Checkpoint R75 prevents Wireshark from capturing ALL packets

Hi,

This isn't a question, its an answer to my own question. I had problem capturing packets onsite with Windows 7 64bit, however other PCs from colleagues (XP 32 bit, 7 32bit and 7 64bit) worked fine. I tried everything: - Reinstalling Wireshark (with the NPF set to start on boot) - Trying MS Network Monitor instead - Checking McAffe didn't have any firewall functions - Installing latest Intel network drivers - Checking intel supports promisbious mode - Checking Windows 7 supports promiscious mode

The issue turned out to be Checkpoint Endpoint Security R75 (the VPN client), once uninstalled (and rebooted) it worked first time.
