Running PEAP with Cisco Aeronet 1231G and Cisco Wireless IP Phone 7925G

To run WiFi with WPA and PEAP using Cisco Aeronet and Windows IAS/NPS, you need the following:

Cisco Aeronet Access Point
Windows Server (2003/2008) running IAS/NPS as the Radius server
Server authentication certificate (commercial or self-signed)

Setting the Access Point

Create a new radius server, point it to the Windows IAS/NPS (installed later). Speficy the shared secret and port for authentication and accounting

Set the default server priorities to or the new Radius server's IP address you just added

Navigate to Security - SSID Manager

Create a new SSID, attach it to the VLAN and tick the Radio checkbox

For Client Authentication Settings, tick Open Authentication with EAP and Network EAP. Change the Server Priorities to Customize or use defaults

For Client Authentication Key Management, select Mandatory for Key Management and tick WPA

SSID Settings. (optional) select Multiple SSID if you are running this SSID as multiple SSID

Navigate to Security - Encryption Manager

Select Encryption Modes to Chipher with AES CCMP + TKIP

Select Encryption Keys to Key 2 and let the value blank

Setting IAS/NPS

Once the NPS installed, run the wizard to setup the Wireless network.
We need to add a radius client which is the IP address of the Cisco Access Point

Navigate to Advancced tab, select the vendor name to Cisco

Navigate to Policies and select Connection Request Policies. Select the Secure Wireless Policy

Most of the following settings are the default value

Navigate to Use Windows authentication for all users. The following settings are having the default value

Navigate to Secure Wireless Connections. The following settings are having the default value

We specify which AD Security Group has access to this policy

Up to this stage, you need to import a server authentication certificate. This can be a commercial certificate or self-signed certificate. If you use self-signed certificate, you need to make sure the clients machine that is going to connect to this WiFi must trust the Root CA who generate this certificate

Select Microsoft Protected EAP (PEAP) and select Edit

If you have the certificate installed correctly, you should see the option which certificate you want to use

On the Settings tab

CCNA Voice

Yesterday, I passed the 642-436 CVOICE 6.0 which makes me officially a CCNA Voice, yahoo!! CCVP here I come...

BES Upgrade 4.1.7 to 5.0.1

Recently we had to upgrade BES 4.1.7 to BES 5.0.1.
We use the following methods and upgrade was a success:

- Prepare the new server (e.g. set local permission for BESadmin, install MAPI Client and CDO, etc)

- Stop and disable all the BES Services on the old BES

- (optional) Take a backup of the BESMgmt database from the old SQL server

- From the new BES Server, run the Tools\BB50preptool.exe, specify the old SQL server and the BESMgmt database. This will prepare the database to be upgradable to ver 5.x

- Take another backup of the BESMgmt database

- Restore the database to the new SQL server

- Edit the database

In SQL Manager expand the BESMgmt database and select Tables. In the centre window right mouse click ServerConfig and select Open Table. Now edit the columns below and update them to display the new server name

-ServiceName
-MachineName
-RPCEndPoint (only edit the name after “\pipe\BESMonitor” )

Still within the ServerConfig table scroll to the MDSAGConfigId column and ensure it is set to NULL. Now close the ServerConfig table and reselect the Tables fold in the left column and locate the MDSAGConfig table in the centre section. Once again right mouse click and select Open Table and ensure you can only see one row containing all NULL values. If a row containing server settings appears select that entire row and delete it.

You can now close the MDSAGConfig table and we can now be assure no old MDS Service settings are migrated and they can be installed fresh on this new server.

Now select the Tables folder in the left column again. In the centre window right mouse click MDSConfig and select Open Table. Now edit the columns below and update them to display the new server name.
-MDSHost
-MachineName
-ServerName (only edit the name before “_MDS-CS_X”)

- From the new BES Server, run the setup.exe. Select use existing database and point it to the new SQL server

After finished installing, reboot the BES Server

You may get the following error in the System Event Log:

Application popup: BBConvert.exe - System Error : The program can't start because WMVCore.DLL is missing from your computer. Try reinstalling the program to fix this problem.

If so, run the following command: (for Windows 2008 R2)

Pkgmgr.exe /ip /m:"%windir%\servicing\Packages\Microsoft-Windows-Media-Format-Package~31bf3856ad364e35~amd64~~6.1.7600.16385.mum"

Exchange 2010 Migration - Part 6

To uninstall the existing Exchange 2007 mailbox role, the public folder database of it has to be removed

Part 6 - Exchange 2007 Public Folder Removal

Environment:
1 x Exchange 2007 SP2 (Mailbox)
1 x Exchange 2010 (CAS, Hub and UM)
1 x Exchange 2010 (Mailbox)

Move all the replica from the 2007 to 2010. From the Mailbox server of 2007, run this command:

[PS] MoveAllReplicas.ps1 -server -NewServer

Then try to remove the Public Folder database from the Exchange 2007. You might get the following error:

Object is read only because it was created by a future version of Exchange ...

If you do, you need to run the following PS from the Exchange 2010:

[PS] C:\>Remove-PublicFolderDatabase -Identity "\Second Storage Group\Public Folder Database"

If the removal is done, you can start deleting the Storage Group and uninstall the Exchange 2007 Mailbox role

Exchange 2010 Migration - Part 5

Exchange 2010 has a built in support for MWI and I am using a Cisco Phone which has MWI feature

Part 5 - Exchange 2010 MWI (Message Waiting Indicator)

Existing Environment:
1 x Exchange 2007 SP2 (Mailbox)
1 x Exchange 2010 (CAS, Hub and UM)
1 x Exchange 2010 (Mailbox)

If you do not enable the MWI of your SIP trunk between your Exchange UM and CUCM, you will get this event log warning:

The Unified Messaging server failed to deliver the MWI notification '1/7 (unread/read)' for the UM-enabled mailbox '(3037b9d1-3554-45af-8a68-077e54104120)' associated with UM extension 'xxxxx'. Additional information: Microsoft.Exchange.UM.UMCommon.MwiNoTargetsAvailableException: There are no more targets available to send an MWI message for user .

