ISA2004中出现被拒绝的连接，但规则为空，这是什么原因？该如何解决啊？

被拒绝但规则为空，这个问题微软有的答复是：

Logs Show Empty Rules Deny Requests
Problem: In the Rule field, the log indicates "-" (empty) as the rule denying the request.

Cause: The Rule field is marked empty when ISA Server denies the connection for any reason other than a firewall policy rule. The Result Code field indicates the reason. For example, the rule may have been denied for the following reasons:

• No network relationship was defined between the source and destination.

• ISA Server considered the traffic spoofed.

• The request is from a client with too many open connections.
