Hello,
Thank you for posting in Microsoft Community forum.
Step-by-Step Troubleshooting Guide:
Step 1: Check DNS Configuration
- Verify DNS Settings
Ensure that the DNS configuration on the devices (especially the Windows 11 device) is set up correctly. You can check and change DNS settings as follows:
Open Network and Sharing Center.
Select Change adapter settings.
Right-click on the active network connection (Wi-Fi or Ethernet), and choose Properties.
Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
In the DNS section, enter the following DNS server addresses:
You can use Google DNS (8.8.8.8 and 8.8.4.4) or Cloudflare DNS (1.1.1.1 and 1.0.0.1).
Click OK to save the settings.
- Verify DNS Resolution
Use the command prompt to verify that the domain resolves correctly:
nslookup bg.microsoft.map.fastly.net
If the DNS cannot resolve this domain, try using other DNS servers or check if the DNS server is experiencing issues.
Step 2: Check Network Connection
- Check Wi-Fi Signal Strength
Ensure the Wi-Fi signal strength is adequate. If the signal is weak, try moving closer to the router or use a wired connection.
- Test Wi-Fi and Wired Connection Speeds
Test the speed of both Wi-Fi and wired connections to confirm if network bandwidth is sufficient.
If the Wi-Fi network is overloaded, try using a wired connection temporarily for testing.
- Try Using Wired Connection
If the issue only occurs on Wi-Fi, try connecting the Windows 11 device directly to the router using an Ethernet cable and check if the SQL server connection works properly.
Step 3: Check Fastly Network Service
- Check Fastly Service Status
Visit Fastly's status page to check for any global or regional service outages. If there is an issue, wait for Fastly to resolve it before proceeding.
- Contact Fastly Support
If Fastly's service is operational but the domain still cannot be resolved, contact Fastly support to verify if the domain bg.microsoft.map.fastly.net is properly configured and added to the service.
Step 4: Check Windows 11 Network Settings
- Disable IPv6
In some network configurations, IPv6 can cause issues. Try disabling IPv6:
Open Network and Sharing Center.
Select Change adapter settings.
Right-click on the active network connection, and choose Properties.
- Uncheck Internet Protocol Version 6 (TCP/IPv6), then click OK.
- Disable Windows Firewall or Security Software
Temporarily disable Windows Firewall or any third-party security software to check if they are causing the network connection issues.
- Update Network Drivers
Ensure that the network adapter drivers on Windows 11 are up to date. You can check and update drivers via Device Manager.
Step 5: Consider Delaying Windows 11 Deployment
- Delay Windows 11 Deployment
If the above steps don't resolve the issue, consider delaying the deployment of Windows 11 until the network and domain resolution problems are fixed.
- Complete Tasks Using Wired Network
In the meantime, use a wired connection to complete tasks and avoid the impact of Wi-Fi network issues.
Summary:
Following the steps outlined above will help diagnose and resolve domain resolution and network connectivity issues. Verify DNS settings, check network connections, use Wireshark for analysis, and ensure there are no issues with Fastly services. If the problem persists, consider delaying the Windows 11 deployment and temporarily using a wired connection.
I hope this helps! Let me know if you have further questions or if you need additional assistance.
