old server to a member server and remove it from the domain, give the new server the same name and IP address as the old server as described here

 

(Disconnect the old server (win server 2000),Raise the domain level functionality to native Windows 2003,Rename your new windows server 2003(Part4) | Windows Reference)

 

Will this cure my really slow logons?

 

Sorry it's a long post, any help/guidance is gratefully received!

If you have DHCP on the new one why not configure DHCP to be using the new one's IP for DNS and reboot the PC?

What he said, in the DHCP configure it so the DNS points to the new server. Have you installed DNS on the new server?

[PrimaryTech]

Thanks for the replies, yes DNS is installed on the new server. How would I configure DHCP to point to the new DNS server? Sorry but I'm a n00b to server migrations. Kmount, do you mean reboot the client or the new server?

Thanks again!!

Is it server 2003?

 

If you go into your scope options inside DHCP on your DHCP server you will find DNS in there. Off the top of my head i can't remember the exact place.

The client.

 

In your DHCP scope (I assume you've set up the ranges etc?) there's an option for DNS.

 

This might help?

Thanks again guys, kmount that link was just what I was looking for, all the DHCP scope and reservations were imported from the old server using DHCPEXIM.

I'm on half term next week so I might go in and see if I can change the settings get the clients logging on.

Oh, an the new server is Server 2003.
