when the network profile of a Windows PC is set to public, there are firewall restrictions enabled which could prevent accessing the Computer from network. For example Windows Remoting.

ESXi offers some extented methods to capture network packets. Here are some examples.
First of all logon to your ESXi host by ssh.
To capture all traffic on a vmkernel interface use tcpdump-uw.
List all vmkernel interfaces
~ # esxcfg-vmknic -l
Issue: You have Windows Server 2012, 2012R2, Windows 8 or Windows 8.1 running on ESXi or VMware Workstation and the network connection is interrupted frequently.
Also EventID 27 and 32 with source e1iexpress are often logged to the Windows EventLog.
VirtualBox offers a very powerful command inferface: vboxmanage. With vboxmanage you can create new virtual machine, add and modify harddisk and much more. All the things you could do in the GUI, and a lot more are also possible at command line. In this post I will create, modify, control and delete a complete virtual machine.
At the bottom of the post the whole script can be downloaded.
I used a debian linux system for my tests. To install the latest VirtualBox version use the following commands:
echo "deb http://download.virtualbox.org/virtualbox/debian wheezy contrib non-free" >> /etc/apt/sources.list
# Add Oracle Keyring
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | apt-key add -
# Update repositories
# Install latest virtualbox version
apt-get -y install virtualbox-4.3
# Installing the Extentionpack for USB2 and RDP support
VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.6-91406.vbox-extpack
