Integration Services Configuration on Cluster

I've followed the books online help to configure SSIS (move the
MsDtsSrvr.ini.xml file, edit the file to have the correct path virtual server
name, and change the registry), restart all services...and nothing. I can
connect to SSIS fine through Management Studio, but when I click on Stored
Packages -> MSDB it hangs and eventually times out with this error message:
"The SQL Server specified in SSIS service configuration is not present or is
not available. This might occur when there is no default instance of SQL
Server."
I have a no default instance of SQL 05 on a failover cluster.
Also, I've tried every possible combination on the Server section of the
MsDtsSrvr.ini.xml file: server name\instance name, cluster name-.
Is it a dash or a backslash, I've seen different advice in articles, also.
thanks!Perhaps the configuration file isn't on the shared disk and available to
both nodes?
Please check out this article:

of the required configuration.
