Lo mejor es que via Group Policy, en la parte de Windows Firewall actives:
"Allow local program exceptions". Esto pertirá los siguientes puertos en las
maquinas cliente:

TCP Port 135 for (DCOM) (DCE/RCP Endpoint Mapper)
TCP Port 445 for (RPC)

Copio el texto de ayuda: "
Allows remote administration of this computer using administrative tools
such as the Microsoft Management Console (MMC) and Windows Management
Instrumentation (WMI). To do this, Windows Firewall opens TCP ports 135 and
445. Services typically use these ports to communicate using remote
procedure calls (RPC) and Distributed Component Object Model (DCOM). This
policy setting also allows SVCHOST.EXE and LSASS.EXE to receive unsolicited
incoming messages and allows hosted services to open additional
dynamically-assigned ports, typically in the range of 1024 to 1034.
If you enable this policy setting, Windows Firewall allows the computer to
receive the unsolicited incoming messages associated with remote
administration. You must specify the IP addresses or subnets from which
these incoming messages are allowed.
If you disable or do not configure this policy setting, Windows Firewall
does not open TCP port 135 or 445. Also, Windows Firewall prevents
SVCHOST.EXE and LSASS.EXE from receiving unsolicited incoming messages, and
prevents hosted services from opening additional dynamically-assigned ports.
Because disabling this policy setting does not block TCP port 445, it does
not conflict with the "Windows Firewall: Allow file and printer sharing
exception" policy setting.
Note: Malicious users often attempt to attack networks and computers using
RPC and DCOM. We recommend that you contact the manufacturers of your
critical programs to determine if they are hosted by SVCHOST.exe or
LSASS.exe or if they require RPC and DCOM communication. If they do not,
then do not enable this policy setting.
Note: If any policy setting opens TCP port 445, Windows Firewall allows
inbound ICMP echo request messages (the message sent by the Ping utility),
even if the "Windows Firewall: Allow ICMP exceptions" policy setting would
block them. Policy settings that can open TCP port 445 include "Windows
Firewall: Allow file and printer sharing exception," "Windows Firewall:
Allow remote administration exception," and "Windows Firewall: Define port
exceptions"
