ESX Server Virtual Machines Running Windows NT 4.0 Guest Using the vmxnet Virtual Network Adapter Lose Network Connectivity
Details
On ESX Server 2.5.2 patch 1, ESX Server 2.5.1 patch 1, ESX Server 2.1.2 patch 4, and ESX Server 2.0.1 patch 4, virtual machines running a Windows NT 4.0 guest operating system with a vmxnet virtual network adapter lose network connectivity after a short period.
How can I fix networking on my virtual machines?
Solution
To work around this problem, use the vlance network adapter. If doing so is not feasible, download a patched vmxnet driver for Windows NT from www.vmware.com/download/esx/esx2-16515update.html.
