There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)

When you install Exchange 2010 SP2 , you face an error There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)

“$error.Clear();
if (!(get-service MSExchangeADTopology* | where {$_.name -eq “MSExchangeADTopology”}))
{
install-ADTopologyService
}
” was run: “There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)”.
There are no more endpoints available from the endpoint mapper. (Exception from HRESULT: 0x800706D9)

It seems the error is caused while trying to add a firewall rule, indicated by Interop.NetFw.INetFwRules.Add (INetFwRules is the rules collection of the built-in Windows Firewall).

I had a quick check with the firewall settings on the machine and it turned out the Windows Firewall was disabled. I figured that perhaps adding the rules failed because setup couldn’t communicate with the firewall service.

I enabled the Windows Firewall and this time the upgrade process went fine
