Cause of the issue:
The admin share for the servers was disabled. Admin shares are a pre-requisite for the Installation of clustered SQL instance. We manually created the admin shares for both the nodes and did a restart of both the nodes and setup failed in the same step. We checked and found that the admin shares were disabled. On every restart the admin shares were getting disabled.
We went to this registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters and checked the values of these keys AutoShareServer and AutoShareWks .
They were configured with a value data of 0, changed that value to 1. Now we did a restart and the admin shares were still there. We were able to complete the installation.
We have a KB article on how to enable admin shares http://support.microsoft.com/kb/245117
