Provisioning Services (PVS) and Daylight-Saving Time

With daylight-saving time beginning at week’s end (March 8 at 2am), we wanted to provide an overview of the issues that can occur with PVS delivered desktops and XenApp servers.

Some of the issues that occur as a result of the time change are:

  • Time not showing correctly in the Desktop or XenApp server,
  • Desktop failure to register with DDCs,
  • User inability to log on due to domain trust relationship issues caused by the VM/Domain time difference.

The Fix:

  1. Open up your PVS delivered image(s) in read/write mode after the time change has occurred on Sunday.
  2. Run w32tm /resync /nowait” at the command prompt.
  3. Set the image(s) back to read only, following your normal image preparation procedures.

Remember, you must reboot all PVS delivered desktops and servers after you make the above changes to ensure they receive the updated version.

Being proactive will help ensure a smooth Monday morning for all of your users!

Notable Citrix Updates

A couple of weeks back I was able to attend the 2015 Citrix Summit in Las Vegas. The event was a great resource – with sales education, technical deep dives, and an array of new programs. One great bonus was the fact that it was held in January, so I didn’t have to suffer the 110°+ heat of a Las Vegas summer.

There are three releases I want to make special note of – these are releases we have had success with, along with great client feedback. So without further ado, here are my top three notable Citrix updates from the Summit:

  1. XenApp and XenDesktop 7.6 updates: There have been changes in graphic engines, with H.264 becoming the new industry standard. With the release of the 7.6 updates, Citrix is moving in that direction as well.

  1. PVS Cache in RAM, with overflow to Hard Disk (HD): This is a great new feature on PVS, because you can eliminate the need for expansive storage. We have clients currently using this feature, and they can’t tell the difference between 3PAR SATA Hard Drives and Whiptail SSD.

  1. GPU into XA/XD: We have successfully deployed AutoCAD for some of our clients via XenApp, and so far the feedback has been great. One client said, “The performance is as good as if it were locally installed”.
