PHASPDC
aka ALICE is a domain controller (Active Directory) running
Microsoft Windows 2003 Server Standard Edition. ALICE responds to any
authentication requests within the PHAS Windows Server domain.
Active Directory replication takes place between domain controllers -
in our case, ALICE and WHITERABBIT.
Active Directory uses a multimaster model, which means changes can be
made on any domain controller and the changes are sent to all other
domain controllers. See http://www.comptechdoc.org/os/windows/win2k/win2kadrepl.html, for more information on Active Directory replication.
In order for Active Directory to function properly, DNS servers
must provide support for Service Location (SRV) resource records
described in RFC 2052,
A DNS RR for specifying the location of services (DNS SRV). SRV
resource records map the name of a service to the name of a server
offering that service. Active Directory clients and domain
controllers use SRV records to determine the IP addresses of domain
controllers. See What DNS entries (SRV Records) does Windows 2000/2003 add when you create a domain?.
Roaming Profile is utilized to preserve Windows users settings.
Furthermore, ALICE provides centralized computing (Terminal Server) for Neoware thin clients in Hebb 30.
