Possible Cause: The Volume Shadow Copy Service is unable to allocate disk space to create a shadow copy because the maximum size of the shadow storage area is too small.

Solution: Increase the shadow copy storage area for the volume listed in the error event, or set the maximum size to “No limit” by following these steps:

1. Right click any volume and choose Configure Shadow Copies.
2. With the Shadow Copies utility open, select the volume with insufficient space;
3. Click Settings…
4. In the “Maximum size” box, either increase the limit, or choose “No limit”.

1. Export from DomainA:

csvde -f C:\Rename\export_AD.csv -m -n -o “primaryGroupID,lockoutTime” -j C:\Rename\Logs

Where:

-f filename to export to

-m do not export SAM values, e.g. objectSID

-n do not export binary values

-o exclude named columns

-j folder to log to (produces csv.log, plus csv.err if any errors occured)

2. Edit the export_AD.csv file as follows:

Delete the lines beginning:

o   “CN=Builtin …       (1 expected)

o   “CN=Infrastructure… (1 expected)

Delete all lines containing:

o   ,samServer,     (1 expected)

o   ,rIDSet,           (1 expected)

o   ,secret,           (4 expected)

o   ,rIDManager,       (1 expected)

Remove any ‘box’ (ASCII 13) characters in the text:

o   Unfortunately these cannot be searched for in Notepad

o   There may be one in the commas at the end of each of the last 50 lines in the file

Replace all instances of ‘PCOld’ with ‘PCNew’

o   Where PCOld is part of the machine name and domainname

3. Import into DomainB:

csvde -i -f C:\Rename\export_AD.csv -k -j C:\Rename\Logs

o   -i import

o   -f filename to export to

o   -k ignore non-serious errors (e.g. object, attribute or value already exists)

o   -j folder to log to (produces csv.log, plus csv.err if any errors occured)

1. With Palo open, go to Network >Interface > Tunnel,  click Add to create a new tunnel interface and enter the following info:
   Name: tunnel.1

Comment: Chicagotech VPN or any comment.
Virtual router: Default or any existing virtual router you have.
Security Zone: DMZ (It must be the layer 3 internal zone from which the traffic will originate)2. Go to Network > Network Profiles > IKE Crypto , click Add and enter the IKE Crypto profile (IKEv1 Phase-1) parameters. These parameters should match on the other site firewall for the IKE Phase-1 negotiation to be successful.

3. Go to Network > Network Profiles > IKE Gateway to configure the IKE Phase-1 Gateway. There are 3 options for the Version where you can select IKEv1 only mode, IKEv2 only mode or IKEv2 preferred mode. Two sites must use the same mode, for example IKEv2 preferred mode. Enter al other info.

4. Under Network > Network Profiles > IPSec Crypto , click Add to create a new Profile, define the IPSec Crypto profile to specify protocols and algorithms for identification, authentication, and encryption in VPN tunnels based on IPSec SA negotiation (IKEv1 Phase-2). These parameters should match on the remote firewall for the IKE Phase-2 negotiation to be successful.

5. Under Network > IPSec Tunnels, click Add to create a new IPSec Tunnel. In the General window use the Tunnel Interface, the IKE Gateway and IPSec Crypto Profile from above to set up the parameters to establish IPSec VPN tunnels between firewalls.

6. When configuring an IPSec Tunnel Proxy-ID configuration to identify local and remote IP networks for traffic that is NATed, the Proxy-ID configuration for the IPSec Tunnel must be configured with the Post-NAT IP network information, because the Proxy-ID information defines the networks that will be allowed through the tunnel on both sides for the IPSec configuration.

7. Under Network > Virtual Routers, click on your Virtual router profile, then click Static Routes, add a new route for the network that is behind the other VPN endpoint. Be sure to use the proper Tunnel Interface. Click OK when done.

8. Save all settings.

To turn on location services and enable location permissions for the Google Home app, please follow these steps:

1. Tap Settings on the phone.
2. Tap Apps & notifications.
3. Tap home

4. Tap Permission Location and enable it.

Or 1. Tap Settings.

2. Tap Security & Location.

3. Tap Location > Turn on location.

1. Can’t find Chromecast devices when trying to link devices to Google Home because some devices such as Roku products, Apple TV products, and Amazon Fire TV products.
2. Smart TVs works with windows WiDi, but not Chromecast because that aren’t Android TV devices or TVs with Chromecast built-in.
3. Make sure the Chromecast device is powered on.
4. Make sure all devices such as TV, PC, Mac, Labtel, phone are connected to the same Wi-Fi network.
5. Make sure location services is on and location permissions is enbled for the Google Home app and phone.
6. Make sure your firewall or security software doesn’t block chromecast.

Situation: The client has Windows 10 laptop, which can use Windows Wireless Display. However, Chrome cast can’t find Roku TV. Note: New Roku supports Miracast.

Troubleshooting: 1. Based on our search, Roku products, Apple TV products, and Amazon Fire TV products aren’t using Cast technology and therefore can’t be linked to Google Home. Note: New Roku supports Miracast.

2. Update your WiFi, router,  Roku firmware.

3. Try to Enable/Disable Quality of Service (QoS) to see if that fix the problem.

4. Reset all devices: Most connectivity issues can be remedied by simultaneously restarting the ROKU device as well as the Router. You might have Roku WiFi issues during the show or movie that you’re watching stops suddenly, usually with a message such as, for example, “connecting” or “transferring.” You may also observe a message that says Roku has lost its WiFi connection. This may happen even if your Roku says it has a strong signal from your WiFi router.
In such situation rebooting the Roku can briefly resolve the issue, however if it continues returning, it is better to change the WiFi router or you can buy a new cable modem

5. Disable the train wreck that is wifi interference mitigation which causes the Roku to try to drown out nearby wifi sources. Here is how1) Start up the Roku and get to the home screen.

