John Howard, Senior Program Manager in the Hyper-V team at Microsoft, shared a sample VBScript you can use how to determine which domain-joined servers are running Hyper-V by using the SCP or "Service Connection Point" information in Active Directory.

NOTE: To use the script, edit the call highlighted “DoQuery". Insert the appropriate domain for your organization. Add multiple lines if you have multiple domains. If you want a list of machine names, uncomment the code-block starting "oRecordSet.MoveFirst" and ending "Loop"

Save the contents as "FindServers.vbs" (or download the text file) and run the following from an elevated command prompt:

 "cscript FindServers.vbs"

On Error Resume Next

Const SCP = "Microsoft Hyper-V"

' Add as many lines as needed for the domains in your org. 

DoQuery "DC=YOURDOMAIN,DC=com", "YOURDOMAIN", SCP

Sub DoQuery(szDomainDN, szDomainShortName, szSCP)

    Set oConnection = CreateObject("ADODB.Connection")

    Set oCommand = CreateObject("ADODB.Command")

    oConnection.Provider = ("ADsDSOObject")

    oConnection.Open "Ads Provider"

    oCommand.ActiveConnection = oConnection

    oCommand.Properties("Page Size") = 99

    oCommand.Properties("Searchscope") = &H2 'ADS_SCOPE_SUBTREE

    oCommand.Properties("Chase Referrals") = &H60 

             'ADS_CHASE_REFERRALS_ALWAYS

    oCommand.CommandText = _

       "select distinguishedName from 'LDAP://" & _

       szDomainDN & "' " & _

       "where objectCategory='serviceConnectionPoint' " & _

       "and cn='" & szSCP & "'"

    Set oRecordSet = oCommand.Execute

    If Err Then

       wscript.echo _

           "ERROR: Unable to find Domain Rooted at: " & _

            szDomainDN

       exit sub

    End If

    If Not oRecordSet.EOF Then

       wscript.echo szDomainShortName & ":" & _

                    oRecordSet.RecordCount

       ' If you want to enumerate the machine names, 

       ' uncomment this block of code

       'oRecordSet.MoveFirst

       'Do Until oRecordSet.EOF

       ' szNodeName = _

       ' oRecordSet.Fields("distinguishedName")

       ' 'Trim "CN=<szSCP>,CN="
