RDP error Local Security Authority cannot be contacted

The error:

Remote Desktop Connection: An authentication error has occurred.
The Local Security Authority cannot be contacted
Remote Computer: hostname or ip

The issue:

Seems to happen more on 2012 server but if you have Network Level Authentication enabled it will not prompt you for a GUI change password option if you have change password at next logon selected. This error could happen for other reasons as well

One of the possible fixes:

  1. uncheck change password at next logon if its selected
  2. use a different tool to change your password at first logon

How to connect VI Client 2.5 to VMware Server 2.0

With the new VMware Server 2.0 Beta, if you have installed it the web interface is not the best yet for some real use and if you are using Windows 2008 as the host the 1.0.4 will not install nice. But there is a better way to use this install and get all the goodies that come with Virtual Infrastructure products from VMware.

  1. You will need to install the Virtual Infrastructure Client (VI Client) 2.5.
  2. You will need to have your ports open if you have your firewall up the defaults it takes are 8333 (SSL) 8222 (normal)
  3. On the VI Client for server put in https://<servername&gt;:8333 or http://<servername&gt;:8222 or what ever ports you choose at install.
  4. Then add your Admin account to the host for Username and Password


My setup:

Dell PowerEdge 1800
Host: Windows 2008 64bit Enterprise
2 CPU 3.6GHz
Ram: 6GB
