We used windows 2003 R2 cluster with two nodes. Recently both the servers crashed due to some reasons!

So below was the steps I tried to recover the system:

  1. I install the same OS (2003 R2 enterprise) on both server
  2. Restore the all data including system status using NTBACKUP tool.

Everything is OK ! After logging in to both system, the cluster services can't be started.

I want to know anything need to pay attention when restoring the cluster node?

Thanks.

A system state backup is not enough to restore a failover cluster:

The standard solution would be to evict the failed node from the cluster and then re-add it; but since both nodes failed in your case, you'll probably have to destroy the cluster and re-create it from scratch, if you don't have all you need to restore it (see the two articles I linked above).
