SMS Network Monitor 1.2 Does Not Work with Network Monitor Agent 2.0

When you try to run SMS Network Monitor 1.2 in Windows 2000, the program may be unable to find a network driver to begin the capture. This behavior can occur when Network Monitor Agent 2.0 is installed instead of Network Monitor Agent 1.2.

You may receive an error message stating that the Nal.dll file is missing or cannot be found.

Network Monitor Agent 1.2 must be installed for Network Monitor 1.2 to work. The driver for Network Monitor Agent 2.0 may not work with Network Monitor 1.2.

To use Network Monitor 1.2, copy the Nal.dll file from the Windows NT 4.0 CD-ROM to the folder in which Network Monitor is installed. This 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.
