OS Level Anti-Virus Scanning Exclusions for Exchange Servers

In this article we will discuss about how to exclude the File Level Anti-virus scanning on a Exchange server 2010

 

File Level Anti-Virus Scanning some times cause you problem with Applications, So better way to Exclude some of the Files which used by application.

 

If they are not correctly configured it might cause problems for Exchange 2010.

 

Let’s discuss how we can Exclude the files from our Anti-Virus scanning for several Exchange services.

 

As per recommendation from Microsoft, Exchange Databases, Logs Files, Extensions and other related directories will be excluded from AV Scanning.

 

Directory Exclusion Sub-Directory Exclusion
C:\Windows\System32\Inetsrv All
E:\Program Files\Microsoft\Exchange Server\V14\Mailbox All

E:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs

All

Configure Client Access Server Array Exchange 2010 using WNLB

In this blog im going to configure client access server array, Previously MAPI Clients used to connect to direct Mailbox Server. But with Microsoft Exchange 2010 all the MAPI Users are now connected to Client Access Server.

Every Mailbox database is associated with Client Access Server service called RPC Client Access

Microsoft Recommends for CAS array Load Balancing with WNLB or Hardware NLB.

Note: You cannot do WNLB with DAG Failover cluster  on the same server

As you can refer the following KB article

http://support.microsoft.com/kb/235305

http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/91050612-a602-4a4e-af23-9ffc33dccdde/

We have option to use either WNLB or Hardware Load Balancers. In this scenario im going to configure CAS Server with Windows Network Load balancing Feature in Windows 2008 R2.

Actually Windows Network Load Balance come with the OS so its very reasonable and easy to configure, It can be a good solution for mid-sized companies wanting a cheap load balancing solution.

Before we start the WNLB we should make sure the IP settings in the server

Each Cas server should have minimum 2 Network Connections connected to LAN,

Configure the network adapter with Static Ips

 

Next Step to install and configure WNLB.

  1. Add the roles from Server Manager WNLB

Now we need to create the cluster in WNLB.

Create New Cluster

 

In New cluster wizard we need to enter the Cluster name , In host section we need to enter the ip of our Exchange Client access server node 1 click connect , The network adapters will be displayed select NLB adapter next.

 

Note: Priority value should be configured as 1 for the first Exchange server member

Same settings we need to configure for Second Exchange server to add NLB adapter as 2 priority.

Enter the Full Server Name:  for Ex : outlook.myexchangeserver.com

Note: This is Virtual Name where all outlook users are going to connect to use since we have created FQDN for CAS array

 Cluster operation mode:

Unicast mode

The unicast mode changes the cluster adapter’s MAC address to the cluster MAC address. This cluster address is the same MAC address that is used on all cluster hosts. When this change is made, clients can no longer address the cluster adapters by their original MAC addresses.

 Multicast mode

When using multicast mode, NLB will add a multicast MAC access to the cluster adapters on all of the cluster hosts. At the same time, the cluster adapters retain their original MAC addresses. This way each host could be addressed individually

By using the multicast method with Internet Group Membership Protocol (IGMP), you can limit switch flooding, if the switch supports IGMP snooping. IGMP snooping allows the switch to examine the contents of multicast packets and associate a port with a multicast address. Without IGMP snooping, switches might require additional configuration to tell the switch which ports to use for the multicast traffic. Otherwise, switch flooding occurs, as with the unicast method.

For more info you can refer TechNet

http://technet.microsoft.com/en-us/library/cc782694(WS.10).aspx

Well, a best practice recommendation is to install two network adapters and use unicast mode, so that the host and cluster network traffic are separated on their own respective network interface. However, if you only have the option of installing one NIC in each CAS server or if you’re forced to using multi-cast mode because of the switches used in your organization, you should pick multicast mode.

Next step

Default  Settings for Ports rules,

 

To improve the security we should edit port and rules for certain protocols to allow access to Client access server.

http://technet.microsoft.com/en-us/library/bb331973.aspx

Once we are done we need to add the host machines in the existing cluster.

Imp Note : By Default windows 2008 disable Ip forwarding so it will cause problem for WNLB we can enable by using

Refer this article for enabling the IP forwaring.

http://kb.matthewtrotter.com/index.php/article/enable-ipforwarding-on-windows-20082008-r2-nlb-clusters

netsh interface ipv4 set interface “NLB” forwarding=enabled

 

Now lets Create CAS Array

Once we are done with the MS Exchange 2010 CAS setup we need to create CAS Array in order to make it one.

First Step.

Open the Exchange Management Shell for creating cas array

Run below Cmdlet

New-ClientAccessArray -Name CASArray -FQDN “outlook.myexchangeserver.com” -Site “Default-First-Site-Name”

Name Parameter Specify the Client access Array name

Site Parameter Specify the active directory site which belongs to Client access server

Note  : After the Client Access array has been created, you’ll also need to create the address in DNS and associate it with the virtual IP address used for the Client Access array.

