Thanks for the replay
The answers to the 2 questions are yes as you have said.
This is my configuration

Group1
    CLuster IP
    Cluster Name
    Cluster Quorum Disk

Group2
    SQL Network Name
    SQL IP
    SQL Disks
    SQL Server (instance) with agent and so on..

Group3
    SQL Network Name
    SQL IP
    SQL Disks
    SQL Server (main) with agent and so on..

Group4 (Created for BackUp reasons)
    NetworkName
    Disk
    IP

Group5 (Created for BackUp reasons)
    NetworkName
    Disk
    IP

And i have created in Group2 let's say a new resource "FileShare"
I give permisions to access this resource and write on it, on the machines
Web1 & Web2

So now I try to access the disks from web1 & web2 and a get an error (A Part
of the path could not be resolved)
I map the share on the web1 & web2 let's say with drive letter Y:\ and I
also get the same error
I Try to access the share not with the network name of the group but with
the Node name and everything works.

That's all i have tried.
You are suggesting to enable Kerberos on the network name??
I'll try it and I'll get back on you
