Hello Experts,

I would like to set my Network Speed to 100mbps from 1Gbps (I see this from BGInfo) however, I do not see the option in the network card properties. (I see only 3 options: MTU, NetworkAddress and TsoEnable)

How can I change this setting for VMWare Workstation for Windows 2003 Server image?

Thank you

Thank you both.

However, I use VMWare Workstation, the link explains 'How to' with ESX server. The info does not apply VMware Workstation (?)

Well, your KBs are actually for ESX, and the poster is wanting to know how to change the speed/duplex within a VMware Workstation setup. Open up your VMware Network Editor (Start -> Pgms -> Vmware) and assign a vmnet# as 'bridged' and select a specific host adapter.  I believe what you can do is assign your Workstation VM (W2K3 VM) to that vment# in its Edit Settings in Workstation, then configure your host adapter's speed/duplex by going into the Ntwk Connetion Properties and select to 'Configure' your adapter. On the Advanced tab is where you can select the appropriate speed/duplex.

Hope that helps.

Hi Coolsport00,

I already have what you described: a bridged connection to a specific Network card on my PC. This Card is set to 100 mbps Full Duplex - however, the images show 1GBps. Now is it normal?

Is there an "ethernet0" parameter I can set to use this configuration?

Sorry, I have 3 Windows 2003 Server vmware images I have been working on. Their network card cannot be modified and show 1gbps

Sorry for the delay :)

Ah, I see...so, W2K3 VMs :)  Ok...well, Workstation uses the Intel Pro/1000MT adapter for its VMs (see pg. 286 of the Guide here: http://www.vmware.com/pdf/ws71_manual.pdf), so yes...you will see 1Gb. It doesn't actually use that speed...it uses whatever the lowest throughput is in the network connection of your LAN, between the VM NIC...host NIC....switch, etc.; but in this case, your host NIC. Keep in mind a VM doesn't have an actual NIC per sè, it uses the phys NIC from the host.

Hope that helps.
