My Windows 7 machine, is configured with the below settings:

To make sure that your PC can reach your domain controller properly, try to ping your DC, this will ensure that your PC is able to communicate with the DC, and hence can properly join it.

To join Windows 7 to a Domain, follow these steps:

Click on Start > then right click on Computer and click on Properties
The basic system information page will open, under Computer name, domain, and workgroup settings, click on Change Settings
On the System Properties page, click on Change...
Under Member of, select the radio button beside Domain: , type the name of the domain you want your Windows 7 to join and then click OK

A confirmation pop up box will welcome you to the domain. Clicking on OK, will result in having another message informing that a reboot for the machine is required to apply the changes. Click on OK

Close System properties page, and on the You must restart your computer pop up message box, click on Restart Now
Once your machine is rebooted, press CTRL + ALT + Del to log on

Click on Other User
Type your domain user credentials and click on Enter key to log on. Note that, as seen in the below image, my domain name is stated under the username and password textboxes. If it happens that you have your local machine name is shown and not your domain name, then type the user name in this format : domain name\username

If you want, after you log on to the machine, open the basic system properties page ( Right Click Computer > Properties ), and check your computer full name, and the name of the domain your machine is joined to.
