Connection to the Integration Services service on the computer " XXX " failed with the following error: "Access is denied"
By default only administrators have access to the Integration Services service. The process must be running with administrative privileges in order to connect to the Integration Services service.
For users who have worked with older versions of SQL Server, this can be surprising as connecting to SSIS with SSMS usually does not have problems. The reason for this is that in the older versions, all users of the "Users" group had access to SSIS by default. In the newer versions of SQL Server, however, access is secure by default and it must be granted to a specific user who needs to connect to that service.
