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

 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#

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 configuredYou see the DFSR folders get created on the other end, but nothing stagesFinally 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-5E67-4DA1-99AC-681B5BACC7E5  Replication Group…

Fixing duplicate SPNs (service principal name)

This is a pretty handy thing to know:

SPNs are used when a specific service/daemon uses Kerberos to authenticate against AD. They map a specific service, port, and object together with this convention: class/host:port/name

If you use a computer object to auth (such as local service):
MSSQLSVC/tor-sql-01.domain.local:1433

If you use a user object to auth (such as a service account, or admin account):
MSSQLSVC/username:1433

Why do we care about duplicate SPNs? If you have two entries trying to auth using the same Kerberos ticket (I think that's right...), they will conflict, and cause errors and service failures.

To check for duplicate SPNs:
The command "setspn.exe -X

C:\Windows\system32>setspn -X
Processing entry 7
MSSQLSvc/server1.company.local:1433 is registered on these accounts:
CN=SERVER1,OU=servers,OU=resources,DC=company,DC=local
CN=SQL Admin,OU=service accounts,OU=resources,DC=company,DC=local

found 1 groups of duplicate SPNs. (truncated/sanitized)

Logstash to Nagios - alerting based on Windows Event ID

This took way longer than it should have to get going...so here's a config and brain dump...

Why?
You want to have a central place to analyze Windows Event/IIS/local application logs, alert off specific events, alert off specific situations.  You don't have the budget for a boxed solution.  You want pretty graphs.  You don't particularly care about individual server states.  (see rationale below - although you certainly have all the tools here to care, I haven't provided that configuration)

How?
ELK stack, OMD, NXlog agent, and Rsyslog.  The premise here is as follows:

Event generated on server into EventLogNXlog ships to Logstash inputLogstash filter adds fields and tags to specified eventsLogstash output sends to a passive Nagios service via the Nagios NSCA outputThe passive service on Nagios (Check_MK c/o OMD) does its thing w. alerting
OMD
Open Monitoring Distribution, but the real point here is Check_MK (IIRC Icinga uses this...).  It makes Nagios easy to use and main…
