Users keep disconnecting from network share - Windows 7, Windows Server 2008 RRS feed

  • Question

  • Hello,

    some stations are disconnecting from the network, and I have no idea why. One of the computers logs off every day, around 6-8 p.m. Other computers disconnects randomly. After disconnecting, it is not possible to connect again - we have to reboot the computer, and then it works. But it is very annoying, having to do this every day, and it is quite problematic when an user is using a file on the network, and then he/she is disconnected - it takes a long time for the file to be saved locally, for some reason.

    I tried a clean install of Windows on one computer, but the problem continues.

    I also tried going to Local Security Policy > Local Policy > Security Options > Microsoft network server: Amount of idle time required before suspending session and setting it to 99999 minutes, but it didn't work as well.

    Is there an option where the computer logs off automatically after x hours of connection, or after x hours of inactivity, or something like that? Is that a problem on the computers (running Windows 7) or on the server (running Windows Server 2008)?

    One of the stations is running Ubuntu 12.04 and it never got this issue so far.

    Thank you in advance,

    Leonardo

  • Hi,
     
    According to the symptom, the cause of the problem is a DNS problem, network reachability problem or something hasn’t been noticed.
     
    We can do some tests to narrow down the issue.
     
    ·Are you using the hostname or ip address for network sharing? If you are using the hostname, the DNS maybe have some issues. After the DNS cache aged, clients can’t resolve the server.
    ·Can you ping the server from the client which disconnected from the network sharing? If the ping is time out, it may be the network reachability problem.
    ·Can you telnet the server from the client with the port which used for network sharing? If the client can’t connect to the server with the port, you should check is there any filter between the server and client. If the server could be connected, check is there any programs using the same port.
     
    If all these tests are passed, check that is there any authentication problems.
     
    By the way, when you try to reconnect the server, is there any message reported?
     
    Notice: You can use netstat –n to find the port which used for network sharing.
     
    Hope this helps.
