    View Instant Clones Pool provisioning breaks when using OS Optimization Tool (default Windows 10 template).

    LAANSID Novice

      Hi,

       

      Hope someone can help me out with the following error.

       

      Environment:

      I am working on a VMware Horizon 7.3.2 environment with only one Windows 10 (Enterprise x64 1607) Instant Clone Pool (+/- 20 desktops).

      Like almost everyone, I use the OS Optimization Tool (OSOT) to optimize the golden/master/base image for VDI. The only thing we change is from the defaults is place a check at "disable the first logon experience".

       

      Problem:

      Since november 2017 or something the provisioning process breaks after customizing the cp-template machine.

      Cloning the golden/master/base image is successful, it re configures the cp-template, starts-up, and then it times out after 600 seconds (10 minutes).

      After half a day (error created in evening), when I enable provisioning in the morning it is going pass the timeout and provisioning is successful.

       

      Findings/Troubleshooting:

      My first thoughts were going to DHCP, DNS and AD, but they are working correctly (monitored all the registrations). The itXXXXXX is member of the AD and also gets an IP-address of the right DHCP server and register it in DNS.

      So continued troubleshooting and it works only correctly when when I don't use the "OS Optimization Tool". It never times out at the above step in the process.

       

      Error in log:

      Within the Horizon Connection Server logs I see one line of the error without any root cause to search for: 2018-01-17T13:35:46.020+01:00 DEBUG (0D5C-1278) <WFE-01> [WaitForInternalTemplateAction] Internal Template: vm-4377 customization state returns: error.

       

      Alert in Horizon:

      The error in Horizon View Administrator Console (Desktop Pool) is: After waiting for 600 seconds internal template VM: vm-4377 is still has not finished customization. Giving up!.

       

      Does one of you experience, read or find a solution for this? Within OSOT a lot of customizations take place and it is searching for a needle in a haystack.

      Thank you in advance.
