MSBTS_HostSetting is Not Found - powershell

Question

Upon building a script to automate the deletion of Host and Host Instances, I run the script below in PowerShell.
PS
C:\WINDOWS\system32>
[System.Management.ManagementObject]$objHostSetting =
([WmiClass]"root/MicrosoftBizTalkServer:MSBTS_HostSetting").Delete()
However, after running the script, it seems that the MSBTS_HostSetting is gone because I was receiving the error below every time I am running it.
PS
C:\WINDOWS\system32>
[System.Management.ManagementObject]$objHostSetting
=[WmiClass]"root/MicrosoftBizTalkServer:MSBTS_HostSetting" Cannot convert value "root/MicrosoftBizTalkServer:MSBTS_HostSetting" to type
"System.Management.ManagementClass". Error: "Not found " At line:1
char:2
+ [System.Management.ManagementObject]$objHostSetting =[WmiClass]"root/MicrosoftB ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [], RuntimeException

I am trying to load the BizTalkOMExplorer but the MSBTS_HostSetting has not returned. Any suggestions or knowledge how can I bring it back.

Answer 1

Just fixed my issue! Below are what I've done.
Open CMD and register the BTSWMIProvider.dll
Example:
Regsvr32.exe “C:\Program Files (x86)\Microsoft BizTalk Server 2013 R2\Bins32\BTSWMIProvider.dll“
Run the following in CMD as well.
mofcomp.exe BTSWMISchema.mof
mofcomp.exe BTSWMISchema.mfl
Restart WMI in services.
This would do the trick! :)

With PowerShell, you can get your HostInstances as:
$hostInstances = Get-WmiObject MSBTS_HostInstance -namespace root\MicrosoftBizTalkServer -ErrorAction Stop
And then you can find which one you want to delete and invoke Delete method:
$hostInstances[0].Delete()
The same with Hosts:
$hosts = Get-WmiObject MSBTS_Host -Namespace root\MicrosoftBizTalkServer -ErrorAction Stop
$hostToDelete = $hosts | where {$_.Name -eq 'HostNameToDelete'}
$hostToDelete.Delete()
