Registering SQL Server Not In Domain

Hi all,

We have standardized on Hyperion as our reporting tool. So far I have
only set up a couple of Access databases as data sources for it. Now
there is a request to report off our eOn (telephony management) SQL
Server database using Hyperion. The eOn SQL Server box is in a
workgroup that is not part of the rest of our domain. (We only have
one domain because we don't have a "forest", whatever that means.) It
is behind a router owned by eOn along with a PBX and some other stuff.


Setting up a data source for Hyperion requires creating a special data
source file called an .oce on the box where the Hyperion fat client
(required for most administrative tasks) resides, and also setting up a
different special data source file called a .das on the server where
the Hyperion services run. (The analysts and end-users do not have the
fat client, their access is web-based.)

I have to register the eOn SQL Server by using the IP address and SQL
Server authentication. (I was told that I can't use Windows
authentication because it is not in the domain.) From the box on
which the Hyperion fat client resides, I cannot register the eOn SQL
Server. The error message is "timeout expired". Tracerting indicates
there are no intermediate hops when attempting to connect from this
VLAN. From my desktop, which is on a different VLAN, I can connect to
and register it. This trip includes one hop at our 6509. From one of
my servers which is on the same VLAN as the fat-client box, I am able
to connect and register. On the fat-client box I tried deleting and
re-registering another SQL Server and there was no problem.

The IP address I have to use to connect to the eOn SQL Server is *NOT*
the actual IP address of the box it resides on, but rather the eOn
router, which translates it to the address of the server. We have no
control over this, eOn creates this setup. I'm not sure how it knows
which of the devices behind it a given message is for.

Ideas?
