How to Troubleshoot Black Hole Router Issues

This article defines the term "black hole" router, describes a method of locating black hole routers, and suggests three ways to avoid the data loss that can occur because of a black hole router.

On a TCP/IP-based wide area network (WAN), communication over some routes may fail if an intermediate network segment has a maximum packet size that is smaller than the maximum packet size of the communicating hosts--and if the router does not send an appropriate Internet Control Message Protocol (ICMP) response to this condition or if a firewall on the path drops such a response. Such a router is sometimes known as a "black hole" router.

You can locate a black hole router by using the Ping utility, which is a standard utility that is installed with the Microsoft Windows TCP/IP protocol. You can then use one of three methods of fixing or working around black hole routers.

When a network router receives a packet that is larger than the size of the Maximum Transmission Unit (MTU) of the next segment of a communications network, and that packet's IP layer "don't fragment" bit is flagged, the router is expected to send an ICMP "destination unreachable" message back to the sending host.

If the router does not send a message, the packet might be dropped, causing a variety of errors that vary with the program that is communicating over the unsuccessful link. (These errors do not occur if a program connects to a computer on a local subnet.) The behaviour may seem intermittent, but closer examination shows that the behaviour can be reproduced, for example, by having a client read a large file that is sent from a remote host.

Troubleshooting Active Directory replication failures that occur because of DNS lookup failures, event ID 2087, or event ID 2088

This article describes an action plan for administrators and for support professionals to follow when domain controllers that are running Microsoft Windows 2000 or Microsoft Windows Server 2003 cannot replicate Active Directory because of DNS lookup failures. Administrators who are troubleshooting replication or other component failures that occur because of a lack of DNS name resolution should follow this action plan.

This article also discusses two new events, event ID 2087 and event ID 2088, that are logged by destination domain controllers that are running Windows Server 2003 with Service Pack 1 (SP1). These events occur when a lack of DNS name resolution prevents the inbound replication of Active Directory directory service partitions. More significantly, in this problem scenario, Windows Server 2003 SP1-based destination domain controllers will use the source domain controller's fully qualified domain name in DNS or the source domain controller's NetBIOS computer name in Windows Internet Name Service (WINS). The goal of the enhancements in Windows Server 2003 is to minimize the effect of DNS client or DNS server configuration errors on Active Directory replication.

n a peer-to-peer workgroup, when you try to connect to the network resources of a computer that is running any of the products listed at the beginning of this article, you may receive one of the following error messages:

Operating system error 71.
No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept.



System error 71 has occurred.
This remote computer has reached its connection limit, you cannot connect at this time.

This problem occurs when a computer reaches the maximum number of host connections that are allowed. In this case, when a NULL session connection is generated in the Microsoft Windows 2000 client, this NULL session connection is counted as one session on the Microsoft Windows XP-based server. Therefore, the error messages occur that are mentioned in this "Symptom" section, even if the number of connections to computers do not exceed the limit.

In addition, when multiple NULL sessions are generated from a single Windows 2000 client computer, the multiple NULL sessions are counted as multiple sessions. However, a NULL session appears as a single session when you run the net session command. In this case, when the RestrictAnonymous registry entry is set, and the NULL session connection is rejected, this symptom still occurs.

How to use Memory Pool Monitor (Poolmon.exe) to troubleshoot kernel mode memory leaks

This article describes how to use the Memory Pool Monitor utility, Poolmon.exe, as a troubleshooting tool to monitor memory tags.

Poolmon displays data that the operating system collects about memory allocations from the system paged and nonpaged kernel pools and about the memory pools used for Terminal Services sessions.
