Reassigning Personal WVD

iggyemu 

Did you tried WVD Spring 2020 , anyone know in WVD spring 2020 the same feature is introduced or not , currently we are also facing same issue , In personal pool once user is assigned to session host we could not able to assign the instance some once in cause of existing user resigned the organization.

thanks in advance.

iggyemu  I had a similar ask

https://docs.microsoft.com/en-us/powershell/module/windowsvirtualdesktop/remove-rdssessionhost

From above powershell doco it states that

When running this command to remove a session host from a persistent host pool, the user assignment is also removed. This is the only way to re-assign a user to a new session host in a persistent host pool.

So the best I was able to achieve was

Remove-RdsSessionHost -TenantName TenantXYZ -HostPoolName PoolABC -Name SessionHostToBeRefreshed

Generate a new token for the session pool via

 New-RdsRegistrationInfo -TenantName TenantXYZ -HostPoolName PoolABC -ExpirationHours 1

 (Export-RdsRegistrationInfo -TenantName TenantXYZ -HostPoolName PoolABC ).Token

Log onto that machine and remove the "Remote Desktop Services Infrastructure Agent" - if there are multiple versions make sure to remove every single one.

The reinstall it (there should be a copy under C:\Program Files\Microsoft RDInfra\Microsoft.RDInfra.RDAgent.Installer-x64.msi)

And when prompted use the token that you generated earlier.

It will take about 5mins for the session host to rejoin.

I would very much prefer a powershell command that can remove assignment rather than uninstalling an agent!

iggyemu I'm experiencing the same issue. Even by removing some users, it will not replace them with the new one I added. Any one has any trick for not having to add a new VM to the pool?

iggyemu That's a very nice question!
