DOCUMENT:Q152643 13-FEB-2002 [sms] TITLE :Netmon Does Not Capture Outbound Frames PRODUCT :Microsoft Systems Management Server PROD/VER::1.2 OPER/SYS: KEYWORDS:smsnetmon kbNetworkMon ====================================================================== 1.20 WINDOWS kbnetwork ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Systems Management Server version 1.2 ------------------------------------------------------------------------------- SUMMARY ======= When capturing network traffic "to and from" the local computer, network Monitor captures and displays only one-way traffic (traffic to the computer). Network Monitor running on systems with network interface cards (NICs) that use monolithic Ndis 4.0 drivers may exhibit this symptom. MORE INFORMATION ================ LocalOnly is a new bit that Ndis4.0 supports. It gives Network Monitor the ability to acquire all the network traffic that is going to and from your computer without going into Promiscuous Mode, which is very expensive. Some cards, which are monolithic (non-miniport) or are miniport but implement their own loopback, indicate that they handle the LocalOnly bit, but actually they do not. WORKAROUND ========== To correct this problem a registry entry needs to be added. WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk. 1. Run the Registry Editor. 2. From the HKEY_LOCAL_MACHINE subtree, find the key: \SYSTEM\CurrentControlSet\Services\bh\Parameters 3. On Edit menu, choose Add Key: Key Name: ForcePmode Class: 4. On the Edit menu, choose Add Value. 5. Add the following: Value Name: EPRO1 The value should be the same as the name in the \SYSTEM\CurrentControlSet\Services\bh\Linkage key, under the Bind Value with the leading "\Device\" stripped off. There are multiple cards on the same line, space delimited. Data Type: REG_DWORD Data: 1 6. Choose OK and quit Registry Editor. 7. Shut down and restart Windows NT. Note: This does NOT effect Netmon counters within Perfmon because pmode willbe used.
