If you have a box of that sort, that has a switch with some number of Ethernet ports into which you plug machines on your network, and another Ethernet port used If there is an application relying on the packet.dll file you will not be able to delete it. my review here

Q-8: Can I use WinPcap with Borland development tools? Most of the times, the problem is caused by non-standard interactions between the firewall and the network stack of the OS, so there not a lot to do on our side; Note in particular that the WinPcap driver is loaded inside the kernel only when the first capture application opens an adapter after a machine boot. It works also on PPP WAN links, but with some limitations (for example it is not able to capture the LCP and NCP packets).

AirPcap at this time is the only solution for capturing raw 802.11 traffic with WinPcap. these systems have limitations in the NDIS binding process that prevent a protocol driver from working properly on WAN adapters. Double-click or right-click and select "Properties" On the "Driver" tab of the properties page, the current status and "Start" or "Stop" buttons are displayed.
