Have a MS Cluster solution at a client, inherited did not set it up.
Have a Hyper-V machine (2008 Server as a file server) running on the cluster.
When I RDP or connect to the Hyper-V machine, via 10.0.0.8 it works fine all is well.
Yesterday, this server had a second network interface 10.0.0.7, today it is gone.
I didn't touch it, not sure where it went, but I need to recreate it and I don't know how.
Need some help.
