Firewall and Registry Settings for DCOM
DCOM dynamically allocates one port per process. You need to decide how
many ports you want to allocate to DCOM processes, which is equivalent
to the number of simultaneous DCOM processes through the firewall. You
must open all of the UDP and TCP ports corresponding to the port numbers
you choose. You also need to open TCP/UDP 135, which is used for RPC End
Point Mapping, among other things. In addition, you must edit the
registry to tell DCOM which ports you reserved. You do this with the
"HKEY_LOCAL_MACHINES \Software \Microsoft \Rpc \Internet" registry key,
which you will probably have to create.
The following example tells DCOM to restrict its port range to 10 ports:
Named Value: Ports
Type: REG_MULTI_SZ
Setting: Range of port. Can be multiple lines such as:
3001-3010
135
Named Value: PortsInternetAvailable
Type: REG_SZ
Setting:"Y"
Named Value: UseInternetPorts
Type: REG_SZ
Setting: "Y"
These registry settings must be established in addition to all firewall
settings listed below.
