Hostname Issues with Win 95 Client (Ping)

Hi - having a bit of problem with my win95 (urgh!) clients...

The Setup:

We have a sbs2000 multihomed server with a slightly odd pair of Ip addresses
(not setup by us)

The internal IP is 111.111.111.150 with subnet 255.255.0.0

The external is 10.0.0.11 subnet 255.0.0.0

And no, i haven't got that wrong....

The external address goes to a firewall - which is why it is a 10.0.0.11 and
not a "proper" external IP. (please excuse my improper use of
terminology...)

We have ISA running on the server, as well as exchange, and it is a domain
controller and DNS Server (like most SBS boxes i presume)

The problem:

If a win95 client pings the server it will occasionally resolve to 10.0.0.10
and other times resolve to 111.111.111.150. This seems to be causing some
problems with MS Outlook trying to connect to exchange - it should just
resolve to the internal address (111.111.111.150).

We have win98 and winxp clients on the network too, and these seem
unaffected. For the moment I'm looking at editing the lmhosts file - please
correct me if there's a better (server-side?) fix.

Thanks in advance,

Ewan

They didn't do you a favour on this one but a quick check suggests the
111.etc network doesn't exist so it's no biggy actually.

using 10.0.0.x between the external interface of your server and the router
looking after your internet connection is a perfectly valid configuration,
nothing wrong here.

I'm half asleep and haven't used '9x for ages, but this sounds like
http://support.microsoft.com/?id=292822. Yes, you may have applied the SP,
but you also need to do the regedits.

Looks like you could be right! - we have RRAS setup, and have also had a few
of the other symptoms described in the article.

I'll try those edits and see what happens.

many thanks for the prompt (and thorough) reply!

Ewan.
