FIX: There is a long delay when you try to view another policy rule in ISA Server 2006 or in Forefront TMG 2010 if the array contains multiple ISA servers or Forefront TMG servers

Consider the following scenario:

• You install Microsoft Internet Security and Acceleration (ISA) Server 2006 or Microsoft Forefront Threat Management Gateway (TMG) 2010 on multiple members of an array.
• You run the ISA Server Management console or the the Forefront TMG Management console to view a policy rule for ISA Server or for Forefront TMG 2010.
• You try to view another policy rule.

In this scenario, the operation may take a long time.

Note If the array has more than five members, this issue usually occurs.

Note The supported fix forForefront TMG 2010 is included in Forefront TMG 2010 Service Pack 1 (SP1).

This issue occurs because the authentication for a remote procedure call (RPC) call from the management console to each array member is slow.
