Re: Windows 2003 Domain Controller (Open Port 593)

You are correct with the assumption that i had misinterpreted
http://support.microsoft.com/kb/826382.
After reviewing http://support.microsoft.com/kb/832017 it looks like
there is nothing I can do about the port opening as it is needed by
the OS. I should have included in my first post that the svchost.exe
was using the RpcSs services. Thank you for the quick response and
article 832017.

I have just set up a new Windows 2003 domain controller and after
setting up the DC I ran a quick nmap scan of the box and have two open
ports which concern me. They are ports 593 and 1026. I did a quick
Google and port 593 (opened by svchost.exe) is related to
http-rpc-epmap and port 1026 (opened by lsass.exe) is related to
lsa-or-nterm. I do not have RPC over http proxy enabled and just to
make sure I have doubled checked this by going to add/remove windows
components/networking services and RPC over HTTP Proxy is not enabled.
My question is how can I remove these or are they necessary services
needed by the OS. I do not have an Exchange environment and IIS is not
installed.
