STATUS ====== Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem was corrected in the latest Microsoft Exchange Server 5.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces): S E R V P A C K MORE INFORMATION ================ When the maximum inbound connection limit has been reached, the IMS should immediately reject any new inbound connections. Instead, the IMS queues the connection for reverse DNS resolution. This can result in a large queue of connections to be resolved. The maximum inbound connection limit is 30 by default. To set the maximum inbound connection limit in the IMS: - Click Connections. On the Advanced tab, type the maximum inbound connection limit.
