DOCUMENT:Q155758 08-AUG-2001 [winnt] TITLE :IP Received Header Error Count May Be High PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.5,3.51,4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51, 4.0 - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- The "netstat -s" command can be used to view various TCP/IP protocol statistics. Windows NT systems that are running on a TCP/IP network with more than one logical subnet per physical network may display a large number of IP Received Header Errors, as shown below: IP Statistics Packets Received = 84167 Received Header Errors = 10395 <------- Received Address Errors = 94 Datagrams Forwarded = 0 Unknown Protocols Received = 0 Received Packets Discarded = 0 Received Packets Delivered = 73678 Output Requests = 2016 Routing Discards = 0 Discarded Output Packets = 0 Output Packet No Route = 0 Reassembly Required = 0 Reassembly Successful = 0 Reassembly Failures = 0 Datagrams Successfully Fragmented = 0 Datagrams Failing Fragmentation = 0 Fragments Created = 0 MORE INFORMATION ================ When an IP datagram is received as a broadcast at the link level, it is passed up to IP to process. IP performs a check to see if the datagram is a valid IP broadcast for a subnet that the computer is configured on. If the datagram is not a valid subnet broadcast, it is discarded, and the "IP Received Header Errors" count is incremented. This is a harmless error, but a request has been logged to eliminate this behavior in future versions of Windows NT.
