Remote connections to named instances fails on SQL 2005 cluster

I have a new SQL Server 2005 cluster with multiple named instances of SQL
Server 2005 running. From any cluster machine, I can connect to any instanc
e
of SQL Server running in the cluster. From remote machines, I can connect t
o
the default instance of SQL Server, but I can not connect to any named
instances. Help?
+ SQL Browser is running on one physical machine in the cluster
+ Surface Area Configuration has "remote clients" enabled for all instances
+ Named pipes and TCP/IP are enabled
+ DTC is running on the cluster. It is configured to allow network access
on each physical machine.
+ Windows firewall is disabled. Remote machines on same subnet as cluster
machines.
+ Client machine can ping virtual servers?
After waiting a few hours, remote connections now work
?
