VMWARE Server 1 Guest NIC not working at Gigabit speed with Gigabit host NIC

Posted on 2008-10-23
Last Modified: 2012-05-05
I have a host server with an Intel Gigabit NIC (Intel PRO/1000 GT) and I was wondering how I can get it to work as a Gigabit NIC in my Windows 2003 Server Guest OS.  Currently I can only get a maximum of 5.5 MB.sec transfer rate yet between the host machine and another server on the network with a Gigabit NIC I can get over 50 MB.sec.

Do I need to reinstall the vmtools or have the NIC reinstall itself? This is on a production server so I have not fooled around with uncertain fixes yet.

Please update the host operating system on which VMware Server is installed.
Kindly check the Duplex and Speed setting in the host machine (whether it is in Auto Negotiate Mode or you have manually specified the setting)

Have you installed VMware tools? I believe without the tool, your virtual nic on your guest os is limited to 10mbps.

Yes the VMTools are installed.

I would check traffic shaping on the virtual machine port groups next.

I'm assuming all other vms on this host run fine except for this one.

Please update whether the issue is in VMware Server or VMware ESX.

After much testing and troubleshooting it ended up being a hardware issue.

thanks for your help, in the end it was a hardware problem but your assistance was helpful in isolating it.
