Read-only first. Built for real troubleshooting.
PowerShell Library
KrippyTech's PowerShell Library provides reviewed troubleshooting tools for technicians and administrators. Test-KTDNS v1.0.0 is the first public release: a read-only Windows DNS troubleshooting script.
What the library covers
The library is organized around discovery and triage work that repeats across real support cases. Public scripts are released individually after their documentation, safety boundaries, tests, and packaging have been reviewed.
Active Directory
Domain & server health
User and computer discovery, group membership, FSMO roles, domain controllers, replication, SYSVOL and DFSR, time sync, secure channel, GPO inventory, and server health.
Windows & network
Fast path troubleshooting
DNS queries, routes, TCP tests, interface details, event-log snapshots, and reusable network triage for common connectivity and service-access problems.
Second public PowerShell release
Get-KTNetworkConfig v1.0.0
Get-KTNetworkConfig v1.0.0 is a read-only Windows PowerShell tool for discovering the local network configuration of active adapters.
Structured discovery
Eight stable properties
It returns structured PowerShell objects containing the interface alias and index, adapter description, IPv4 and IPv6 addresses, IPv4 gateways, DNS servers, and network profile.
The script performs local discovery only. It does not change network settings, write files, contact remote systems, test connectivity, modify configuration, or handle credentials.
Requirements
Windows and NetTCPIP
Requires Windows PowerShell 5.1 or PowerShell 7 on Windows and the built-in NetTCPIP module. The script has no parameters and normally runs without administrator rights.

Review output before sharing
Network configuration can contain internal IP addresses, gateways, DNS servers, adapter names, and network-profile information. Review output before copying it into tickets, reports, public posts, or support requests.

First public PowerShell release
Test-KTDNS v1.0.0
Test-KTDNS performs read-only DNS troubleshooting and returns normalized PowerShell objects. It does not change DNS, write files, download content, modify configuration, or handle credentials.
Supported queries
Eight DNS record types
Query A, AAAA, CNAME, MX, NS, SRV, TXT, and PTR records through DNS only, without LLMNR or NetBIOS fallback.
Requirements
Windows PowerShell
Requires Windows PowerShell 5.1 or PowerShell 7 on Windows and the built-in DnsClient module. Ordinary DNS queries do not require administrator rights.

View SHA-256 checksumsFrom single checks to guided cases
The toolkit started as reusable discovery scripts and now includes consolidated triage, reporting helpers, and guided troubleshooting scenarios.
Discovery
Reusable building blocks
Focused scripts answer one question at a time: mailbox details, forwarding, delegates, sign-in data, role assignments, AD replication, DNS behavior, and more.
Triage
One-command snapshots
Consolidated triage tools gather related checks into a single workflow for M365 users, permissions, mail flow, identity security, SharePoint, networks, servers, and domains.
v2.0
Guided troubleshooting
A scenario front door sequences the appropriate read-only checks so the technician can focus on the case instead of remembering every individual command.
Discover first. Understand the state. Change only with intent.
The current library is read-only-first: tenant, domain, Windows, and network scripts are designed for discovery rather than production changes. Local reports or export bundles are created only when explicitly requested. Always confirm authorization, tenant, account, domain, and target before running troubleshooting tools in a customer or production environment.
Release status
Test-KTDNS v1.0.0 is the first reviewed script promoted from the internal toolkit to a public package. Other internal scripts remain unavailable until they complete the same review process.
