VMware Server 2 \ VMclient reports "Network Cable Unplugged"

Server Hardware is a Dell Poweredge 2650 Dual 3.06 W/ 12 gb ram running 2k3 Enterprise.

I am unable to get the networking to work from the VM to my corporate network. There are no restrictions on the corporate network preventing this, as similar setups are working fine on other machines. (10 VMware Servers total, 60 VM's)

When I run the new VMWare web console, I start up the VM and it boots fine into its guest OS Windows 2003 Server. Operationally everything else is fine, except the network icon in the bottom right taskbar has a red X on it, indicating that the network cable is unplugged. I

I have removed the network card from the VM configuration and re-added it (its set to Bridged by the way) and will detect the network card presence, but still give me the unplugged message. I cannot IPConfig /renew successfully as it is considered unplugged.

In the VMWare web console, the network card in the hardware list also has a red X on it and indicates that it is 'disconnected'. I then click the Connect radio button and press OK to no avail.

I can't describe all of the steps that I have attempted (it would take pages) but sufficed to say I have attempted the following:

1. Disabled the wired card on the host machine
2. Disabled the firewall on the host machine
3. Removed the network cards from the VM configuration both in the console and in the guest OS
4. Installed the latest VMWare tools
5. Added 2 network cards to the VM config (guest Windows 2003 server sees 2 unplugged network cards)
6. Added Static Mac Address's to said Interfaces.

I do notice that there are no virtual VMWare adapters in the host machine network configurations (are these relevant with V2.0?).

In the VMWare 'Manage Virtual Networks' tool I am unable to see or set any references directly to the host machine physical network card. This seems to be the most glaring issue, but I could be wrong. When I try to add a new Virtual Adapter, it accepts it as say VMNet1 but nothing happens after that.

Any ideas anyone???

the VM's (5 of them) were running correctly this morning before I Migrated this box from Vmware Server 1.06 to 2.0.1. This is the 4 box that I have upgraded but it is the first to see problems of any nature at all.

They Are the latest NIC drivers on the Vmware servers. On a side note I have 8 2650's and 2 6650's from dell. 3 2650's and 1 6650 are running VMware server 2.0.1 with out issue.

What does the Windows Device Manager reveal ? Does it have any Yellow Coloured Exclamation mark indicating that there is a problem with the NIC ?

I have re-tried rebooting the server 3 times. I am just now coping the Data files to one of the other vmware 2.0.1 Servers to test the process there.

none. on these Boxes or the Hosts. Too much of a performance hit on the virtual machines when they scan. On a side note I have moved the VDMk's to a different machine (VMS06 instead of VMS04) and re-created the server with a "I_copied_it" option. VM is running fine now. I don't really see this as a fix though.

I completely agree with you. This is only a workaround.

Please check the speed and duplex setting at both the Switch as well as at the NIC level.

If its set to Auto-Negotiate, then set the speed and duplex to manual speed (1000) and duplex (full).

Try if this helps.

These settings were forced to the switch when the port was lit up. I am thinking I might Flatten and rebuild the Server for a fresh install of Vmware server.
