Windows 7: Cannot connect Win7 Client to SBS2003

Cannot connect Win7 Client to SBS2003

I am trying to setup a client computer running Win7 to SBS2003. I hve setup the name on the server, I am using a user with admin rights, I have the servers ip as the primary DNS on the router, I have put that IP of the server on the primary DNS on the client computer. I run the connectcomputer and the screen comes up that allows me to put in the name and password and once I hit ok I get an error saying that the list of computers and users cannot be found. I can ping the server, I can map the network drive to it, I can remotely log in to it from the client computer as well. I have unchecked the ipv6 adapter and I have run all these steps with the firewall disabled or enabled. I have tried changing the domain under the computer properties and it asks for the login information and I get an error stating: An attempt to resolve the DNS name of a domain controller in the domain being joined has failed. I have XP clients that I setup already that connected with no problems. Ive tried about every suggestion that has been posted? Does anyone have any other ones? I have also downloaded the hotfix and updated the server.

Windows 7 Ult, Windows 8.1 Pro,

This requires that you change the lanman server parimeters in order to get Windows 7 working with older servers. Do these adjustments on the Windows 7 machines that need to connect to the server.

I'm not sure if this has to do with your exact problem but these adjustments are usually required to get Windows 7 working with older servers.

Control Panel - Administrative Tools - Local Security Policy

Local Policies - Security Options

Network security: LAN Manager authentication level
Set to Send LM & NTLM responses only

Set the Minimum session security for NTLM SSP
Disable Require 128-bit encryption

The screen shots below should be helpful.

Reboot all machines after making the adjustment.
