IT:Network:Applications Fall 2009

 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 system  Supports ◦ Outlook ◦ SMTP ◦ Webmail ◦ Filtering (Spam) ◦ etc

 Windows bit ◦ 64-bit OS not supported  Active Directory ◦ 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 ◦

 Stay Tuned!  More next week
