Adding disc

[BGoggins@xxxxxxxxxxx]

We have a domino server (windows) outside our firewall that replicates 
with our iSeries  server.  It  is running out of space, but we don't want 
to go through adding all the security we put on our current server.  Can 
we set up a windows server with lots of disc and map it as a drive on our 
current server?  Is there a better way to add space without having to 
rebuild our current box? 

Also, is there a group like this for windows issues?  TIA    Bob
