Why is the port udp 137 used during a remote desktop session?

I am currently seeing a lot of messages on my firewall indicating port 137 udp is blocked.  I think that when I use remote desktop to a remote system, which attempts to connect to me via the udp port 137 remote systems.  If this is true, why?  This is necessary or if I can change this behavior?

Hello

UDP 137 is used by NetBIOS in Windows 7 file sharing.

According to what you are doing when you use Remote Desktop on your network, it can call the UDP137.

If it does not interfere with something functional you need to do, leave him alone. The Job firewall is to block aspects of network traffic. You don't have to feel 'sorry' to him do his job.

  • Some icons on the start menu are missing after a remote desktop session in Windows 7

    I use Win7 Pro SP1 and whenever I come back to my office after finishing a session desktop connection to my computer remotely, I noticed several of the icons in the all programs from the Start Menu section changed to default page icons. If I try to open any programs that are pinned to the start itself, it will indicate that the program cannot be found. Notepad and Calculator in particular to keep more victims of this problem.

    I also noticed that the audio controller is disabled until I restart.

    I found a batch file that will rebuild the icon cache, but this very annoying to have to keep doing it because I have to remote into my computer almost every morning for the daily scrum meetings we hold in a conference room.

    Does anyone know a permanent fix?

  • IR hotsync problem: "because the port is in use by another application."

    I finally got my system operation.  Sony Clie TJ - 25 pda, Palm Desktop 4.1, Windows 7 64 bit.  Very delicate balance.  I failed to install the new software released by aceeca.  I finally got it by infrared hotsync.  Several times.

    Now, today, I get the message on the Clie: "could not start the hotsync operation because the port is in use by another application."

    I saw this thread and in fact ensure that the transfer of images using a digital camera box is unchecked.  It still does not.  The icon hotsync in the lower right part of the screen, when I check that IR is checked, nothing else is.  It still does not.

    Thoughts?  Ideas?  Suggestions?

    Cidercat I had this happen to me with bluetooth hotsync before. I listen to radio, transfer files and surf the web with bluetooth. I could solve the problem by turning off the bluetooth, then turn it back on. Sometimes a warm reboot might also work. I came across a free application for the Palm tree named NetworkDown. It closes completely all active sessions down. You type right on the icon to run it. It works on my TX.

  • Remote Desktop sessions fail with the error of data encryption

    All my remote desktop sessions attempts fail with an error of bull data encryption *. It seems that half of the world has this error and no one can provide an answer. Before binding you to an answer without value, it is all my clients servers with Windows Server 2003-2011 everything, cannot RDP to any of them.

    Most suggested answers a problem of router or server specific problem or suggest disabling large unloading on the network card.  Well, this problem hooked 30 + servers I've tried lately.  I tried with unloading defined on deactivate and activate.  I tried ethernet and wifi.  I tried to do different internet connect, work, home to various customer sites.

    In other words, I can no longer use RDP to connect to servers on ANY connection.  It simply doesn't work anymore.

    I run Windows 7 32 bit and this couple suddenly some days ago.  Before you start, no virus, no updated drivers... blah blah blah.

    The first day, he started, he wouldn't let me RDP via VPN but if I went through the external IP (mapped ports).  Then, it only works if I was on ethernet, not the wireless.  Then he just decided it wouldn't work at all.  Today, that I even tried to get back into the work remotely via RWW and the RDP ActiveX... did not work.  Tried both servers a SBS 2003 to 2008.  Nope.

    XP has a ten years more of life.  Win7 has done roughly three years, now it starts to fall apart.

    If you can fix this before moving on to Windows 8, and without having to wipe my whole PC, it would be much appreciated.

  • Start the host lock screen remote desktop session

    Is it possible to call the lock of a host machine screen remote desktop without interfering with any active session on this host?

    The host machine might have been locked by someone who just walked away from him or the host computer can be used remotely by its regular users.

    But despite this, I would use it to run a remote session to my regular machine.

  • Losing keyboard focus when the remote desktop session

    Hello

    I have several computers Win7 it remote to the server of a hosting company. Our users will register in the servers of the hosting via remote desktop. The question that arises is that the keyboard stops working after a locking of the user, the computer, then returns after a short period of time to continue working. The remote desktop session will remain functional when the computer is locked. After unlocking the computer, the keyboard does not work in the remote session. The mouse is not affected by this and minimizing the session, the keyboard works fine on the local session. Sometimes, you need to restore down and then restore back or minimize the RDP session several times to get the keyboard works within the remote session. A few times, close the RDP session will cause the keyboard work again. Someone at - he lived it and have a resolution of this problem? This issue seems to occur more frequently and we have already created on the remote server user profiles, but nothing helped. Thank you for your help.

  • Issues of access to the port noticed when using wireshark

    1. I noticed CDP on wearing my workstation, I could see how this could be useful in using a sniffer to find out which port on a switch, you are connected to. I discovered running on this port without activating cdp avoid advertisements of cdp on port. Most of you turned it off or they leave?  If so is it a company policy to do?

    2. the next strange package race was spanning tree (BPDU?) packets, I saw.  I thought that this is coelio why would you see protocols spanning tree on an access port?  I used the command spanning tree bpudguard suggests that would prevent me from receiving bpdus on an access port.  This did not work, what order you we just to not receive bpdu?

    3. the last one is the one that I find it extremely odd that I receive eigrp Hello of my main switch this switch of access level. The eigrp should just broadcast to other switches running eigrp?

