Not able to connect to internet

I have restarted my server and ASA a couple times.  On my server (only have 1 physical) I am able to connect out to the internet – this is the only machine that can reach the internet.  The weird thing is I am not able to connect to the internet from any other machine inside the network.  I have no idea what could be wrong.  Wondering if the community here can help me diagnose the issue.

You are on to something.  I can access google by IP from a client machine.  Any ideas why this happens and how to resolve it?

It looks like, that there is indeed something wrong with your DNS server.

I need some more information to troubleshoot:

- Were the computers ever able to connect to the internet properly? Or is this a brand new setup?

- What kind of server do you have? Windows 2008 R2?
- Are you running a DNS server on your server?

Yes.  Everything was running okay before yesterday.  It has been running for several years.  Running Windows 2008 R2.   And yes, the server is running DNS and DHCP.

I do not have any records in my Reverse Lookup Zones.  Is this my problem?  Should I create a Reverse Primary Zone (ipv4 Reverse Lookup Zone) with Network ID of 192.168.1 (since my DNS IP is 192.168.1.2)?

Excellent help.  I was missing the PTR record in my DNS.
