Domain Account Keeps locking out

One domain user's account keeps locking out. I have checked the credential manager to remove all without luck till I found this article at this link, https://joshancel.wordpress.com/2017/01/10/hidden-stored-credentials/.

Summary:

To resolve I found these below steps.

Download PsExec.exe from http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx and copy it to C:\Windows\System32 .
From a command prompt run:    psexec -i -s -d cmd.exe
From the new DOS window run:  rundll32 keymgr.dll,KRShowKeyMgr
Remove any items that appear in the list of Stored User Names and Passwords.  Restart the computer.

Unlock worksheet vs unlock workbook

Scenario 1
Unlock worksheet ( file is open but Workbook is protected)
Solution: upload to Google Docs and download as regular Excel file.

Scenario 2

Back up CUCM and UNITY to SFTP server on Windows Server

I'm replacing an old Window 2003 server hosting freeFTPd app for Cisco Call Manager and Unity backup files with a Windows 2008 R2 server.

I got the freeFTPd downloaded to the new server but had very hard time to get it to work. CUCM could not communicate with it. WinSCP could not connect to it either. After messing around the firewall settings, I gave it up on freeFTPd.

Then I decided to try the free version of SolarWinds SFTP/SCP server, WOW it only took me few minutes to get the backup to work.

On SFTP server, create the root directory, I also created two sub-folders to separate backup files between CUCM and UNITY.

 Create a new user. The credential will be used in CUCM and UNITY.

 Make sure the SFTP server is running.

On CUCM, go to Disaster Recovery System, create a new backup device.
Host name/IP address: enter the IP of the Windows server running SFTP
Path name: /CUCM (the sub-folder created in the root directory)
Username and password: same credential created in SFTP


It worked much better than the setup with FreeFTPd server based on my experience.
