Uhm, do you refer do WinPcap 3 beta 1 released in February 2003???

So your app is compiled against the 3.1 devpack, and it crashes on every
machine where WinPcap 3.1 is installed?

Uhm, I seriously doubt so. There are no breaking changes in the API that
would cause such problems (and in any case you cannot have such issues if
you use devpack 3.1 *with* winpcap 3.1). Which API are you using? pcap or
Are you able to debug the issue (or at least have a trace) on the faulting
machines, and understand exactly which function is crashing?

I double checked on the server, and they are the proper ones.
Have a nice day
