+# AD Commands and Scripts
+
+This is a collection of Command Prompt and PowerShell commands and scripts I have collected and built for working in Windows Active Directory environment. Mostly for my own ease of access from anywhere. But I figured might as well release them into the wild.
+
+There's nothing crazy in here (yet). Just some things I didn't want to commit to memory. These assume you have some know how, but not much. I've made READMEs, comments, and other notes where I felt appropriate. But please read and understand each command/script before using. And of course, feel free to tweak to your own needs.

+### Network Reset
+
+Run the following command in an elevated Command Prompt:
+
+```
+ipconfig /flushdns && ipconfig /release && ipconfig /renew && ipconfig /registerdns && netsh winsock reset && shutdown /r
+```
+
+This will, in order:
+1. Flush the DNS Records
+2. Release the IP Address
+3. Renew the IP Address
+4. Re-registers the DNS Records
+5. Resets the Winsock Catalog (requires a reboot after)
+6. Restarts the PC
+
+Be cautious if running these commands while remotely connecting to another computer. The "&&" operator tells CMD to run the commands one after the other. If you run them one at a time instead, you will lose connection to the computer before you can complete the rest. It might be best to have someone on the other end in case you lose connection, or the computer does not regain connection after the restart.
+
+<br>
+
+### SFC & DISM Commands
+
+The following commands will repair/replace corrupted/missing system files, as well as clear up disk space. They must all be ran in an elevated Command Prompt:
+
+1. 
+```
+sfc /scannow
+```
+
+If it reports no issues found or all issues fixed, you are done. or, optionally skip to Step 6. Otherwise, continue to Step 2.
+
+2. 
+```
+DISM /Online /Cleanup-Image /CheckHealth
+```
+
+3. 
+```
+DISM /Online /Cleanup-Image /ScanHealth
+```
+
+4. 
+```
+DISM /Online /Cleanup-Image /RestoreHealth
+```
+
+5. Repeat Step 1
+
+Note: the following optional steps will free up disk space, but also remove files allowing uninstallation of Windows Updates
+
+6. 
+```
+DISM /Online /Cleanup-Image /AnalyzeComponentStore
+```
+
+If prompted to reboot, do so
+
+7. 
+```
+DISM /Online /Cleanup-Image /StartComponentCleanup
+```
+
+8. 
+```
+DISM /Online /Cleanup-Image /StartComponentCleanup /ResetBase

+### Notes
+
+Moving forward, future PowerShell versions no longer support Get-WmiObject. So if all of a sudden you see the error message like “RPC Server is unavailable”, it’s probably time to switch over to Get-CimInstance instead. The parameters are the same for Win32_LogicalDisk. Simply replace Get-WmiObject with Get-CimInstance and you are good to go.
