Sccm 2012 R2 - Windows 7 not listening on Port 80

Question

Hello,
In looking through smsts.log and IIS logs I saw a lot of error communicating on Port 80.  When  tried to telnet from a pc to our sccm 2012 server using port 80, it goes through fine. But when I tried it the other way around, it fails.  When
I ran netstat -an |find /i  "listening" on my pc and others around me, I discover port 80 isn't listening. The firewall is off on both the pcs and sccm primary server.  Port 80 isn't blocked on the network.

I was told something has to initiate port 80 being open on win7.  Is this true? If so, any idea why sccm isn't doing this? I could switch to port 8530 (have to do this for wsus too), but would think networking would have to open this port and then again,
would the pc listen for it?
PS, The sccm position before this one,  dealt with Servers, that must have had port 80 listening.

Answer 1

After installing SCCM client via Task Sequence, and rebooting, the Self-signed certificate never comes down so the other Action items in Cinfiguration Manager Properties never come down.  The only way I can get the Certificate to come down (seen in
MMC) is to give full permission (No one had rights initially) to rsa keys folder, delete smscfg.ini file and restart the sms host service.  But if you go into configuration manager properties the client certificate is still shown as None. The locationServices.log
shows :failed to send management point list location request message to Primary Server/MP. If try
http://PrimaryServer it fails to connect from a pc. But if I try it from the primary server sccm01 it works fine. Port 80 is open on the network. 
smsts shows:
 Sending with winhttp Failed; 80072ee2  and also socket connect failed; 8007274c
Is there any other logs I can send you to help resolve this?
Again, Thanks so much for all of your help!!!
