are you saying that your server cannot even ping any other machine in the same VLAN ? Can you post the configurations of your switch and your Layer 3 (if you have inter-VLAN routing configured as well) ?
Slight chance that your server is stuck with an old route in its routing table, you might want to issue the command:
to flush the internal routing table of your server.
Once I removed the dual NICs from the server, I am able to see part of my network. I am still having trouble seeing the DNS. Another computer on the same VLAN in the same switch can see the DNS fine. Here are my configs. Any help is appreciated.
First determine if this is a Layer 1,2 or 3 issue. Then focus on that Layer to troubleshoot. I.e check to see errors on that port to see if this a Layer 1 issue, then do "sh cdp neighbor" to see if the access switch can see the gateway, and so on.....try to gather as much info as possible...then troubleshoot.
