Problem opening MSDB folder under Stored Packages

I am able to connect to Integration Services in MSSMS. However, when I try to expand and click on MSDB under Stored Packages, I get a Login Timeout expired error. I get this error both locally, and remotely. Error message suggested "does not allow remote connections", but I checked Surface Area Configuration, and remote connection is already enabled. Moreover, I get the same error even when connecting locally.

any ideas?
Do you have a default instance of SQL Server installed in that machine?|||No, it's a clustersql
