Hi,

Now i need two virtual ip's for installing sap, sap installer will use these ip's and create 2 services and application automatically. Now  suppose i have 2 ips which is not used anywhere and start installing with those ip's installation couldn't start stated me to view sap note  1564275 proceed accordingly. As per the note we have to enter these 2 virtual ip in network adapter and it will be viewed via ipconfig and alter some registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters

Add the value BackConnectionHostnames:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0

after this we have to try net view\\virtual hostname

I have added virtual ip in network adapter which contain physical ip of node which is used in failover cluster when i have added this virtual ip in adapter then the ip which is used in cluster manager gets changed to ip which is added last in network adapter.

Kindly assist how to configure virtual ip in windows failover clustering for sap again we are not using any virtual environment hyper-v, vmware...