Once we are done we need to associate RPCClientAccessServer with Mailbox database on which clients will connect

Using CmdLets

Adding Mailbox Databases to Client Access Server Array

Set-MailboxDatabase MDB03 -RpcClientAccessServer “outlook.myexchangeserver.com”

Verifying the Mailbox Database RPC Settings using Get-MailboxDatabase

Now our outlook clients will connect to NLB Cluster name

We can verify the Server connection from Outlook by using Press Ctrl + Right Click Outlook icon in system tray and check the

Connection status.

Configuring Exchange Settings on IPhone

Configuring Your IPhone to us MS Exchange Mailbox

New Concept of using Email from Smart Phones for Business users,

The Apple iPhone offers Exchange ActiveSync functionality were users can Exchange Mailbox account and Sync Emails,Contacts,Calenders .When a user uses the Apple iPhone to synchronize e-mail messages, all e-mail messages in their inbox are synchronized to the iPhone. Users can’t limit the synchronization to only 3 days of e-mail messages as they can with other phones.

Let’s Begin

On the iPhone, go to Settings, then Mail, Contacts, Calendars and create a new Microsoft Exchange account.

    

Add Account

Select Microsoft Exchange

 

Enter Full Email address, Domain Name, User account and password Details,

 

Once clicking Next, You will be asked to enter the server name, So Enter the Server name

And Use SSL One

Now we need to set the Mail , Calender, Contact settings

Here if you can See we can Sync our emails with no limit

Now you can Send and receive Emails from our IPhone Enjoy it…..

Hello Everyone

Here is my First blog about Exchange 2010 Unattended Installation Mode.

Let’s discuss about the deployment Scenario for Exchange 2010 in Unattended Mode,

Types of Setup

We have Following Types of Setup which we can perform for Exchange server

1) Exchange Setup GUI:  We can run the Exchange 2010 Setup wizard GUI Mode

2) Exchange Unattended Setup: Setup.com is an unattended which we need to perform using Command prompt or through a script

Before we start our setup we need to install the prerequisites

Prerequisites

  • We need to make sure that our Forest Functional Level is windows 2003 Active Directory
  • Minimum OS should be Windows Server 2008 with SP2 64bit or Windows Server 2008 R2 must be installed for Exchange 2010 server
  • Configure Raid as per your requirement.
  • Make Sure to  install Windows Updates
  • Permissions for deploying Exchange 2010
    • Schema Admins
    • Domain Admins
    • Enterprise Admins
    • Local administration rights on the server
  • Imp Note: If we you are planning for DAG (Database Availability Group) We Must install Windows Enterprise 2008 Sp2 or R2 because The Standard Edition doesn’t support the features needed for DAG.
  • Make Sure the IP Settings are proper
  • Microsoft Office Filter Packs http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=17062
  • Adding  Import-Module ServerManager from Power Shell
  • Add-WindowsFeature cmdlet to install the component

We are deploying the following roles in Exchange 2010 

Client Access, Hub Transport, and Mailbox server for this we need the following features: 

Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,Web-Asp-Net,Web-Client-Auth,Web-Dir-Browsing,Web-Http-Errors,Web-Http-Logging,Web-Http-Redirect,Web-Http-Tracing,Web-ISAPI-Filter,Web-Request-Monitor,Web-Static-Content,Web-WMI,RPC-Over-HTTP-Proxy –Restart

 

After the restart launch another elevated Windows PowerShell console and run the following command

Set-Service NetTcpPortSharing -StartupType Automatic

 

Just a quick Note:

Before Exchange 2010 SP1 released we need to install this components manually

Now Exchange SP1 has new deployment Functionality were it will install all the components automatically

 

More information

http://technet.microsoft.com/en-us/library/ff818076.aspx

We can now select the /InstallWindowsComponents parameter during an unattended install of Exchange 2010 SP1

Also we need to install some of the Hotfixes if we are deploying

Exchange 2010 SP1 and SP2 Hotfixes for Windows Server 2008 R2

List of Hotfixes

KB979099

KB979744

KB983440

KB977020

For more information you can use this link

http://technet.microsoft.com/en-us/library/bb691354.aspx

Before we install Exchange Server in our Organization we need to prepare schema and AD

Setup.com /Prepareschema or Setup.com /PS

To run this command you should have schema admin rights and Enterprise Admin.

Setup /PrepareAD /OrganizationName:organization name

Once we are done with Prepare schema same as we need to run prepare AD.

Lets begin the Setup

setup.com /mode:install /role:CA,MB,HT,MT /organizationName:MyExchangeserver

This command we need to run to install the following roles Client Access Server,Mailbox & Hub-Transport

Now we need to restart the server

Verifying Our Exchange server setup.

Here is very important thing which we need to check to verify our setup.

Microsoft Recommends to verify the setup by using Get-ExchangeServer Cmdlet or by reviewing the Setup logs file.

We can use this CMD to check Full information about our Exchange Server

Get-ExchangeServer |FL

Or

You can find the setup log at <system drive>\ExchangeSetupLogs\ExchangeSetup.log. The <system drive> variable represents the root directory of the drive where the operating system is installed.
