because I keep the servers in a different subnet/vlan than the clients

It's registered in the lease with the "set ClientIP" and "set 
ClientName" in the "on commit" clause

I knew you would ask ;-)
Because up until a few weeks ago we had a netapp filer where there was a 
share for software installation (via domain policies) *but* the client 
machines had endless problems accessing that share with the machine account.
OTOH no client had problem accessing sysvol on the dc.
I kept those shares so I could easily copy the software to install and 
nfs mount that same directory on the DCs and symlink it inside sysvol.
Now we don't use netapp anymore (good riddance!) but I still keep the 
same layout: if it ain't broke don't fix it ;-)

Bye
