well the clusterware installation still brings an error

OUI-35006: Error while copying the file 'C:\windows\system32\drivers\orafendedrv.sys' within the folder 'C:\windows\system32\drivers' on node 'ILL_SRAC2'. [PRKC-1080: File "C:\windows\system32\drivers\orafencedrv.sys" could not be transfered to given node "ILL_SRAC2". Error on node ILL_SRAC2:null]

before I
pinged all 3 ip's from both nodes
net use on both nodes
runcluvfy on node1 --> no errors

I was installing as local administrator and both nodes have the same password. Interesting is that there is no problem copying to oracle home (\crs).

Any ideas about this?
