You will see an EXE file named "Setup". Double clicking on it will open up a setup and will install a program on your computer named "SDFormatter" Open the above program and select the appropriate windows drive you assigned to your SD card (in my case it was H:\) DO NOT change any option; just click on format. ignore any warning message (s) that shows up. Now, once you finished formatting your SD card go ahead and download this file, This is a Windows Image Burner utility to properly burn BN Factory Image on your SD card: https://launchpad.net/win32-image-wr...ger-binary.zip Step 2: Unzip the "BN_Recovery_1.42" File you just downloaded on your desktop. When you unzip the file, you will see a folder named "bn_142_factory_recovery" on your desktop Under that folder you will see an IMG file names "repart" (Also listed under Step 1) Now, go ahead and unzip the Win32 Disk utility folder you downloaded from here: https://launchpad.net/win32-image-wr...ger-binary.zip After unzipping you will see bunch of files. we are only interested in "Win32diskimager". This is an EXE file so go ahead and double-click on it You will see a blank image path, a folder icon next to it followed by a drive path (defaulted to the drive you assign for your SD card) Click on that blue folder icon and locate the IMG file named "repart" under BN_142_factory recovery folder on your desktop (or wherever you saved it) once you select the image path to correct file, go ahead and select the correct drive for your SD card (in my case it was H:/) once this has been done, click on "Write". You will have a warning message pops up saying this process will completely erase your SD card. JUST go ahead and click "ok" Now, sit back and enjoy. In 1-5 minutes you will see "DONE" dispalyed on lower left hand corner of the program windows "Win32diskimager" Once you see that "DONE" displayed - remove your SD card from your computer Put that SD card in your Nook Tablet Connect your Nook to your PC/Laptop Hold the power button of your Nook until you see "n" logo pops up release the powe button, in 1-2 minutes you will see a messsge "Please DO NOT turn off your device.....installing new software" Now DONT do anythign to your Nook - Just sit back and relax Once Nook finishes installing IMG, a "Green Checkmark" will appear on top right hand corner Remove your SD card from your Nook Tablet You will see Nook will restart itself Then you will be see a message displaying "Clearing Data" Afterwords you will see a message displaying "Installing factory Software...Do not Turn off your device" Once the above process finishes, your Nook will restart itself and then you will be see a "regular Nook setup" screen Now, you have yourself a Complete Factory Version of Nook; Please Note that THIS will WIPE everything. That means you will have a Brand New Nook just like when you first bought it from BN. A clean and EMPTY NOOK! This will erase ROOT, Your Personal Information and Data. Thanks to raywaldo, Meghd00t and todd3835. If i help you out PLEASE dont forget to hit THANKS. Good Luck, Aspi PS: PM me if you are having any issues with my instructions here. Update; If you have followed every steps from above instruction and still getting "please contact nook support" then you have "erased" factory partition table which means that now your device doesn't have any "build history" associated with it, like serial number, build info and so on. That means that factory ROM will not be able to run without getting that information from your device so your best choice is to call BN or go to BN and get a warranty or replacement service.

The image will work fine to restore both 8GB and 16GB units, so you can clarify that in the title. You don't really need to sdformat the sdcard before since the image contains a partition table with 2 partitions already, however you will need that sdformat tool to clear the 2 partitions and reuse the card.

Exchange 2007 SMTP Protocol Logging

source: http://clintboessen.blogspot.com/2009/06/exchange-2007-smtp-protocol-logging.html

To enable protocol logging in exchange 2007 you need to do it on either the Recieve Connector or the Send Connector themselves.

To enable outbound SMTP logging use Set-SendConnector "Connector Name" -ProtocolLoggingLevel verbose. By default it is set to none.

To enable inbound SMTP logging use Set-RecieveConnector "Connector Name" -ProtcolLoggingLevel verbose. By default it is set to none.

By default outbound logs are stored here:
C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpSend

By default inbound logs are stored here:
C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\ProtocolLog\SmtpReceive

Exchange Information Store is stopped, Event ID 4001 in Eventviewer

I have solved the issue but I am going to put the answer to your questions here in case anyone else has similiar symptoms.

I had run all these before and they all passed except when I ran the DCDiag /S:apr-tst-dc1 /TestNS /DNSRecordRegistration.  If I ran that test on the domain controller, it would pass.  If I ran it on the Exchange server, it would fail.  Even after I fixed the 4001 Error, that behaviour still continues.

Anyway the solution was to update the drivers to the most current version and then turn off "Offload Checksum" option on the NIC.  Once I did this, all my AD Replication errors and Exchange Errors went away.

HI,

below article nicely describe about offload Checksumming,I have quote below statements from there.

Quote When data comes in through a network, it's "checksummed," meaning the data is checked against a checksum (or validation code) in the headers in the packets it was delivered in. If the data and checksum don't match, the packet is determined to be bad and has to be retransmitted.

To speed things up, some network cards can "offload" the checksumming, i.e., perform the checksumming on the network card itself, rather than leave the job to the CPU. This frees up the CPU to do that much more work on its own and on a server with extremely high network throughput, that much CPU savings can add up.

To disable checksum offloading:

1.   Open the Registry and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

2.   Add a new DWORD value named DisableTaskOffload and set it to 1.

3.   You may need to restart the system to make these changes take effect. 

Note:-Please take the backup of registry before do changes.

Exchange users cannot access email on smartphone - Security Permissions error

source: http://support.microsoft.com/kb/2579075

To work around this issue, assign the Exchange Servers group the right to change permissions against msExchActiveSyncDevices objects. To do this, follow these steps:

1. Start Active Directory Users and Computers.
2. Click View, and then click to enable Advanced Features.
3. Right-click the object where you want to change the Exchange Server permissions, and then click Properties.
   I did this on the select users that needed access to ActiveSync and it worked. I tried it first on the Domain and it appears to not have worked and inheritance is enabled?!?
   Note You can change permissions against a user, an organizational unit, or a domain.
4. On the Security tab, click Advanced.
5. Click Add, type Exchange Servers, and then click OK.
6. In the Apply to box, click Descendant msExchActiveSyncDevices objects. Don't worry about the 'Descendant' part, just use msExchActiveSyncDevices
7. Under Permissions, click to enable Modify Permissions.
8. Click OK three times.
