SEP client loss communication with SEPM

Recently our SEP server hardisk have gone failure and it's located inside the virtual machine. We unable to retrive the vhd file or any database backup and server certificate. So we reinstall SEPM into new server. Can we get all the client to connect back with the SEPM server again? We have use same server name and ip address. We cannot import sylink file into each client since we have hundreds of SEP clients. Any way? Perhaps can generate server certificate somehow.
