VMware ESX Server 2.5.2 Upgrade Patch 1 (for 2.5.x Systems)
This patch for ESX Server 2.5.x addresses the following issue:
- Loss of network connectivity in virtual machines running Windows NT
4.0 and using the vmxnet virtual network adapter. The virtual network
failure happens a short while after starting the virtual machine. The
problem is fixed in this patch release. See
Base Article 1854. If you cannot install the patch release, you can
work around the problem by using a vlance virtual network adapter
instead of a vmxnet virtual adapter in your virtual machine.
There are separate patches for ESX Server 2.1.2 and 2.0.1 available as the
