Windows 7 connection to Server 2003

cannot connect windows 7 to a server 2003
 "An attempt to resolve the DNS name of a domain controller in the domain being joined has failed. Please verify this client is configured to reach a DNS Server that can resolve DNS names in the target domain."
What edition of Windows 7?
Only Professional, Ultimate and Enterprise editions can join a domain.
----------------------------
This is either the DHCP is not configured properly to give the computer the proper DNS or you are using a static IP and have specified the wrong DNS or simply your DNS cache has not been updated. Lets start with the last one and work our way up. To refresh the cache do...
ipconfig /flushdns
ipconfig /registerdns
You have to do this with elevated rights in Windows 7 so right click in the Command Prompt and select run as administrator.
Then you can see if it is resolving your DC by doing a ping...
ping yourdomainname.local
If it does then try joining if not then look at what is specified in the DNS of your...
ipconfig /all
If it is not your primary Name Server then look at the network connections to correct it or look at your DHCP settings.
You may want to do an NSLOOKUP to make sure the computer is seeing your Name Server and not another.
You may also want to look at your DNS server to make sure the host for the DC is registered.