To get it working, you need to do the following:

Login to CUCM, go to System - Security Profile - SIP Trunk Security Profile
Find the SIP Trunk Security Profile that is being used by the SIP trunk between Exchange UM and CUCM
Edit it and make sure the option Accept Unsolicited Notification is enable and reset the trunk

Exchange 2010 Migration - Part 4

Since my mailbox been migrated to the Exchange 2010 mailbox, I wasn't been able to receive my voicemail through my Outlook

Existing Environment:
1 x Exchange 2007 SP2 (Mailbox)
1 x Exchange 2010 (CAS, Hub and UM)
1 x Exchange 2010 (Mailbox)

Part 4 - UM and Hub Transport Issue

The following error occurred on my UM/Hub Transport server:

The Unified Messaging server failed to submit a message to Hub Transport server 'Hub01' due to the following error: Unexpected SMTP server response. Expected: 220, actual: 500, whole response: 500 5.3.3 Unrecognized command

According to some forums, this occurs because the communication between the UM and Hub Transport server is using TLS and I don't have a valid SSL certificate.

To fix this, either buy a valid certificate and assign it to the UM and SMTP service or do the following:

Find the Receive Connector (within Server Configuration - Hub Transport) that most likely to be used by the UM to communicate with the Hub Transport. Usually it will use the more specific network addresses from the network tab of its properties
On the Authentication tab, untick all TLS related options. Make sure Exchange Server authentication is selected
On the Permission Groups tab, make sure Exchange servers is selected
Restart Transport and UM Exchange services

Exchange 2010 Migration - Part 3

Since my user account has been migrated to Exchange 2010, my iPhone ActiveSync is broken.

Existing Environment:
1 x Exchange 2007 SP2 (Mailbox)
1 x Exchange 2010 (CAS, Hub and UM)
1 x Exchange 2010 (Mailbox)

Part 3 - ActiveSync Issue

The following event log will be seen on the CAS server:

Exchange ActiveSync doesn't have sufficient permissions to create the "CN=User,OU=Users,DC=domain,DC=local" container under Active Directory user "Active Directory operation failed on dc.domain.local. This error is not retriable. Additional information: Access is denied.Active directory response: 00000005: SecErr: DSID-03151E04, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0".Make sure the user has inherited permission granted to domain\Exchange Servers to allow List, Create child, Delete child of object type "msExchangeActiveSyncDevices" and doesn't have any deny permissions that block such operations.

It turns out that the AD user account is a member of the protective group (e.g. Domain Admins).
To fix this, remove the user from the protective group, go to the user's properties - security - Advanced and tick "Include inheritable permissions from this object's parent"

I had to remove my exchange account from my iPhone and re-add it back to make it work.

Exchange 2010 Migration - Part 2

Existing Environment:
1 x Exchange 2007 SP2 (CAS,Hub and UM)
1 x Exchange 2007 SP2 (Mailbox)
1 x Exchange 2010 (CAS, Hub and UM)
1 x Exchange 2010 (Mailbox)

Part 2 - Migrate Users

From Exchange Management Console - Add a local move request to move user mailbox

I have CUCM that was setup with SIP trunk to the 2007 UM, so I need to re-point it to the 2010 UM - Change CUCM SIP Trunk to 2010 UM's IP Address

Generate SSL Cert for 2010 CAS - Go to IIS 7 of the CAS and generate CSR. Replace the self-signed SSL cert with the new one

I am using ISA 2006 to publish Outlook Web App and ActiveSync - Change owa and ecp authentication to Basic. Do this from EMC - Server Configuration - Client Access

Change ISA OWA publishing rule to point to the new 2010 CAS
Change ISA OWA publishing rule to add /ecp/* to the paths of the publishing rule

Exporting Active Directory Group Membership

Save this code as a .vbs file:

Dim objGroup, objUser, objFSO, objFile, strDomain, strGroup, Domain, Group

'user Input box
strDomain = Inputbox ("Enter the FQDN Domain name, e.g. domain.com", "Domain Name", "Domain Name")
strGroup = InputBox ("Enter the NetBIOS Group name, e.g. mygroup", "Group Name", "Group Name")

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.CreateTextFile("C:\temp\" & strGroup & ".txt")
Set objGroup = GetObject("WinNT://" & strDomain & "/" & strGroup & ",group")

For Each objUser In objGroup.Members
objFile.WriteLine objUser.Fullname & " (" & objUser.Name & ")"
Next

objFile.Close
Set objFile = Nothing
Set objFSO = Nothing
Set objUser = Nothing
Set objGroup = Nothing

Wscript.Echo "Group Membership Exported to the file: " & "C:\temp\" & strGroup & ".txt"

Simple Trick - CAG SSL Certificate Installation

It is a very painfull process to install an SSL certificate to the Citrix Access Gateway appliance.

The easiest way is to generate the CSR from any IIS server, generate/purchase the SSL certificate using that CSR and install the signed certificate/public key to the IIS where the CSR was generated from.

Next is to export that certificate (including the private key) from IIS as PFX format

Next is to convert this PFX format certificate to PEM format using the tool (Google this: pfx2pem)

Install this PEM format certificate to CAG
