I have a server running Server 2003.  The users in the building can connect to it, but I cannot connect to the internet.   This is a server running VM and the other two servers running through VM can access the server.   Any ideas?

Ping is not a reliable test outside of your LAN because many sites turn Ping responses off.  Yahoo.com is an example.  Since 8.8.8.8 is a public dns server for google and google permits ping respnses. - you do get a full response on your ping.

You will find a variety of opinions on this, but some administrators use nslookup to validate internet access.  If you get a full response  on 8.8.8.8, it appears that you do have internet access.  

Are there other symptions that lead you suspect no internet access?

sounds like a dns issue if yahoo.com doesn't resolve but you can ping google dns server by address
what is your dns pointing to?  does anything resolve (like www.google.com?)

As Seth has stated, it's definitely a DNS issue. Change your DNS IP in your NIC to 8.8.8.8 and see if you can connect to the sites previously unable to be contacted. If you can, then you know you either have a DNS server not functioning properly or you have old DNS entries in the server you're currently working on pointing in the wrong direction for DNS resolution.

I changed DNS to 8.8.8.8 and was able to access webpages/downloads I needed.   I am not going to go too deep into fixing this because this server is going to be eliminated in very near future.   So I will keep that DNS address till then.   Thanks
