Which version of pfSense?
Is this a new install or was it working well before?
What exact ipconfig command did you run and why?
Which client PC are you talking about?  You never mentioned a client.

on Client PC i coud not find my home domain name

What do you mean here?  That you couldn't resolve your domain name, or that you couldn't access a resource based on its domain name?

and  after turn off and on my connection to internet was DC

???

If you could answer my questions and explain a bit more the problem you are having, then maybe we could make some progress.

If I understand you, you're saying that your client is having a problem getting a DHCP lease from your Windows 2012 server?  I'm not sure what pfSense has to do with it.

Running ipconfig is going to show you your network connection details as given by your DHCP server.  pfSense isn't even involved unless your client is going out onto the Internet.

Just because I'm curious, what does your client have for IP address, netmask and gateway?

The first problem is the pfsense don't connecting to internet its take DHCP IP from my ADSL but when i Ping there is not internet in pfsense side

What are you pinging?  Can you get to the WebGUI and configure pfSense?  Can you ping 8.8.8.8 from Diagnostics - Ping?
