I have seen this problem to occur after a Storage vmotion, Try these options and one of them should work for you.
Option 1
Go to Edit Settings in the affected virtual machine and disconnect the vNIC.
Use vMotion to migrate the affected virtual machine to another host.
Reconnect the vNIC after the vMotion operation has successfully completed.
Option 2
Replace the vNIC on the virtual machine:
Obtain the correct network information for the vNIC, such as Static IP, Subnet Mask, VLAN, and the dvPortGroup information.
Shut down the guest virtual machine that reports the error.
Remove the vNIC.
Add a new vNIC and populate it with the information noted in step 1, such as Static IP, Subnet Mask, and VLAN.
