Removing CA eTrust 8.x AntiVirus through a script

I had a problem where i needed to remove the AV off our servers on a large scale and found that the manual process for this was quite time consuming.

Because CA sold the antivirus business to TotalDefence, a lot of the documentation disappeared from their website so it took some playing around with how to do it successfully.

The batch file does the following steps:

  1. Stops all eTrust services.
  2. Kills the processes just in case they are lingering

Migrating DHCP from Windows 2003 to Windows 2012 and setting up failover: Part 1

DHCPThe principles of DHCP are simple and Microsoft has not changed its core since before Windows NT days, however its not something you shouldn’t undertake lightly or ill-prepared. Most of your client devices will rely on DHCP to function and failing to migrate seamlessly will only cause disruptions to your business.

This article is to help document how to migrate multiple active DHCP servers to a new DHCP server running on Windows Server 2012. We will finalise the configuration by creating a failover for all scopes to a secondary server. I am writing the to include all the necessary information that I think is required to complete this successfully. Read more »
