  • 7011 Errors, RDP Busy, must reboot

    We have been having this issue for the past two months almost daily.

    The symptoms:
    -Multiple 7011 errors triggered referencing timeouts for nlasvc, cryptsvc, and lanman workstation.
    -Users are unable to log on to the RDS server.
    -Unable to access the remote desktop management console.

    The problem will not resolve on its own and the server cannot be shutdown. A hard reboot (pressing the power button) is the only way to stop the issue. The errors start happening after a user has logged off (no particular user, always someone different). If we have the users stayed logged on throughout the day the issue does not appear. This server is our primary application server and the only server actively being used. (No separate licensing servers, data servers, ad servers, etc.)

    Our setup:
    HP ML350 G6
    Server 2008 R2
    Xeon Processors
    12GB RAM
    Symantec Endpoint
    Office 2007

    Our efforts thus far:
    -Hotfixes KB2383928, KB980663, KB979530
    -Removed XPS Document Writer and various redirected printers
    -Forced Printer Driver Isolation Mode vis GPO
    -All drivers and firmware updated as well as windows
    -Disabled IPv6
    -Installed latest Symantec Endpoint 11.0.6 MR2
    -Uninstalled all backup software.
    -Disabled unnecessary printer services (AppleTalk, Netware, etc)
    -Removed HKEY_Users\Default\Software\Hewlett-Packard registry key (VERY BLOATED)

    There seem to be several others who have this issue as well with no resolution. I am at a loss and rebooting a production server daily is unacceptable.

    Thank you far in advance for any suggestions or comments!!!

    1. Please enable IP v6.

    2. Is the RDS settings point to itself as license server?

    3. Is the SEP was installed with Proactive protection etc.? If so, please remvoe it and reboot.
