Server 2008 R2 SP1 RDS Servers losing connection to samba shares RRS feed

  • Question

  • Here's the scenario:

    We have a cloud hosted RDS environment with 4 RDS servers accessed through a gatway server.

    We are using DFS for the shares. (All using a letter mapped drive depending on the mandatory profile being used)

    All the RDS servers are Server 2008 R2 with SP1

    Using Samba version 3.5.5

    The shares are being hosted on a Unix Solaris 10 server.

    The problem seems to be random in time and location. One day, you'll see one of our RDS servers lose connection to all samba shares. You won't be able to find the shares via samba name nor IP address. Another day, you'll see just one specific samba share drop. Another, you'll see the samba share be accessible via IP address but not the samba name. Even though the shares are not accessible one minute, they become available again 10 minutes later without even doing anything. Worst case scenario, we've had to reboot the RDS server in order to restore connectivity to the share. The Windows logs don't show any errors regarding a loss of connectivity or remote desktop service errors. In fact, people can still access their desktop on the server, they just lose connectivity to the share, sometimes during use. This has happened on each one of the servers, sometimes simultaneously with another server, sometimes just one server at a time. The loss of connectivity has happened during high user load and low.

    I guess the question is: Has anybody experienced the random dropping of DFS samba shares from a Windows Server 2008 R2 SP1 Remote Desktop Services environment? Even better if the problem was experienced when the share is on a Unix Solaris 10 server using Samba 3.5.5.
