I have two PC's with Vectorworks 12.0.1b installed, one works fine and the other randomly gets the following error message: "Network Dongle Protection error No recognizable network dongle is connected to the network dongle sever HASP License Manager) VectorWorks will now quit"
The difference in the PC's is that the one that works is a standard Windows XP SP2 build with not much else installed but Vectorwork.
The second PC is a University ZenWorks build, Windows XP SP2, with a whole range of other software, Novel client, Zenworks, Autodesk, Adobe range of products,
Using the HASP ini files I have restricted down the two PC's and license server to use only TCP or UDP and on port 4751, there are no firewalls in the way, and there is only a basic home office switch in the middle.
I have spent quite sometime investigating the problem using the Sysinternals tools, Regmon, Filemon, processmon, TDImon, with not much results.
TDImon monitors TCP/UDP traffic in/out of a workstation, and I can see the workstation communicating on port 4751 to my license server and my license server communicating back no failures.
But if I monitor my PC that works and then stop the License server I can see it sending traffic to the License server but no traffic back and then failures.
From this I would assume the communication between my not working PC and the License server is fine.
Even at the time the error message appears there are no TCP/UDP traffic failures only successes.
Regmonm, Filemon and Processmon don?t really show much at the time of the error, but I assume this is because of the HASP security layer, if simple tools like that could interrogate the HASP communication then it would be easy to crack.
I have compared all services between the working and not working PC and stopped any that were extra and started up any that were disabled - I still receive the dongle error.
I have compared all running process between the working and not working PC and ended task any that were different - still the same dongle error.
The dongle error can appear as soon as I start up the application, or after 1 minute, 5 minutes, or even one time 30 minutes, it seems to be very random most of the time it fails in less than 5 minutes.
I suspect that the HASP communication is fine and working, but that when Vectorworks gets the key back from the license server it is not saving it or activating the application with it.
Any help would be much appreciated, and any information into how the HASP key handshake process works would be very helpful.
