    Hi,

    What may be the impact if we install Symantec with NTP and without NTP?

    Any traffic gets affected due to that?

    Hello,

    What version of SEP 12.1 are you running?

    Here is an Article which explains: Default Symantec Endpoint Protection 12.1 RU1 Firewall Policy

    http://www.symantec.com/docs/TECH180569

    I would suggest you to follow the Best Practices - Best Practices for Installing Symantec Endpoint Protection on Windows Servers

    Also, check this Article:

    About Windows Firewall and Symantec Endpoint Protection's NTP

    Hope that helps!!

    Hi.

    We use NTP with an ALLOW ALL policy. This means we don't block any traffic, but it is still inspected for maliceous content/activity.

    For us, we see no difference in performance or server load. Admittedly, we have not taken any measurements with tools on a before & after basis. This is more from talking to users and our own experience.

    One issue we had that NTP made worse is ghosted NICs on VMware guests. See this MS article if you want more info: http://support.microsoft.com/?kbid=269155

    Hi,

    As per this document..it is telling as when symantec is installed with NTP it automatically disables the windows firewall..

    is it true? really symantec will disable the windows FW?

    you need to tune up policy to meet your requirement.
