Symptoms Data collection for a Monitoring Plan (Managed Object in the versions below 9.0) for auditing Windows Server completed with the following error:
"There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)".

 

Cause Incorrect RpcProtocol settings on your DNS Server. 
Resolution To resolve this issue, enable the TCP/IP protocol. You can do it using Registry Editor or Windows PowerShell. 

To enable the TCP/IP protocol using Registry Editor:
  1. On the audited Windows Server, navigate to Start -> Run and type "regedit".
  2. In the Registry Editor snap-in, navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters.
  1. Edit the RpcProtocol registry key according to the regulations below.
    • The value of this entry is a bitmap.
    • You can set multiple bits by adding the bits together and setting the value of this entry to that sum:
BitMeaning
0x0No protocols (disables RPC for DNS)
0x1 (001 binary)TCP/IP
0x2 (010 binary)Named pipes
0x4 (100 binary)LPC
0xFFFFFFFFAll protocols
Note: When completed, restart the DNS Server service.
 

 To enable the TCP/IP protocol using Windows PowerShell:
  1. On the audited Windows Server, navigate to Start -> All Apps -> Windows PowerShell and run it as an Administrator.
  2. Execute the following command:

$Server = "SERVERNAME"

$Setting = "RpcProtocol"

$Value = ""

$SettingsObject = Get-DnsServerSetting -ComputerName $Server -All

$SettingsObject.$Setting = $Value

Set-DnsServerSetting $SettingsObject -ComputerName $Server

Where $Server is your DNS Server name and $Value is the RcpProtocol registry key value. Specify the value according to the regulations below.  

  • The value of this entry is a bitmap.
  • You can set multiple bits by adding the bits together and setting the value of this entry to that sum:
BitMeaning
0x0No protocols (disables RPC for DNS)
0x1 (001 binary)TCP/IP
0x2 (010 binary)Named pipes
0x4 (100 binary)LPC
0xFFFFFFFFAll protocols
Note: When completed, restart the DNS Server service.
