Kiwi Si After imaging a server and then trying to add it to a Windows Server 2003 Network Load Balancing (NLB) configuration with the original machine you will get this error message: “no interfaces are available for installing a new cluster”.
This is due to the network GUID’s in the registry being the same. Even re-SID’ing the server using a product such as SysInternals ‘newsid’ does not resolve this issue. Do not fear – it is infact easy to resolve. What you want to do is give the network adapter that you’re trying to add to the network load balanced configuration a new GUID.
Follow these steps:
1. On the server from the image enter into ‘Device Manager’.
2.Expand out ‘Network Adapters’ and right mouse click on the Network adapter that you are trying to add to the network load balanced (NLB) configuration.
3. Select ‘Uninstall’. The network card (NIC) has now been uninstalled.
4. Next you want to re-add the network card which in turn will create a new GUID for it. Do this by right mouse clicking your servers name at the top of the ‘Device Manager’ list and select ‘Scan for hardware changes’. This will now re-detect the network card (NIC) and give it a new GUID.
5. Now exit out of ‘Device Manager’ and try re-adding that server into the NLB configuration. You should find this now works all ok.
Good Luck
