When upgrading Wireshark (a Network Protocol Analyzer, formerly known as Ethereal) and WinPcap, a message appeared:
System Information Operating system detected on registry: Windows vista - x86 True operating system (kernel.dll): Windows Vista - x86 npptools.dll present on the system: false netnm.inf present on the system: false nmnt.sys present on the system: false
This message is normal.
npptools.dll, netnm.inf and nmnt.sys are components of Microsoft’s Network Monitor (netmon) utility. Netmon is a network traffic capture and protocol analysis utility, similar to Wireshark.
