Since the SSIS packages are not in MSDB, I did the following:

1. Right click on MSDB

2. Import package

Inside Import package window:

Package location: SQL Server

Server: servername

authentication: windows authen

Package path: \\server\C$\folder1\SSIS Packages\folder2

Import package as:

Package name: package.dtsx

Below is the error I am getting:

TITLE: Import Package

------------------------------

Cannot find folder "\\server\C$\folder1\SSIS Packages\folder2".