1)  Start up the Roku and get to the home screen.

2) Press these 10 buttons quickly: HOME-HOME-HOME-HOME-HOME-FFWD-PLAY-REWIND-PLAY-FFWD

3) Select “Wireless Secret Screen” from the menu choices

4) Select “Interference” from the menu choices.

5) Choose “None”

6.  Change Roku TV settings: I went into the Roku stick settings and changed the tv to 720. No more buffering.

7. Change WiFi channel: There is a free Windows program, WifiInfoView, which can be downloaded and run and will show all kinds of information about the wifi networks in your immediate area. Change your wifi channel to one that none of your neighbors are using. This will help both video and remote signals.

8.  Change MTU settings: This made a very noticeable improvement in my PCs network performance (changed from the default 1500 to 1492 for ATT dsl). Either my Roku 3 sets it automatically (certainly possible) or it doesn’t and my streaming performance is degraded.

9. Also check any other software and computers that may be processing your video. For example, I got much better performance by changing my PlayOn software Video Performance setting from Auto to Medium. A fast computer also helps if the computer is doing video conversion while streaming.

10. Check for wireless interference: Cordless phones, microwave ovens, or other wireless devices near your router can all cause wireless interference, so move them away from your wireless router.

11. Check any anti-virus or security software blocking the traffics.

To configure Chromecast, please use the Google Home app that will help you to set up your Chromecast device. This includes Chromecast, wecast and Chromecast Ultra.

Before we begin, please make sure you’re using the latest version of Chrome by navigating to “Settings > About Google Chrome” and update your Chrome browser to the latest version, if necessary.

1. Navigate to chromecast.com/setup from the Chrome browser on your computer.
   Click “Set up your Chromecast using this computer”.

2. Chrome looks for Chromecast devices that need to be set up.
Click the device that matches the Chromecast name you see on your TV. It will be something like ChromecastXXXX. Click Set Me Up.
Read Privacy & Terms > Accept.
Setup will try to automatically connect to the Wi-Fi hotspot produced by your Chromecast device. If this is successful, move to step 8.
If this isn’t successful, you need to manually connect to the Wi-Fi hotspot of your Chromecast device.
Go to your Wi-Fi menu and select the Wi-Fi network that matches your Chromecast device name.
Connect to the network. Important: Make sure you’ve successfully connected to the Wi-Fi hotspot before moving to the next step. This can take a few minutes. Note: You’ll lose your Internet connection for few minutes until setup is complete. This is expected.
Click Next.
The code on your device should match the code on your TV. If it does, click Yes.
​If it doesn’t match, click No and restart the setup process from step 5 above.
Change the name of your Chromecast by typing in a new name (ex. Living Room) or you can leave it as the default name. Choose your country. Click Looks Good.
Choose your Wi-Fi network by clicking the upside down arrow. Enter your password. Click Connect.
Setup will try to automatically connect to your Wi-Fi network. If this is successful, move to step 13.
If this is not successful, go back to your Wi-Fi menu and choose the same Wi-Fi network you picked in step 10.
Important: Make sure you’ve successfully connected to the Wi-Fi network before moving on to the next step. This can take a few minutes.
Click Next.
Once setup has successfully completed, you’ll see a list of all of your available Cast devices.
Your Chromecast is now ready to cast. You can cast from your favorite Chromecast cast-enabled mobile app or cast a tab from the Chrome browser on your computer.
Download the Google Home app to get the most out of your Chromecast.

Before you configure a device to use Wecast Wireless Display, you’ll need:

Chromecast/Wecast or Android TV
The newest version of Chrome OS. Learn how to update your Chromebook software.
A TV with HDMI input

This example is based on Wecast Wireless Display Dongle. Wecast Wireless Display Dongle can be used to cast from the small screen of most Android, Windows, ISO devices to big screen.

Here is how.

1. Connect Wechast to TV with selected HDMI and USB.

2. On the device (PC, Mac, Tablet, Phone), go to WiFi settings. Select Wecast-xxxxxx, enter the default password 12345678, and connect.

3. Open a Brower, enter Wecast default IP address 192.168.49.1. It will show WiFi and Settings. Click on WiFi.

4. Now, you have two options: Scan and Add network. Click on Scan. That will show all available wireless.

5. Now, make sure all your devices (wecast, TV and PC/Phone) are connecting to the same WiFi. On the device (Android phone in our example), go to Settings>Connected devices.

6. Tap Connected devices, then Cast.

7. It may take a few seconds to connect to Wecast.

8. Now open Chromecast or Chrome Home

9. Connect to Wecast and the TV will show the remote device screen.

In PC you may have two options to connect the PC to TV screen. I) Go to Display and then select Wireless display. 2) Click Connection icon in the low right corner and then select Connect.

Situation: One of network computers lost the Internet connection. The computer can still access to all network resources but the Internet. It can’t ping the Cisco ASA firewall and any public IP addresses. The ASA can’t ping the host. This is the contention: Internet—ASA—Switch—SonicWall—Switch—Host.

The SonicWal and the host can ping each other. SonicWall can see host arp table but ASA can’t.

Flush the host arp table on SonicWall fixes the problem.
