AppFabric problems with the cache cluster

Hey,

one customer has change the active directory domain. Now the SharePoint runs perfect in the new domain. Only the distribution service will start and stop.

When I check the cache cluster and there is still one host. The host is the old SharePoint server in the old domain. How I can remove the old server from cache cluster and bring the new server as a host in the cluster? Or can I reinstall the complete AppFabric?

 

Thanks for your help
