you are almost there...

PC pings server OK using IP address, lust takes a few seconds for ARP to resolved.  

PC web browser is OK if you type in IP of server , aka http://208.67.220.220

But if I type in  cisco.com in PC web browser, I get "Host Name Unresolved" error.  So, DNS resolution fails here.

I think I found typo: DNS setting on Router should be 208.67.220.220 , not 220.67.220.220

Yes, definitely a typo: DNS setting on Router should be 208.67.220.220 , not 220.67.220.220.

fix that and refresh IP of PC to get it working.

Thank you! Could you instruct me on how you reached that conclusion?

I noticed difference in IPs after looking at PC settings. No magic here, just look carefully at settings to verify all

Also that did not solve the problem, even when i used the 208 DNS address APIPA is still used

Hello,

odd. I can ping cisco.com with the changed DNS server address (working file attached).

C:\>ping cisco.com

Double check all settings;  After fixing DNS setting, go to PC and refresh its IP address (ipconfig /renew) Or save PT file, close and re-open it.
