From the windows 7 PC I can see the other PC's on the network, can see the server, can access the shares on the server, and remote into the server. I can also ping the dns server. There are 2 ways to join the domain. The first one used a wizard on the windows 7 PC. When I go thru the wizard it tells me that there is no account on the domain controller for the PC. If I do it manually it tells me the dns couldn't find the controller. The dns server is the domain controller. I have also tried using a static IP like the XP machines have and got the same problems. I have also created the computer account on the server manually
The server has sp2 installed. I have looked on the net and found some different solutions like making changed to the local security policy but none of those have worked. I am stumped. Anybody know of a solution?
This should allow to join from the Windows 7 PC. Disabling the 128 bit encryption is usually required.
Control Panel - Administrative Tools - Local Security Policy
Local Policies - Security Options
Network security: LAN Manager authentication level 0 Send LM & NTLM responses
Minimum session security for NTLM SSP Disable Require 128-bit encryption
Here are all the different levels of NTLM security.
0) Send LM & NTLM responses
1) Send LM & NTLM - use NTLMv2 session security if negotiated
2) Send NTLM response only
3) Send NTLMv2 response only
4) Send NTLMv2 response only. Refuse LM
5) Send NTLMv2 response only. Refuse LM & NTLM
I also heard that using the same DNS as the server may help.
