Resolving IP address conflicts
To resolve IP address conflicts:
-
For network environments with statically assigned IP addresses, ensure each local host is configured with a unique IP address.
If your computer has a dynamically assigned address, releasing and renewing its IP address can workaround IP address conflicts.
-
Clear the ARP table of the LAN switch
-
Assign a new IP address that has never been used if that option is available. First ping test the IP address before assigning it to confirm its availability.
Resolving TCP/IP stack issues on the virtual machine
To resolve TCP/IP stack issues on the virtual machine:
- Remove and reinstall your virtual network adapter driver.
-
Verify, using the vSphere/ VI Client, that the ethernet adapter is connected and powered:
-
Enable and disable the NIC and ping test.
-
Uninstall VMware Tools and ping test.
-
Connect to host using the vSphere/ VI Client.
-
Turn off the virtual machine.
-
Remove the ethernet adapter.
-
Turn on the virtual machine. TCP/IP is not loaded.
-
Turn off the virtual machine again.
-
Add the ethernet adapter – at this point either auto assign a MAC or manually assign one.
-
Assign a different IP address to eliminate the possibility of duplicate IP and do a ping test.
-
Reinstall VMware Tools and do a ping test.
