LAN connection, AND by monitoring the bytes exchanged over the NIC.
on PC1 is currently set to "auto" but I've tried setting it to 100FD as
known better ;-), but yes, PC 1 has a second NIC connected to an ADSL modem.
PC 2 connects to the outside through Windows ICS.
for sniffers ?
Thanks very much for your help so far,

that really brought my hopes up, but unfortunately it didn't work. I was
already logged in as Administrator but logging in under a different account
made no difference.

machines can see each other since file sharing is working, and I'm
assuming ping also works. I'd suggest trying to disable ICS, the
firewall, and also the second nic, then restart the pc and see if that
You should also run the arp -a command on both machines and make sure
that the ip number of the other machine matches it's hardware address.
Since everything else seems to work, this is probably all ok, tho, but
it can't hurt to check.
FWIW, the ICS software isn't exactly the most standards compliant bit of
code out there in the world, and if you're doing work on both pcs, using
a local firewall and ICS for the uplink isn't the most secure way to go
(although the fact that you'd taking any measures puts you way ahead of
most folks). Might be worth considering a little hardware NAT for the
uplink, depending on how much security you think you need balanced
against the cost.
What I'm thinking is that one possibility is one or both of the machines
(but probably the one running the ICS) is confused about how to handle
broadcasts, might be munging either the ip number in the header or might
be using the wrong hardware address. What I'd expect to see is one or
more broadcasts from PC2 when you open the hosts lists, followed by a
unicast back from PC1, starting a brief conversation with a list of
databases. In any case, if you sniff the conversation, you can see
what's going on.
As an example, under OS X from my mac, when I open remote in filemaker,
my workstation sends out a UDP broadcast to 220.127.116.11 port 5003 (I'm
on the 18.104.22.168 network). Our fmserver machine, also OS X, sends back a
UDP packet from 5003 to the workstation. Then they switch to TCP and the
list of hosts is exchanged.

thanks for all your suggestions. In the end I decided that it was time to
finally upgrade the network, incorporate 2 more pc's that had been working
stand-alone up to this point, AND take Filemaker up on their offer for a
free copy of version 6, if a full version was bought before December 15th. I
decided to bring everything together with a Linksys Router/Switch.
So now I have 4 pc's networked, 3 of which are currently running FM. PC 1 is
running version 6, the other 5 and 5.5. And who would have thought it ? My
problem has gone away... PC1 shows up fine as the host on PC2 and PC3 !
Finally got rid of ICS as well, so I guess it's a good thing altogether.
It really bugs me that I had to "solve" the problem with this sledge hammer
method, but in the end I figured it just took too much of my time and the
risk of data corruption was too high. Although I still don't know what the
cause was and whether it was Filemaker or TCP/IP related, the most important
thing is everything is ok again.
I really want to thank you for the time you've put into this problem. Hope I
can help you somewhere down the line.
