Can't create DEDICATED pool - deleteOrRefreshMachineAfterLogoff exception

Error when calling new-hvpool:

Exception calling "Desktop_Create" with "2" argument(s): "ExceptionType : VMware.Hv.InvalidArgument ErrorMessage : deleteOrRefreshMachineAfterLogoff can only be set for floating user assignment ParameterName : desktopSettings.logoffSettings.deleteOrRefreshMachineAfterLogoff" At C:\Scripts\modules\VMware.Hv.Helper\VMware.HV.Helper.psm1:4905 char:7

  • CategoryInfo : NotSpecified: (:) [], MethodInvocationException

This happens whether or not I specify this value "deleteOrRefreshMachineAfterLogoff". If I switch the a FLOATING pool type, it works, but I need it working on dedicated.

I had in these days the same issue. I temporarly solved by editing VMware.Hv.Helper.psm1

Replace from Line 4826 with (to check i InstantPool is DEDICATED):

$desktopLogoffSettings = $desktopSettingsService.getDesktopLogoffSettingsHelper()
        if ($InstantClone) {
            $powerPolicy = "ALWAYS_POWERED_ON"
        }

        if ($InstantClone -and ($desktopUserAssignment.UserAssignment -ne "DEDICATED")) {
            $deleteOrRefreshMachineAfterLogoff = "DELETE"
        }
        $desktopUserAssignment

        $desktopLogoffSettings.setPowerPolicy($powerPolicy)
        $desktopLogoffSettings.setAutomaticLogoffPolicy($automaticLogoffPolicy)
        $desktopLogoffSettings.setAutomaticLogoffMinutes($automaticLogoffMinutes)
        $desktopLogoffSettings.setAllowUsersToResetMachines($allowUsersToResetMachines)
        $desktopLogoffSettings.setAllowMultipleSessionsPerUser($allowMultipleSessionsPerUser)
        if (($desktopUserAssignment.UserAssignment -ne "DEDICATED")) { $desktopLogoffSettings.setDeleteOrRefreshMachineAfterLogoff($deleteOrRefreshMachineAfterLogoff) }

This appears to still be an issue. I get the same error as @mattivoxy I haven't looked at the workaround provided by @rpaloni as this was 2 1/2 years ago and line 4826 might not be where it was!

Hi @gerguk. The last version of Vmware.HV.Helper Module seems was changed from the last time I download it. A changed was introduced to fix the problem but introduce a possible new bug.

$deleteOrRefreshMachineAfterLogoff is set as default to "NEVER" at line 3877 this parameter can be set only for Instant Clone Pool with Dedicated User Assignment

so...

In the actual version of the code you must search the lines 4953 - 4956

if ($InstantClone) {
            $deleteOrRefreshMachineAfterLogoff = "DELETE"
            $powerPolicy = "ALWAYS_POWERED_ON"
        }

Replace them with

if ($InstantClone) {
            $powerPolicy = "ALWAYS_POWERED_ON"
        }

Replace Line 4962: $desktopLogoffSettings.setDeleteOrRefreshMachineAfterLogoff($deleteOrRefreshMachineAfterLogoff)

with

if ($desktopUserAssignment.UserAssignment -eq "FLOATING ") {
$deleteOrRefreshMachineAfterLogoff = "NEVER"
}

$desktopLogoffSettings.setDeleteOrRefreshMachineAfterLogoff($deleteOrRefreshMachineAfterLogoff)

So... when Assignment is FLOATING the only value acceptable "NEVER" will set otherwise the value passed is used.

Hi @rpaloni,

I just wanted to thank you for taking the time to provide such accurate info.

I finally got around to modifying the VMware.HV.Helper.psm1 according to your instructions and am now able to create my Dedicated pools without any issues :-) The change hasn't had any impact on the creation of my Floating pools either

Many thanks, Greg
