There isn't really anything specific we can do to help you - we don't know exactly what is going on, or what the rest of your setup looks like.But...you mention "network" in your heading, and a quick google says that the StoreJet is USB3, not network connected, so I'd ignore wireless / wired...

There is no way we can answer this because we cannot see the code nor your network. However, SQL server can handle many connections so unless someone wrote really poor code, it should be working fine. We would need a lot more info from you if you want anything more specific.

You cannot use the Local System account for your application. Lcaol System only has permissions to that system, nothing else. If your app is looking at each system to collect data, it'll have to run under and account that has permissions to get to that data on every machine. System and Local...

If it would be possible, it would be a very weak protection. Nobody in clear mind won't store non-ciphered passwords anywhere — they are never needed for authentication.[EDIT]To understand how to store authentication (it that is what your second question is about), learn Assymetric...

If you're in a Windows environment the access privileges should be handled via Active Directory. As SA pointed out, no reason to store passwords or user names in programs.Also another thing. Is the database Access? If not and it's for example SQL Server then you don't need (or to be precise...

You need to host it somewhere over the internet. Right now its hosted on the webserver on the system which is not accessible from the internet. Try some free asp.net hosting sites .. This one is worth giving a try - My favourite one is smarterasp.net[^]

Java is not the best language choice for this type of application, you would be better studying C or C++. You also need a thorough understanding of the API available within the OS that you plan to work with.

While it is good to understand networking by generating your own packets, you don't need to write a program to do that. My advice is to generate packets using Ostinato - the process of generating packets as a user in Ostinato is low level enough for you to understanding the networking packets,...

12 Apr 2013 by jsolutions_uk
If you want a multi client server (who wouldn't?) you shouldn't need to listen on 40 different sockets, but rather a single socket. On recieving a connection, spawn a thread to handle the connection... or a process if you want to go old school :)In fact here's a good example Beginning...
12 Apr 2013 by Manfred Rudolf Bihy
You're trying this the wrong way round. The server should have one socket (IP-adress and port) on which it accepts connections and then it will spawn a separate thread for each client that connects. If you were to do it your way you'd need either 40 IP adresses and listening on one designated...

12 May 2013 by Sergey Alexandrovich Kryukov
I think that using threads with blocking sockets instead of asynchronous API is much better. In most cases, communication is sequential in its nature and the flow of operations is logically independent from other threads. Therefore, using a separate thread for each communication channel (in case...
