KB: Networking errors (23801, 23753) when a virtual machine is assigned a static IPv4 address through System Center 2012 R2 Virtual Machine Manager

 When you use System Center 2012 R2 Virtual Machine Manager to migrate a virtual machine, the job is completed successfully but one or both of the following errors are returned in the job result information:

Error (23801)
No available connection to selected VM Network can be found.
Recommended Action
Ensure host NICs have connection to the fabric network on which VM Network is created.

Error (23753)
The virtual machine or tier load balancer configuration requires an IP pool and there are no appropriate IP pools accessible from the host.
Recommended Action
Select a host with access to an appropriate IP pool and try the operation again.

This issue occurs if the virtual machine’s virtual network adapter is connected to a virtual machine network that does not have a static IP address pool defined for it. Additionally, the IPv4 address type was changed from dynamic to static by going inside the virtual machine and manually changing the IP address configuration.

For all the details and a resolution, please see the following:
