- Normally dynamips test failed when execution path is define incorrectly, make sure your default path should be C:\Program Files\GNS3\dynamips-wxp.exe. In executable path basically you need to locate the "dynamips-wxp.exe", therefore you can manually browse the file from gns3 installation directory. In vista default installation this may be C:\Program Files (x86)\GNS3\Dynamips\dynamips-wxp.exe , so manually locate "dynamips-wxp.exe".
- Also try to change the default working directory.
- Ensure base port, udp port and base console are selected (7200, 10000, 2000)
- Added the GNS3 and Dynampis Executables to Windows Firewalls exceptions. for window 7 open "Control Panel\All Control Panel Items\Windows Firewall\Allowed Programs" and add these if they are not exist there.
- Otherwise click on Add another program and add dynamips-wxp.exe and gns3.exe.
- In Windows XP, Go to the control panel > windows firewall > exceptions > add program. Add GNS3.exe and Dynamips-wxp.exe. Then go to add port and add UDP Port number 7200. Then OK and Reboot.
