Windows firewall blocks TCP Port 135 (RPC Portmapper) and 445 when i enter an IPv6-Address in GPO (Allow inbound remote administration exception)


  • This problem occurs when i enter this in the local Policy or in a Domain Policy.

    The Problem also occurs, when i enter syntactic incorrect values in this Entry.

    In a Domain Network this is fairly fatal !!!!

    All Domain Computers have Connection Problems and we must reboot all Domain-Controllers after we found the Problem.

    I have tested the isuue in Server2012,Server 2012 R2,Windows 8,Windows 8.1.

    How can i enter an IPv6-Address in this GPO-Setting ?

  • Hi Jens,

    >>How can i enter an IPv6-Address in this GPO-Setting ?

    Before going further, how did we input the IPv6 address? As stated in the following article, for this policy setting, IPv6 traffic supports the * and LocalSubnet scopes.
