#1334 Connection has been gracefully closed


Hi, we are using tightvnc in our Windows network. Most pc's are W7, but some vista's are still in use. On these computers we get an error 'connection has been gracefully closed'. I've tried everything i found on Google, but to no avail. Anyone any ideas? No log entries in Windows logs.

    I have the same problem. I updated yesterday (2014.09.03) some PCs with the latest Microsoft Updates and when I log-in to VNC the connection is closed.

    I can confirm this error. I think it has to do with the remote display being asleep. After it wakes up the error goes away.

    Same problem after installing a new machine.
    Found the reason to be the mirror driver.

    As soon as the MD has been deinstalled, everything worked fine again, including when display is locked or sleeping.

    Server-Client both Win7-64.
    TightVNC 2.3.7
