Hostname Resolution Failed - Windows Cluster Client
Hi all - I am having a problem with a Windows cluster client not backing up - here is the background info:
Networker 7.6 SP1 server running on Linux
Networker 7.6 SP1 client running on 2 Windows 2008 server cluster nodes, local filesystem backups working fine
Cluster client set up in Networker client with name of Windows cluster
Daily backups of cluster client fail with "hostname resolution failed"
I putty'd into the networker server and was able to do an nslookup for the cluster name and was able to ping the name with or without the FQDN
I have other Windows cluster backups set up and working fine (they are 2003 clusters, but it should be the same set up) - any ideas? Thanks!
John

I found the issue for this - there was no PTR record for the cluster name, so even though I could resolve the hostname with a forward lookup, I couldn't with a reverse lookup. Once I added a PTR record for the cluster name, it worked fine. Thanks!

Make sure you have created client name with short name. (dont use FQDN for cluster client)
Make sure you have added short name, all FQDNs in the alise list of client configuration. Also add ipadress of the virtual client in the aliase list.
Try a client side backup,
From your desktop connect to virtual client using remote desktop (mstsc).
Go to Start > run > winworkr.
Select any file or folder which you see under the virtual client and run backup. See if it works fine.
