The cluster network "Partitioned" status usually caused by incorrect network configurations, and the heartbeat packet UDP 3343 unable to send between the two NICs.
Please try to run ipconfig /all on the two nodes, ensure the NICs in the "Partitioned" network are configured with an IP address. Please ensure the NICs on the nodes can ping with each other.
If IP settings are well, please check if there's any firewall between the nodes, if yes, please try to turn off the firewall, try to re-enable the NIC and update the network adapter driver, check if the methods could help.
Thanks for your time!
