Network Monitor Setup Doesn't Find Previous Version Installation

• Microsoft Systems Management Server, version 1.2
• Microsoft Windows NT Server, version 4.0

SYMPTOMS

Two menu options for Network Monitor are placed on the Start menu, one in the Administrative Tools group, and one in the Network Analysis Tools group. Depending on which icon you use to start Network Monitor, the Network Monitor program may behave differently or erratically, or it may function with limited abilities (like not being able to capture all network traffic).

CAUSE

The Windows NT Server 4.0 Network Monitor is installed in the <System root>\System32\Netmon directory. By default, the Systems Management Server Network Monitor installation location is C:\Nm (or x:\Sms\netmon if you are installing Network Monitor onto a Systems Management Server site server). If both versions of Network Monitor are installed, you will observe different results in Network Monitor, depending on which Netmon.exe executable file you ran.

WORKAROUND

If the Windows NT 4.0 "Network Monitor Tools and Agent" is installed in the Winnt\System32\Netmon directory before you install Network Monitor from the Systems Management Server compact disc, specify the <System root>\System32\Netmon directory as the installation location during the Systems Management Server Network Monitor installation. However, note that two menu options for Network Monitor are placed on the Start menu, one in the Administrative Tools group, and the other in the Network Analysis Tools group. Both of these icons start the same version of Network Monitor, and you can remove one of them by changing the Taskbar properties.

If the Windows NT Server 4.0 Network Monitor is installed and the Systems Management Server Network Monitor is installed into a directory other than the <System root>\System32\Netmon directory, two menu options for Network Monitor are placed on the Start menu, one in the Administrative Tools group, and one in the Network Analysis Tools group. Each of these icons runs a different version of the program.

To remove the Windows NT Server version of Network Monitor, perform the following steps:

1. On the Start menu, point to Settings and click Control Panel. Double- click the Services icon.

2. Select Network Monitor Tools and Agent, and click Remove.

3. Click Add, and select "Network Monitor Agent."

4. Shut down the computer and restart it.

STATUS

Microsoft has confirmed this to be a problem in Systems Management Server version 1.2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
