Provisioning Services antivirus exclusions

Citrix wrote an excellent article about the PVS Antivirus exclusions and thought I will share it with you.  In my experience with PVS, this is very crucial step as it will ensure you don’t interrupt the streaming process and/or slow things down.

If you are like me and decide to run the TFTP boot process on separate servers, you can create TFTP HA utilizing the NetScalers, if you decide to go this route which I recommend, you will need to exclude the TFTP directory on the separate TFTP hosts.  You can read about how to HA the PVS  TFTP boot process via the NetScalers from a previous post I wrote, which let me tell you it was no easy task.
