Create a new maintenance plan

I have installed SQLServer 2005 from Small Business Server premium edition. The package has been upgraded to SP2 and all the fixes have been applied.

I want to create a new maintenance plan to automate my DB backup procedures using SQL Server Management Studio. I start Management Studio and right click on the management folder and I I see is "Refresh" there is no "Create New Maintenance" plan presented.

I have tried this using the sa built-in account and the server administrator account both of which have sysadmin priviledges. I have also tried it from a client machine with another sysadmin userid but they all give the same results.

I checked to see if SSIS was installed. The add/remove programs wizard for SQL Server shows Integration Services SP2 is installed but I went ahead anyway and re-installed without error.

It seems that either SSIS is not running or I my user roles are preventing the maintenance wizard from running. Is there some way that I can tell if, in fact, SSIS is properly installed and running?

Thanks.

To create or manage maintenance plans, you must be a member of the sysadmin fixed server role. Note that Object Explorer only displays maintenance plans if the user is a member of the sysadmin fixed server role.
