The cluster generation fails at the OS Level. We've got 2 servers with Windows Server 2008 R2 Enterprise 64Bit. When I want to create the cluster in failover cluster manager, it comes until the point "forming cluster". Here it hangs an comes after 2 minutes up with a timeout. The prevalidation is 100% free of errors. If I take a look at the clusterlog, I see this "Security Handshake failed to obtain SecurityContext for NetFT driver". Node 2 forcibly closes the connection so the cluster creation fails.

Tell me whatever further details you need!
