Comments on: Enabling Enhanced VMXNet http://blog.scottlowe.org/2008/12/15/enabling-enhanced-vmxnet/ The weblog of an IT pro specializing in virtualization, storage, and servers Wed, 08 Feb 2012 17:13:47 +0000 hourly 1 http://wordpress.org/?v= By: John http://blog.scottlowe.org/2008/12/15/enabling-enhanced-vmxnet/comment-page-1/#comment-43926 John Fri, 20 Mar 2009 22:00:17 +0000 http://blog.scottlowe.org/2008/12/15/enabling-enhanced-vmxnet/#comment-43926 Another caveat: I also had the same problem with network connections being created, as well as: 1) the 'old' AMD NIC not being removed and requiring command-line configuration of Device Manager to remove the old NIC (later realized this could have been avoided by removing the NIC before taking it out of inventory but then I would not have been able to log on to it again); 2) creation of addtional IP addresses for the server(s) within DNS, causing all kinds of unexpected problems. Solution: This method can be used but you must plan for several extra steps and time for making sure the old NIC is removed and that your DNS doesn't get mucked about with, you have to clean out any DNS entries that do not belong, also do this multiple times if you have more than 1 DNS server in your LAN.

I know this is obvious to someone like you, but a note should be added just to be safe. Also for some reason after adding the vmxnet NIC I had problems with Outlook 2003 the next day.

This should be rectified as of the latest shipping ESX3.5 updates. Advanced should be an option on all guest OSes where it would work, including Windows Server 2003 Standard.

Enhanced VMXNet adapter is a vCenter selectable option for 32-bit Windows Server 2003 Enterprise Edition along with 64-bit. I have used it successfully to allow jumbo frames to 32-bit Windows 2003 Enterprise Edition VM’s.
