Hi there,

my server (BDC) got the error
event id : 201
source : License Service
Description : No license was available for user server\username using
product SMB server 4.0

I have done according to Microsoft support but can't solve the problem. I
intended to reinstall winnt, how can I maintain the permission setting for
each folder, so that after I reinstall the permission is still remain in
each folder ??? Please help !

Thanks
