I looked at the Network Adapters screen in the Configurations tab and noticed that only 3 of the four installed NICs are present. I had four last week, The missing NIC is an integrated Broadcom nic that came with the Dell 2950 server. The server came with two of them and the other is working just fine. I have lights on the backs of them all and yet the OS does not see it. I have run esxcfg-nics -l to list the nics and only three come back. The other 2950's in the farm are set up the same and show all four nics. I updated this server with all patches and still no luck. Any further ideas?
Inside the esx.conf file I see:
/device/005:00.0/name = "Broadcom Corporation Broadcom NetXtreme II BCM5708 1000Base-T (rev 12)"
/device/005:00.0/options = ""
/device/005:00.0/owner = "vmkernel"
/device/005:00.0/subsysDevID = "01b2"
/device/005:00.0/subsysVendor = "1028"
/device/005:00.0/vendor = "14e4"
/device/005:00.0/vmkname = "vmnic1"
/device/006:00.0/class = "060400"
/device/006:00.0/devID = "3500"
/device/009:00.0/name = "Broadcom Corporation Broadcom NetXtreme II BCM5708 1000Base-T (rev 12)"
/device/009:00.0/options = ""
/device/009:00.0/owner = "vmkernel"

/device/009:00.0/subsysVendor = "1028"
/device/009:00.0/vendor = "14e4"
/device/009:00.0/vmkname = "vmnic2"
/device/010:00.0/class = "020000"
/device/010:00.0/devID = "105e"
/device/010:00.0/irq = "17"
/device/006:00.0/class = "060400"
/device/006:00.0/devID = "3500"
Anything odd showing up in the logs?
ESX may have discarded this nic because the hardware was faulty...
Which log?
If you can access the console, look at /proc/vmware/log or /var/log/vmkernel and search for lines related to the missing vmnic's name.
