    Is this from a VM of XP? It may have a program in there that wants to connect to some external service.

    Welcome to Windows 8 Forums, if you can give us a few more details - Is this happening in Windows XP running as a Virtual Machine in 8? This may be normal behaviour. If it is just XP, well we can try to help out with that, but I think there is a Windows XP Forum linked to these sets of forums.

    So, you have a windows 8 machine and a windows XP machine and the XP is sending this cack into your gateway? Are these the Router logs you have posted here, cos I don't understand what they are relevant to. How often do these req's get sent? If it is like hundreds every minute, I;d check for Viruses.

    Basically, those are "Bad Packets" being sent to what machine is at 192.168.1.54 - An address like this is ALWAYS a Local Address on your LAN. - So if you are sharing your Windows Media Player playlist/library, that may be doing it, Or, it may be iTunes sharing. Shut all that off and see if it vanishes.

    HI

    I have linux system as a gateway and I have sent a log of that linux system. Request goes to the gateway some time 500 or more than that. I have tried the scan with AVG antivirus also but dont found anyting like virus.

    There might be issue due to that windows folder sharing but I can not stop that because it required. I want to know the root cause of it and want to clean that or remove the same which is generating this unnecessarily requests.

    It is some sharing thing - But I think this is normal operation, there are always bad packets. If you shut that off in the log, tell it not to show the bad packets? Can you do that?

    I don't see anything to worry about, no programs are targeted, it's just a list of dropped packets. Disconnect the XP system from the Server and see if it still lists the drops.

    Hi
    When you see at log then its blocking the unnecessary request from that pc that is ok but actuall problem is when sending that request to gateway in bulk at that time other genuine request may have to suffer or gateway response very slow due to high traffic of unnecessary request sent by netbois-ssn.

    Does your network seem degraded, how is the response time from computer to computer? Are you running any programs on the server which are streamed over to the satellite stations, and if so, are they working right?
