    IPS is stopping an exploitation attempt, are you sure you want to do this? You confirmed it's a false positive?

    Create a firewall rule to allow the traffic and also set up and excluded host for the IPS

    But it seems happened on this pc only. Not heard other users report same problem.

    Please advice.

    Thanks

    Is it continuous or just a one time thing? Ideally, you want to confirm this is a false positive and not exclude any hosts from IPS

    Continuous happening.

    Yes, at least I can use VNC to remote this PC.

    According to the link you posted, upgrading to a later VNC version fixes the vulnerability which should take care of this problem. That's the best course of action in this case.

    IPS are bound to generate false postivie alarms some times. You may need to create an execption for this SID,

    open policies

    IPS

    Edit

    Windows exceptions

    click on Add

    search for this SID

    Make it to allow, that would fix the issue

    If you're 110% certain this is a false positive then you can create an exception.

    I would tread lightly here though....make sure you're VNC is fully up to date

    may be the policy did not get applied to this PC, program version, request pattern, lot of things at the backgroupd.
