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.
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.
