Re: Long failover time...

Really? Hmmm. I've seen 90% of long failover times resolved by doing this.

Hosts file! No, DNS works nicely :)

I thought it was recommended to put all cluster names/ips in the hosts file located at:
%WINDIR%\system32\drivers\etc\hosts

By default, you don't want your cluster communicating over the public (client access) interface and you don't want your cluster to fail just because your DNS server goes down or is not accessible.

By adding each node to this file on both nodes, you won't even do a name lookup via DNS since Windows uses hosts/lmhosts then DNS.

Thanks and I appretiate your reply...

Is it required to create a PTR record for the Cluster Name in the DNS
Server??? We already have a cluster whose name is registered in the DNS only
for forward lookup...

Thanks.

Looks like problems contacting an authoratative DNS server for the reverse
lookup zone that holds the PTR record.
