Solution:

2. Verify that this computer can reach the SQL Server computer.
3. Verify that SQL Server services are running.
4. Verify that SMS can access the SMS site database.
5. Verify that the SMS site database, transaction log, and tempdb are not full.
6. Verify that there are at least 50 SQL Server user connections, plus 5 for each SMS Administrator console.

If the problem persists, check the SQL Server error logs.

Possible cause: Low disk space on the drive containing the package source files.
Solution: Make more space available on that drive.

Possible cause: The package source files are being written to a remote computer that is not accessible.
Solution: Ensure that the remote computer is running and accessible.

Possible cause: The package source files exist, but something other than SMS has changed the permissions or attributes of the files or the directory containing them.
Solution: Restore the files' permissions or attributes so that this SMS service can access the files.

Possible cause: The package source files exist, but they are corrupt.
Solution: Delete the files and replace them with backup copies.
