

Running one “machine” inside another “machine”
OS in Virtual machines sees
◦
◦
◦
◦
◦


CPU(s)
Memory
Disk
USB
etc
Disk is really a file on “host”
Memory is usually part of “host’s” physical
memory
◦ Only have so much so need to allocate sparingly

Para-virtualization
◦
◦
◦
◦
◦

Guest OS “Knows” it is virtualized
Changes some of the function calls for hardware
FAST!
Guest OS must be modified
xen uses para-virtualization
Full virtualization
◦
◦
◦
◦
All details of virtual environment hidden
Guest OS unchanged
Time overhead!
VMWare and VirtualPC use full virtualization

Host-Only
◦ Network internal to host
◦ Guest OS can’t get out!!!
◦ Nice for testing

NAT
◦ Network internal to host
◦ Host NIC acts as NAT router (like RRAS)
 Substitutes own IP as source address as sends out
◦ Nice for testing
◦ More work for host
◦ Double- (Triple-) NAT can cause some issues

Bridged Networking
◦
◦
◦
◦
Guest NICs all plugged into virtual bridge/switch
Each has own MAC address
Bridge keeps track of which MAC is which
Packet comes in
 Hits Host NIC (only real connection out)
 Bridge software looks in bridging table for that MAC
 “Sends” to that virtual NIC

From outside, it looks like Host has multiple
NICs, MACs, and IP addresses
◦ E.g., each Vhost “looks” like a real machine

Cost
◦ Cheaper to have one BIG machine than several smaller
ones

Green
◦ Less electricity used

Recovery
◦ Hardware fails, move Vhost files to other server and
start!

Snapshot recovery
◦ Roll it back

Need 32-bit OS but all have is 64-bit servers
implemented


Microsoft’s email system
Supports
◦
◦
◦
◦
◦
Outlook
SMTP
Webmail
Filtering (Spam)
etc

Windows 2003 32-bit

Active Directory


◦ 64-bit OS not supported
◦ Ideally Exchange not on DC but can work for testing
Patch OS
Install
◦ Application Server
 ASP.NET
 IIS
 NNTP & SMTP
◦ Server 2003 Support Tools
 D:\English\WindowsServer2003R2withSP2VLP\Enterprise\
32bit\SUPPORT\TOOLS\SupTools.msi





Run DCDiag
Run NetDiag
Run ForestPrep
Run DomainPrep
Install Exchange

dcdiag /f:c:\dcdiaglog.txt
/s:domaincontrollername.domain.com
◦ /f:file # put output in this file
◦ /s:DC # talk to this domain controller

Checks to make sure Active Directory is
healthy and you can communicate with it.

Netdiag >c:\netdiaglog.txt

Checks out network config
◦ IP address
◦ domain membership
◦ etc

Fix any errors that come up

Run off Exchange deployment wizard
◦ or `setup /forestprep`

Must be logged on as
◦ Forest-wide Administrator
◦ Schema Administrator
◦ Local Administrator

Changes AD Schema (rules)
◦ New classes; New Attributes
◦ Creates “MS Exchange System Object” container in
domain
◦ Allows specified account full Exchange permissions

Run off Exchange deployment wizard
◦ or `setup /domainprep`

Must be logged on as
◦ Domain Administrator
◦ Local Administrator

Creates two domain groups
◦ Exchange Domain Servers (GG)
 All exchange servers in the domain
◦ Exchange Enterprise Servers (DLG)
 ExchangeDomainServers groups from all domains


In wizard, click “Run Setup Now”
Component Selection
◦ CONSIDER moving install path to different disk
◦ MUCH more efficient if Exchange not on OS disk



Give you organization a name
Accept summary
Finish install

Disable Unwanted Services (via services.msc)
◦ IMAP, POP3, NNTP, SMTP?

Setup Routing Connectors (opt)
◦
◦
◦
◦
Sort of like Sites and Site-Links in AD
Govern which exchange server can talk to which
Connectors link the routing groups
Bridge head server in each Group
 Non-bridge head servers send to local bridge-head
 Bridge-head communicate between the groups

Setup Policies

AdminGroup > Servers > server > Storage
group >
◦ props of Mailbox store
◦ Set Mailbox limits and deletion settings

AdminGroup > Servers > publicStore
◦ props of Public store
◦ Set store limits and deletion settings

Can create a policy to do this globally


AdminGrps > FirstAdminGrp > RoutingGroups >
FirstRoutingGrp > Connectors >
Create New Connector > SMTP
◦ Give it a name

Specify Bridgehead Server
◦ Send/Receive Internet mail

Address Space
◦ Add SMTP and leave defaults (can send/receive
to/from any address)


AdminGrps > FirstAdminGrp > Servers> Server>
Protocols > SMTP
Create New SMTP Virtual Server
◦ Give it a name
◦ Pick IP (or all)


Limit Message Sizes, # recipients, etc
Relays (BAAaaad – turn them off!)

Need a client
◦ Outlook – comes with MS Office
 We’ll do this later!
◦ Web client

Check props of user(s)
◦ Enable Web access
 Rclick user > Exchange Tasks > Configure Features
 Outlook Web Access should be enabled

On client
◦ http://server/exchange


Stay Tuned!
