Named instance connection problem

Have an MSDE named instance which works just fine. Just installed
another instance of the same and can only connect to it using OSQL
locally, nothing across the network. I made sure to use all the
gotcha flags during install to enable network access, etc:
setup.exe DISABLENETWORKPROTOCOLS=0 SAPWD="sapassword"
INSTANCENAME="instancename" SECURITYMODE=SQL /L*v
c:\temp\msdeinstlog.txt
After the install and reboot, also verified that network access is
allowed using SVRNETCN, where both named pipes and TCP connections are
enabled.
Tried connecting using "sa" and trusted NT auth and both work locally,
but across the network it's always:
[DBNETLIB]SQL Server does not exist or access denied.
[DBNETLIB]ConnectionOpen (Connect()).
No firewalls in the way from client to server. As a matter of fact,
when I telnet to the TCP port shown in SVRNETCN, the connection is
established, so the port is obviously open.
I'm racking my brain on this one... What gives?
Thanks guys,
-Peter.

Starting with SQL Server Desktop Engine (also known as MSDE 2000)
Service Pack 3 (SP3) or SP3a , only local connectivity is permitted, by
default. If you want to permit remote connections to SQL Server Desktop
Engine, follow the steps in the following article:
