Hi All, I'm attempting to clone an ET box. When trying to validate the CloneConfigData on the new ET I get: "Key Length needs to be 16, 24 or 32 bytes long" (????) Anyone seen this before? Thx in advance for any pointers or info. Rgds, Marcus.

Dear customer: In order to better troubleshoot the issue, please help collect the following information. 1. Which command have you run when you encounter the error such as Key Length needs to be 16, 24 or 32 bytes long" (????), post the complete command into the forum. 2. Did you run the ExportEdgeConfig.ps1 script to export the source server's configuration information to an intermediate XML file? 3. Send answer file to v-rocwan@microsoft.com for analyze. Cloned configuration is the practice of deploying new Edge Transport servers based on the configuration information from a previously configured source server. The configuration information from the previously configured source server is copied and exported to an XML file, which is then imported to the target server. You may deploy more than one Edge Transport server in the perimeter network and load-balance network traffic among all Edge Transport servers by defining more than one mail exchange (MX) resource record with the same priority in the Domain Name System (DNS) database for your mail domain. Edge Transport server configuration information is stored in Active Directory Application Mode (ADAM) and is not replicated among multiple Edge Transport servers. By using cloned configuration, you can make sure that every Edge Transport server that is deployed in the perimeter network is operating by using the same configuration. For more information about How to Configure the Edge Transport Server Role by Using Cloned Configuration Tasks, please refer to the following artile: How to Configure the Edge Transport Server Role by Using Cloned Configuration Tasks http://technet.microsoft.com/en-us/library/aa996008(EXCHG.80).aspx Note: when send e-mail to me please attach the subject of the post. Thanks for your time and cooperation. If anything is unclear, please feel free to let me know. Rock Wang - MSFT

Hi Rock, thx for your reply. I had responded to your post yesterday, but for some reason it didn't get posted(??) Anyway: -> 1. the import command as described in the link you also mentioned ./importedgeconfig -CloneConfigData:"c:\CloneConfigData.xml" -IsImport $false -CloneConfigAnswer:"c:\cloneconfiganswer.xml" -> 2. Yes. -> 3. No answer file is created. The command immediately errors out with the above mentioned error. Thx in advance, Marcus.

Dear customer: Thanks for your reply. CloneConfigData.xml file contain all send connector-related information. If any Send connectors are configured to use credentials, the password is written to the intermediate XML file as an encrypted string. You can use the -key parameter with the ImportEdgeConfig.ps1 and ExportEdgeConfig.ps1 scripts to specify the 32-byte string to use for password encryption and decryption. If you do not use the -key parameter, a default encryption key is used. In order to better troubleshoot the issue, please help collect the following information: 1. Did you configure send connector to use credential on source Edge transport server? 2. Which command have you perform when running ExportEdgeConfig.ps1 command, post the complete command into the forum for analyze, does it prompt the command has been successfully? 3. Did the source and new Edge transport server have the same Exchange version? Such as install Exchange server 2007 SP1 or not? 4. Send the export file CloneConfigData.xml to v-rocwan@microsoft.com. 5. Run Exbpa tool on both Edge transport servers, and send the separate .xml file to v-rocwan@microsoft.com, you can perform the following steps: 1) Open EMC, navigate to Toolbox, open Best Practices Analyzer, 2) Click select options for a new scan. 3) Click "Start Scanning" 4) When the scan finishes, Click "View a report" in the left pane and click the report in the right pane 5) Click "Export report", select the type as XML (will save entire data file). 6) Compress the XML and send it to v-rocwan@microsoft.com.
