When you attempt to run SMS Network Monitor 1.2 on Windows 2000, it may not find the network driver to begin the capture.

This behavior will occur if Network Monitor Agent 2.0 is installed, instead of Network Monitor Agent 1.2. Network Monitor Agent 1.2 must be installed for Network Monitor 1.2 to work.

NOTE You may receive an error about Nal.dll.

To workaround this problem, copy the Nal.dll file from the Windows NT 4.0 CD-ROM to the folder in which Network Monitor is installed.

NOTE: The workaround allows you to run Network Monitor, but you can only open and edit capture files. You cannot capture packets or transmit packets on the wire.
