The RPC server is unavailable. (Exception:0x80076BA)

[CitricAcid]

I am running a Windows Small Business Server 2003 SP2, another server with ISA Server 2004 among several desktops.

When I try to run a script I get the following error in all the computers in my network :

"The RPC server is unavailable. (Exception:0x80076BA)"

The script just works if I run it locally in each computer. How do I fix it?

This problem occurs because of a mismatch in the computer name and the name that the RPC service expects. This mismatch may occur if the computer name is changed by using one of the following methods:

• The Microsoft System Preparation (Sysprep) tool was used to create the Windows XP image that you used to start the computer.
• You change the computer name during the Windows XP Out of Box Experience.
• One or more of the following conditions are true:
  
  • You disconnect the network cable during the Windows XP Out of Box Experience.
  • You do not restart the computer after the Windows XP Out of Box Experience has completed.
  • You open Disk Management.

This is most likely caused by not having enough ephemeral ports available. By default, Windows maintains TCP/IP connections for up to 4 minutes.

Open up the registry editor and add the following key and value:

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort=65000

It may be a DNS problem, where the ISA can't find active directory. (It should be using the AD DNS for name resolution on its network cards.)
