When I run a report it says "The RPC hotfix is not installed on this server."

Can anyone help with the paticular hotfix this message is referring to ?

Please go to www.windowsupdate.com and see if there's any available hotfix.

Also provide some details of your system configuration.

Everything is up to date .. according to windows update.

I think it may be the fact that I've enabled windows firewall on my firewall
... what ports do I need to open to allow DFS replication ?

ok I've had a look at our domain policy for windows firewall for fileservers
and

File and print sharing is enabled with the following ports open :

UDP 137
UDP 138
TCP 139
TCP 445

Remote desktop is enabled with

TCP 3389

And I've just enabled RPC

TCP 135

Now I no longer get the error "The RPC hotfix is not installed on this
server." in the diagnostic report. However I now get "Cannot retrieve version
vectors from this member."

I must need to open other ports .. anyone know which ones?

Distributed File System
The Distributed File System (DFS) integrates disparate file shares that are
located across a local area network (LAN) or wide area network (WAN) into a
single logical namespace.

System service name: DfsApplication protocol Protocol Ports
NetBIOS Datagram Service UDP 138
NetBIOS Session Service TCP 139
LDAP Server TCP 389
LDAP Server UDP 389
SMB TCP 445
RPC TCP 135
Randomly allocated high TCP ports TCP random port number between 1024 - 65534

Seems to suggest I open up ports 1024 - 65534 !?

Windows firewall doesn't support port ranges .. do I have to disable the
firewall ?

No don't open that range of ports.

Leave that closed.

Also refer to:

(Network Ports Used by DFS)

Try disabling the firewall and see if you are still getting this error, so
you will know if it's a firewall issue or not.

Ok.. !?

My firewall is now disabled .. so that proves its the Windows firewall - so
what do I need to open on the firewall to allow this all to run?

Cross posting to DFS NG.

Also you have missed out opening UDP 445 and 137 for both TCP and UDP.

On the random port, let's see what the experts from the DFS group has to
say.

You can assign DFS Replication to a static port by using Dfsrdiag, the DFSR
command-line tool. This will allow DFSR to work through a firewall.

The RPC hotfix is described at
http://support.microsoft.com/default.aspx/kb/908521. We recommend installing
this on all DFSR servers since it fixes a condition where replication could
fail and no errors would be logged.
