⚠️ Limitations

• Only available for Windows operating systems.

• Lacked advanced stealth scanning techniques found in modern tools.

• No active development of the 2003 version; newer versions are recommended for current systems.

📦 Modern Alternatives

While NetScanTools Pro is still available today in modern versions, if you're looking for current tools with similar or extended functionality, consider:

• Nmap/Zenmap

• Wireshark

• Advanced IP Scanner

• Angry IP Scanner

• Netcat

NetScanTools Pro 2003 was a comprehensive suite for its time, offering a range of powerful utilities that made it invaluable to network administrators and security testers. It provided a user-friendly GUI and broad diagnostic capabilities, making it easier for users to understand the underlying behavior of network systems and services.
