Why do sessions stop assembling on setting CheckTcpSum property to TRUE?
A. The thing is that some network adapters vendors give an opportunity of the checksums calculating and checking at sending and receiving the network packets by network adapters drivers. Windows has information that the driver has such an opportunity that is why it does not check the checksums so to save the processing time. Thus capturing sessions from a local computer you may receive some packets with uncalculated checksums, since local packets capturing occurs prior to sending them to the network adapter driver. In the next version of PSSDK a new property will be added into HNAdapterConfig object, which will warn about the capability of the netcard to calculate and check the network packets checksums.
