Network adaptor unavailable
Hi All,
After upgrading a cluster server from windows 2008 R1 to windows 2008 R2 the server cannot connect to the network anymore.
The adaptor is still there and the heartbeats are working , but the principal network cannot be reached.
The server is an HP and the veritas cluster software is 5.1 SP2.
Any suggestions how to fix ?
Since the portal from Symantec is unavailable to log a case , i need some help ?
Hi Blizzie,
It sounds like you maybe hitting a basic Windows 2008 R2 network security issue and not a problem with SFW-HA configuration. Windows 2008 R2 adds some security fixes and enhancements to the server when installed. It may have enabled the Windows Firewall or restricted it to the point clients are not able to connect to the server again.
Check to make sure that basic Windows TCP/IP connectivity is working as expected. If you are able to go out from the server other network resources and connect to these servers from a client, then check to make sure that the NIC configuration is still as expected and that he MAC address has not changed for the public NIC.
Thank you,
Wally
