Sembra essere qualcosa di collegato ai security setting di IE.

Soluzione:
Editare il file install.ins inside: {GUID of Policy}\user\MICROSOFT\IEAK

Chiudere e riaprire GPMC e il problema è risolto.

Sintomi:
Quando tenti di accedere alla cartella Cluster Shared Storage in C Drive dal nodo passivo il sistema va in hang ed explorer si blocca,mentre il nodo attivo riesce ad accedere al CSV storage senza nessun problema.

Errori riportati a livello event viewer:

Cluster Shared Volume is no longer available on this node because of “Status_Bad_Network_Path”. All I/O will temporarily be queued until a path to the volume is reestablished.
