SWARM fails to connect after domain controller fail

Hello,
I have currently inherited a new client who has recently recovered from a failed Domain Controller. However it appears something has changed between the last DC and the new DC. Our client has asked us to angage and look into how to make SWARM ‘work’ again after the DC has changed.

Currently when I look at SWARM - I see it has a a D: for cache and an IP address for Coordinator, however tat IP address is not an IP I am aware off since the DC change.

What I am currently seeking is a guide on how to make SWARM work again, IE does it need to be reinstalled to a server and the workstations need the correct IP or is there another factor that is required to have the workstations connects again. I have included the log below from one of the PCs in the office;