    Hello

    1, it depends. If you have Cisco phones, you have cdp enabled on the interfaces. If you don't use phones, you can disable cdp on the interfaces.

    2, Spanning-tree is a loop prevention mechanism. you want to use the tree covering all the interfaces where a loop can occur. You can introduce loops on the access port if you connect a switch on that port. A switch will always send packets bpdus on access ports unless you specifically configure the switch does not to do this. Spanning tree bpduguard is used to protect a port of bpdu packets. If a bpdu is received on a port with bpdu guard enabled, the port closes because it is an invalid configuration. BPDU guard does not filter packets bpdus on a port. If you want to filter packets bpdu on an interface, you use spanning tree bpdufilter. spanning tree bpdufilter stop bpdu packets sent on an interface.

    3, Hello Eigrp packet are sent on all interfaces enabled for eigrp. To prevent the eigrp packets out all interfaces running eigrp, use the passive-interface command in eigrp configuration.

    Thank you

  • On the issue of the port already in use and multiply the application instance?

    I use the message connection to receive sms. When I restart the application, I found the already used port exception. I've been through many posts and believe that BB allows a UNIQUE APPLICATION connecting the port of sms at a time. But the port of sms I know certainly is used only by my candidacy, is somehow wrong to create a second instance of application trying to access this port?

    This question confused me a lot of time, to appreciate someone give me a help.

    This problem has been resolved.

    The two possible solutions for this problem:

    1 re - save the connection string for registery push in the start method. but avoid registering a new when enforcement is woken up by sms push, otherwise it won't get the message.

    public void startApp()
    {
     String[] list = PushRegistry.listConnections( true );
                boolean isByPush = (list != null && list.length > 0) ? true : false;
                if(!isByPush)
                {
                    PushRegistry.unregisterConnection( connString );
                    PushRegistry.registerConnection( connString,Test.class.getName(), "*" );
                }
    
                bbReceiveSmsThread = new BBReceivingSmsThread(connString);
                bbReceiveSmsThread.start();        
    
    }

            }

            {

  • ACL for only the port UDP Internet Permittin

    Hello

    I'm setting up a 3560 switch has 3 VLAN that is

    VLAN 223 - Server - 10.4.223.0/24 - 10.4.223.1

    VLAN 224 - user - 10.4.224.0/24 - 10.4.224.1

    VLAN 225. -internet - 10.4.225.0/24 - 10.4.225.2

    10.4.225.1 is the Gulf war to the ISP of the switch which I use as a jump on the switch.

    VLAN 225 in which an Internet service provider is talk to internet, I want to only allow only udp to 10.4.223.2. IPS of rest should not go to the internet but vlan 224 and vlan 225 should access vlan 223.

    I write access list, but it does not work

    Subnet_Vlan223 extended IP access list

    allow udp all 10.4.223.1 0.0.0.255 eq 53

    refuse the host ip 10.4.225.1 10.4.224.3 0.0.0.252 - I want to 10.4.224.3 - 254 host must be prevented to communicate with 10.4.225.1

    allow an ip

    interface Vlan223

    IP access-group Subnet_Vlan223 in

    concerning

    Sliman

    The first IP address must be the source and the destination of the second. Since it is an inbound access list, your ACL look backward.

    The deny statement may need to be written as two lines: permettre.2 to acces.1, refuse all the class C network to a.1

  • Not being able to have the remote desktop session ssh in putty

    I have cisco ASA and I have configured the ASA to have connection remotely from remote offices as well.

    I used the command ssh 0.0.0.0 0.0.0.0 outdoors where outside is my external interface in ASA.

    But, whenever I try to access the ASA of PuTTY, I get this error "network connection closed unexpectedly server."

    What can we do to solve this error and get access to the cli of my ASA.

  • Taskbar "won't go away" during Remote Desktop sessions more

    Hello.  A few weeks ago, I noticed my taskbar is more 'disappear' when I connect a desktop session remotely.  It's my phone, I always used to log in my work computer at home.  When I do that and going full-screen remote desktop, my taskbar to the laptop would be hiding and this would be my taskbar to work down as if I was sitting at my desk, normal work normally as I always knew, even when I used to use XP.

    A few weeks ago, I ran updates system and when I did, this behavior started (or stopped, depending on how you look at it).  I don't want to go through the pain of having to turn autohide on and off whenever I use my laptop to connect my system of work.

    Is there some sort of option maybe turned it while updating that I'm missing that would cause this happening now, and more importantly, that I come back to it back.

    Thanks in advance.

    I just fixed it.

    I don't know if there was an update that conflict, but I had to go to the properties of the remote desktop, make sure that it is set to "open like a normal window", click the Advanced tab and then select it to always run as an administrator.  That fixed it.

  • Should we include the NIC do not use during P2V?

    There are 2 NIC cards in a physical machine, but only one is used.

    During P2V, should we include both of them and remove one not in use on a virtual machine?  It is because we can choose the bad NIC card if we just choose a NIC card during the P2V process.

    Your opinion is requested.

    Hello

    When you perform a P2V conversion, try to remove all the devices that you do not use from the server.  This is also your chance to allocate hardware resources such as CPU or memory more or less, or adjust the allocated disk space.

    When the conversion is completed, you will need to reconfigure the network settings, so it is not really important which NIC you remove server.

    Best wishes / Saludos
