    I would make sure to deny it access when it comes up. The port is used to exploit some loopholes.

    Now lets get some things straightened out - the grc.com reference for the risks concerning the open port (server) TCP 135 is strictly to the internet and/or an untrusted LANs, not to the trusted zone (which is okay).
    Really the issue for the 135 is for an internet address and not concerning the 0.0.0.0 or the localhost address (127.0.0.1) loopback. (the loopback is a trusted address, and really so is the 0.0.0.0 address)

    Some computers will never have the svchost.exe listen on the 0.0.0.0:135 - it all depends on the services/daemons enabled in that particular windows.
