SQL Server Intigration Services Connectivity Issue

I am trying to connect SSIS 2012 from management studio on my local system.

But I am receiving below error while connecting

1. Run Dcomcnfg.exe. Dcomcnfg.exe provides a user interface for modifying certain settings in the registry.
2. In the Component Services dialog, expand the Component Services > Computers > My Computer > DCOM Config node.
3. Right-click Microsoft SQL Server Integration Services 11.0, and then click Properties.
4. On the Security tab, click Edit in the Launch and Activation Permissions area.
5. Add users and assign appropriate permissions, and then click Ok.
6. Repeat steps 4 - 5 for Access Permissions.
7. Restart SQL Server Management Studio.
8. Restart the Integration Services Service.
   
   
   Same process has to be followed all the options in security tab(Access Permissions and Configuration Permissions) .
   
   
   This resolved my connectivity issue.

Shrink all databases log file at a time

drop table #f
go
create table #f (name sysname, fileid int, filename sysname, filegroup sysname null,
size sysname, maxsize sysname, growth sysname, usage sysname)
go
exec sp_MSforeachdb 'declare @s varchar(MAX); use [?];
truncate table #f; INSERT #f (name, fileid, filename, filegroup, size, maxsize, growth, usage )
exec sp_helpfile
--select * from #f

 select @s = ''use [?]; DBCC SHRINKFILE ('' + name +'',0,truncateonly )'' from #f where usage = ''log only''
print @s'
