From a Windows 2008 R1 SP2 environment where Failover Clustering is installed and setup, I could not ping any WINS record but could ping on any other Windows environment. The workaround is to provide FQDN but trying to figure out why this is only happening on a clustered environment. Network settings are the same for all the servers(of course except for IP address). I have not tested this on Windows 2008 R2 on a clustered environment but it works fine without clustered installed. Thanks in advanced, Joel

The fact that its clustered shouldnt have any effect. Check the WINS clients configuration on the clustered nodes and verify that they are correct. Visit: anITKB.com, an IT Knowledge Base.

Hi, In addition, please also temporarily disable firewall to test the issue. For more troubleshooting information, please also refer to the following Microsoft KB and TechNet articles: How To Diagnose and Test TCP/IP or NetBIOS Network Connections in Windows 2000 http://support.microsoft.com/kb/300986 Troubleshooting WINS http://technet.microsoft.com/en-us/library/cc959203.aspx Regards, Arthur Li TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com .

Hi Arthur, We might have narrowed it down to VLAN ID within HP Teamed network. It happened to be that all our clusters are running Windows 2008 and are blade servers. Thanks again for the support. Regards, Joel
