Local admin password changes en masse

Another handy project.


First and foremost, follow this process when changing the passwords:

  1. Create Excel file with servers/passwords
  2. Import into your password manager
  3. Use that Excel file as the basis for the 'serverpasslist.txt' file

How to use
# Open a command prompt with appropriate DA credentials.
# Browse to the directory containing the batch file, list file, and Sysinternals tool files.
# Run the batch file.

If there are issues, like the computer name does not exist, you'll see this:
---------------
 E:\scripts\sysinternals>serverpasschange.bat

 PsPasswd v1.22 - Local and remote password changer
 Copyright (C) 2003-2004 Mark Russinovich
 Sysinternals - www.sysinternals.com

 Error changing password:
 '''The RPC server is unavailable.'''
---------------
Script
See below for sources.  Removed the echoing to help with visual security.  Removed extra parameters as they are not necessary.
---------------
 @echo off
 set FILE=serverpasslist.txt

 for /F "skip=2 tokens=1,2*" %%i in (%FILE%) do (
  echo %%i
  pspasswd.exe \\%%i.domain.local administrator %%j
 )
---------------
As a note on this script, I left the 'echo %%i' line in because if a change fails, the pspasswd.exe command doesn't print out the name, so viewing the failed cmds at the end now has the name above the fail message.

File structure
Spacing is tab-delimited - handy for copying out of Excel.

 Target NewPassword
 -------------------------------------------------------
 SERVER01 Password1!
 SERVER02 Password2@
 SERVER03 Password3#

Learning through failure - a keyboard creation journey

Image
tl;dr Built a custom keyboard cuz I have weirdo nerve pain issues.   Learned a lot cuz I failed a lot.   Maybe 'do it right the first time' is a bad frame of mind.   The keyboard ended up being kinda nifty.   It has lights, and a trackball, and QMK, and it helps my issues.   \o/ ( tl;dr is internet lingo that means, too long; didn't read ) Pain as a key ingredient An old proverb says, 'necessity is the mother of invention', and that is how this story begins. Over the last few years, age or stress or something has caught up with me and I developed the need to change my human-to-computer interface.  Mousing changed to trackballing.  The traditional keyboard was swapped out for an ergonomic, and then split keyboard.  Complicated multi-finger-and-hand key combinations were replaced by single keypress macros.  And yet more was still needed. It's often said that change only happens with pain - indeed, the organizations many of us work in seem to apply this as law - an

Learning Opportunities - Watching/listening list

Over the last year I've spent a lot of time learning (thank you, long commute & lunch hours).  Many topics ranging from Chef to DevOps to architecture concepts to management concepts and everything in between.  Why have I done this? DevOps Demystified with Ben Rockwood: https://www.youtube.com/watch?v=h5E--QSBVBY DevOps at ancestry.com: https://www.youtube.com/watch?v=pF5ya0q53kk Those two presentations were key in sending me down this road.  First, and most important, was Mr. Rockwood's explanation as to the real 'why', and the point behind DevOps from an operational perspective.  Second, and no less important but for a different reason, the continuous delivery system at ancestry.com really made it real to me because they are a 'Windows shop'.  So much of what I'd been reading about Chef/config mgmt. relied on amazing tools (see the error there?) only available to the Linux world.  Suddenly here's this guy telling me that it's possible on

DFSR - eventid 4312 - replication just won't work

This warning isn't documented that well on the googles, so here's some google fodder: You are trying to set up replication for a DFS folder (no existing replication) Source server is 2008R2, 'branch office' server is 2012R2 (I'm moving all our infra to 2012R2) You have no issues getting replication configured You see the DFSR folders get created on the other end, but nothing stages Finally you get EventID 4312: The DFS Replication service failed to get folder information when walking the file system on a journal wrap or loss recovery due to repeated sharing violations encountered on a folder. The service cannot replicate the folder and files in that folder until the sharing violation is resolved.    Additional Information:  Folder: F:\Users$\user.name\Desktop\Random Folder Name\  Replicated Folder Root: F:\Users$  File ID: {00000000-0000-0000-0000-000000000000}-v0  Replicated Folder Name: Users  Replicated Folder ID: 33F0449D-5E67-4DA1-99A
