System rpc135? incoming [RESOLVED]

Hi all,

I tried search and found this -

But im not sure its the same thing im getting. At the moment I am blocking this incoming connection, is that the right thing to do??

It comes from a different ip about every hour, the destination is -my ip - port 135

I have windows updates disabled, so its not that. What else could it be & why should i allow it?

Oh yeah XP SP2 fully updated.

If you don’t experience any problems connecting to internet, leave it blocked.

Thanks for the reply gb.

Its probably something trying to contact a windows service, but as I am not having any connection problems at all I couldn’t see why I should allow it. It can stay blocked.


This is what I have had today on this -

You can find some information about ports 135, 137, 138, 139, 445 here:;msg100313#msg100313

Thanks mate, that explains it :BNC
