SYMPTOMS

Using the TRACERT command with Microsoft TCP/IP-32 does not return the correct IP name (Inverse Mapping). For example, running

   tracert 130.20.7.77

should result with the following output:

   plato.lc.microsoft.com.20.130.IN-ADDR.ARPA

CAUSE

TCP/IP-32 does not send a properly formatted query to a Domain Name Server (DNS).

STATUS

Microsoft has confirmed this to be a problem in the Microsoft TCP/IP-32 protocol. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
