You're getting confused between "Client for Microsoft Networks" and "The
Microsoft Network (MSN)", Client for Microsoft Networks really means SMB
client, because it can connect to Samba, IBM Lan Server etc. "The
Microsoft Network" is that online Service that Microsoft are trying to
push, but isn't proving too popular.

But you're right, even though it may not seem such, Windows 95 does fall
back to trying netbios name resolution via DNS.. which is a bodge.

Check out the registry key
HKLM\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider\
DNSPriority REG_DWORD
HostsPriority REG_DWORD
LocalPriority REG_DWORD
NetBtPriotity REG_DWORD

these numbers are relative priorities as to how the SMB client on
Windows 95 resolved names. I *think* the lower the number the higher
priority, or it might be the other way around.

Run a DNS server locally. That way your local DNS server will catch all
DNS requests for your own domain. DNS servers are available for all
major server platforms (and no doubt your unix box you're using as a
router). Define that DNS server as the primary DNS server for your
network, and your dial-up router won't be hit with DNS all the time.
