Greetings.
I have created a new Windows Server 2008 Core Enterprise Edition
server, that I am going to use with Hyper-V to run a couple of test
servers (hopefully I will be able to make them production once Hyper-V
is RTM'ed).
I have been able to change its IP, join it to the domain. I have
enabled remote management through the firewall. Using another Windows
Server 2008, I am able to use a domain account to connect to the Core
server with Computer Manager and the Firewall MMC as well.
The only thing I seem to be unable to do in Computer Manager is use
the Disk Management part of Computer Manager. Every time I try, I get
the pop-up error "The RPC server is unavailable".
I have even gone so far as to turn the firewall off completely on the
Core server just to remove that as a potential issue, which did not
help.

The only clue I seem to have is that I have the following event log
entry on the server:

Has anyone run into this before?

I am running this server on a system with an Intel ICH9R RAID
controller. I have 4 disks in a RAID 1+0 configuration. I have tried
the current publicly available driver/chipset pack from Intel, and a
pre-release pack to see if that had anything to do with this error.
Nothing seems to make the error go away.

I would really like to get the remote disk management piece working so
I can carve up the RAID 1+0. Also it would be nice to have a machine
where I didn't have any errors in the logs (warnings or not) before I
started using it.

Sorry, I don't have a solution at this time, but I'll continue to
investigate of and on - not sure if I'll find a solution or not.

For Windows XP, Server 2003 the Program Exceptions listed below are required
to allow remote disk management. I think the relevant entries are the ones
for dmadmin.exe and dmremote.exe (this is extracted from the settings report
in GPMC for the GPO I use to enable the Windows Firewall).

With these settings, I could use Disk Management from a Windows Server 2003
SP1 computer to manage disks on a Windows Server 2008 Full Installation that
has the Windows Firewall enabled (actually formatted a partition remotely).

However, from Vista SP1 (sorry, don't have second 2008 server in this
environment) I got the "The RPC Server is Unavailable" and then in the
Computer Management Status (bottom of the right pane) "Unable to connect to
the Virtual Disk Service". Seems that Vista (and presumably Server 2008)
are using a different mechanism than Windows Server 2003 to communicate with
the disk management services remotely. (Using Computer Management from the
Vista computer I was able to do other remote management tasks - e.g.
start/stop services, create/manage shares, view Event Log Entries).

I turned on logging in the Windows Firewall on the 2008 server, but nothing
was reported as being blocked.

It's perfectly useless to know the right answer to the wrong question.
