Access is denied connecting to SSIS instance

Hi Everyone,

I have followed the steps provided in link below but still teh user not able to connect to integration services through SSMS.

https://www.mssqltips.com/sqlservertip/3086/how-to-resolve-ssis-access-denied-error-in-sql-server-management-studio/

The SQL Server Integration Services 13.0 , I can connect using SSMS 2016. But others users get Access Denied error. They are part of DCOM config.

This service is running under Local System account on server can that be causing this issue ? Which account this should run under and how to change that now ? also any other input on access issue will be very helpful.

Thanks much.

Best Regards, Pragati
