Powershell, Windows Servers, VMware and Scriptings
In this blog, I’d like to show you the little one-liner powershell code that will delete empty folders recursively.
Note: Even if there is a single file in the child nested folder, it will exclude the parent path from deletion. Continue reading “Delete Empty Folders with Powershell Recursively”
Normally we turn on the DNS debugging to find out the source client IP addresses and the queried records. And, here is the script that will covert the DNS Debug Log file into a more flexible csv format, though you will have to rename the file to .csv if needed. New lines, whitespace and header information will be ignored during conversion. The script supports DNS Debug log of Server 2012, 2016 and 2019 (not tested on Server 2008 and if you can do it successfully, please comment). This script should not be run on Domain Controllers/DNS Servers as it consumes certain amount of processing power. Continue reading “Make a read-able windows DNS debug log file”
Sometimes, you will need to give some domain users (may be the desktop support) Network Configuration Operators role or even Local Administrator permissions on specific client machines so that they can fix something with the elevated permissions. You can do this by simply adding these users into the necessary local security groups on these machines.
Nope! it’s a boring day-to-day task and what if you forget to remove these permissions later ? Continue reading “Lockup Domain User in Specific Computer and Escalate Permissions”
Now, it’s a blogging time. Here is the little script that you can use to check the network connectivity of each portgroup in your vmware environment, which can also be used to determine if the portgroups or physical uplink (backing the vswitch) has the desired vlan access for the multiple exsi hosts.
This script will output the the VM’s ICMP Ping status after making vMotion to each host within the current vmware cluster (where the VM resides) or any clusters. Continue reading “VMware Network Portgroup Connectivity Check with Circular VM vMotion”
I recently need to check the DNS records for one of my customer’s DNS server. It’s more than 500+ records to verify that the ‘A’ and ‘PTR’ records are updated properly and which records are missing. Most of the online scripts I found only check for single PTR records. So finally, I need to get my hands dirty, spending a few hours in powershell to make a script the can verify the relationship between forward and reverse records in local or remote DNS servers.

It is the updated version [v2.1] of the script that will create users in nested OU. If you do not know how to use this script, you can see here.
I made some update changes so users ‘Names’ do not need to be unique in domain level but only in each OU. Continue reading “Updated v2.1: Create Users in New AD Domain with Old Users’ Domain Info”
It has been nearly 2 years that I wrote the script to create new AD users with the automatic nested OU creation. The original idea is to create the users from the csv file in which AD users properties are defined. The script now supports extracting the current users and OU information from old domain and use in the new domain. The script will prompt for the new domain name & passwords (optional) to put in the csv file. Continue reading “Create Users in New AD Domain with Old Users’ Domain Info”
In this post, we will install DNS service on Nano Server and manage via the DNS Manager Console from other computer. If you want to create Nano Server Image GUI wizard, you can check out here. In our post we are going to create Nano Sever Image by the Nano Server Generator powershell script that comes with installation ISO.
There will be two Scenarios in our testing and you can just use either depending on your environment. Continue reading “Install and Manage DNS Server Running on Nano Server”
Again, It’s time to script, making life easier with the system admin’s boring tasks. Most of us have testing environment in which we have to play with snapshots (so called checkpoints in Hyper-V).
This script will list the VMs snapshots with the last VM power-on time. This is particularly useful in cases where you want to keep the snapshot until the VM is rebooted and proved to be fully functional after any configuration changes. Continue reading “PowerCLI Script to List VM Snapshots with Last VM Reboot Time”
Here is the PowerCLI one-liner command to find the Datastore Name, Mounted URL and Device ID in your vSphere Environment.
Assume you’ve installed VMware PowerCLI. Continue reading “How to use PowerCLI to list Device ID, Mounted URL of Datastores in VMware”
