Windows 7 Pro can't join to Windows Server 2003 domain server



Windows 7 Pro can't join to Windows Server 2003 domain server, error message
as follow:

"Your computer could not be joined to the domain because the followingerror
An attempt to resolve the DNS name of a DC 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."

Windows 7 can ping the Windows 2003 server, all machines ip & dns settings
are from dhcp server,
but Windows XP machine is all fine to join the Windows 2003 domain server.

I google the problem, found that some ppl has the same problem with Vista.
Anyone has similar experience?


.. Ray,

Have you solved your problem yet?

I have found a fix for me. I have had to disable or lower the NTLM security.
From windows 7, click start, type local and open the Local Security Policy

Select Local Policies -> Security Options, in the right find Network
Secuity: LAN Manager Authentication Leven, and set to Send LM & NTLM - use
NTLMv2 session security if negotiated.

Hope that helps
