The lab below is not working for me.
Exercise 2: Troubleshooting IPv4
u Task 1: Prepare for troubleshooting
- On LON‑SVR2, on the taskbar, click the Windows PowerShell<sup>®</sup> icon.
- At the Windows PowerShell prompt, typeping LON‑DC1, and then press Enter.
- Open a Windows<sup>®</sup> Explorer window, and browse to\\LON‑DC1\E$\Labfiles\Mod05.
- Right‑clickBreak.ps1 (change the LAN in script to your Ethernet card), and then clickRun with PowerShell. (I edited this first to match with my network card)
- Close Windows Explorer.
u Task 2: Troubleshoot IPv4 connectivity between LON‑SVR2 and LON‑DC1
- On LON‑SVR2,
at the Windows PowerShell prompt, type ping LON‑DC1,
and then press Enter. Notice that the destination host is unreachable. (I can still ping. This is where my issue is.)
- Typetracert LON‑DC1, and then press Enter. Notice that the host is unable to find the default gateway, and that it is not the default gateway that is responding back.
- Typeipconfig, and then press Enter. Notice that the default gateway is configured correctly.
- Typeping10.10.0.1, and then press Enter. Notice that the default gateway is responding, but that packets are not being routed there.
- TypeGet‑NetRoute, and then press Enter. Notice that the entry for the default gateway (0.0.0.0) is correct, but there is an unnecessary entry for the 172.16.0.0 network.
- TypeRemove‑NetRoute –DestinationPrefix 172.16.0.0/16, and then press Enter. This removes the unnecessary route to the 172.16.0.0 network. The default gateway will be used for routing instead.
- PressY, and then press Enter to confirm removal of the route from active routes.
- Typeping LON‑DC1, and then press Enter. Notice that the ping is now successful.
If I remove the default entries on the routing table and then create entries again with appropriate IP numbers, then No. 2 on Task 2 doesn't work.
It would be great if someone who already has a workaround for this.
