I never try this utitlity but today I was testing this in a new deployment process and Now I say, it is wonderfull, really we can join member servers and workstations from instalation media with Setup /unattend:AutoAttend.XML and Djoin.exe for example: 1. In a domain controller or member of your domain Windows 7 or WIndows 2008 R2, run in Command Prompt: C:\>Djoin /provision /domain mydomain.loc /machine WorkstationName1 /savefile JoinWorkstationName1.txt Note: You should be administrative rights to join machines in you domain. 2. In the new workstation or member server run in Command Prompt: C:\>Djoin /requestODJ /loadfile JoinWorkstationName1.txt /windowspath %SystemRoot% /localos 3. Restart the new machine or run  shutdown /r /t 00 if you run a Windows Server Core installation. Requirements: Windows 7 or Windows 2008 R2. Administrative rights in domain to join computers and adminstrative rights in the new member machine. See: http://technet.microsoft.com/en-us/

When I was migrating exchange 2000 to exchange 2007, the system prompt this problem: "The Exchange server address list service failed to respond. This could be because of an address list or email address policy configuration error. " "El servicio de lista de direcciones de servidor de Exchange no respondió. Esto puede ser debido a un error en la configuración de la directiva de dirección de correo electrónico o de la lista de direcciones." Cause 1 The CN=Public Folders object is missing under CN=All Address Lists in the Active Directory directory service. Cause 2 The Allow inheritable permissions from the parent to propagate to this object and all child objects check box is not selected on the CN=All Address Lists object and on the CN=Public Folders object. Note This may be the cause in an organization in which you modify permissions to configure separate address lists for different groups. Cause 3 There is a parenthesis or an ampersand in a recipient

[ERROR] Cannot find at least one domain controller running Windows Server 2003 Service Pack 1 or later in domain 'DC=DCName,DC=com,DC=DCName'. This could be the result of moving domain controller objects in Active Directory. Check that at least one domain controller running Windows Server 2003 Service Pack 1 or later is located in the 'Domain Controllers' organizational unit (OU) and rerun setup. It happen when you are installing or upgrading Exchange 2007 in an Active Directory that has only Windows Server 2008 R2 Domain Controllers or yours Windows Server 2003 domain controllers that are not updated to at least Windows Server 2003 SP1.

This security update resolves two privately reported vulnerabilities in Microsoft Windows. The more severe of these vulnerabilities could allow remote code execution if messages received by the Internet Authentication Service server are copied incorrectly into memory when handling PEAP authentication attempts. On Windows Server 2008, the Internet Authentication Service is replaced by Network Policy Server (NPS). An attacker who successfully exploited either of these vulnerabilities could take complete control of an affected system. Servers using Internet Authentication Service or Network Policy Server are only affected when using PEAP with MS-CHAP v2 authentication. This security update is rated Critical for Windows Server 2008 for 32-bit Systems Service Pack 2 and Windows Server 2008 for x64-based Systems Service Pack 2. For all other affected and supported releases of Windows, see the subsection, Affected and Non-Affected Software , in this section. See: http://support

Overview Securing servers, client computers, and mobile devices becomes even more vital as workers and contractors connect from multiple wired and wireless networks that may employ varying levels of security features. Employees can inadvertently put their businesses at risk by connecting to mission-critical systems over mobile networks and applications and unintentionally transmitting viruses or corrupt data. In addition, passing critical corporate data through an outside network operations center may increase the risk of compromise or unavailability. With the right technologies and network architecture in place, however, network administrators can help dramatically improve the security and management of mobile device connections. The key to a successful deployment is carefully planning how to handle permissions and security rights for these mobile workers. Microsoft® products offer a broad set of security-related technologies to help you construct a sound defense against in

Si recibes una linda pantalla rosa cuando estas actualizado tu ESX 4.0 a ESX 4.0 U1 con VMware Update Manager o VMware Host Update Utility, debes reiniciar y detener los HP Insight Manager agents antes de realizar el proceso.

  Hace algunos días, me preguntaban como configurar los DNS primario y secundario de los controladores de dominio, pues bien aquí dejo las opciones que tenemos al realizar esta configuración: Configure the Preferred DNS server in TCP/IP properties on each Domain Controller to use itself as Primary DNS Server. Advantages: Ensures that DNS queries originating from the Domain Controller will be resolved locally if possible. Will minimize impact of Domain Controller’s DNS queries on the network Disadvantages: Dependant on Active Directory replication to ensure that DNS zone is up to date. Lengthy replication failures may result in an incomplete set of entries in the zone. Configure all Domain Controllers to use a centralized DNS server as their Preferred DNS Server. Advantages: Minimizes the reliance on Active Directory replication for DNS zone updates of Domain Controller locator records. This includes faster discovery of new or

Upgrading virtual hardware in ESX 4 may cause Windows 2008 disks to go offline. Upgrading virtual hardware from version 4 to version 7 may cause Windows 2008 disks to go offline. Creating a new virtual machine on hardware version 7 may cause Windows 2008 disks to go offline. Note : The first disk (C: drive) is not affected. Any additional disks may be affected and show marked as Offline within Disk Management. The default SAN Policy on Windows Enterprise is to not automount SAN disks, resulting in the disks being shown as offline. In comparison for Windows Standard Edition, the SAN Policy is online. This can be resolved by changing the SAN Automount Policy on the system. See the Microsoft article http://support.microsoft.com/kb/973834 to change the SAN Policy to online.

The procedure to reset a lost VMware ESX server password is the same in vSphere and ESX4 as it was in VI3 and ESX 3.x. That procedure is: · Go to the console and reboot your ESX host (of course, making sure that all VMs are powered off or migrated off) · When the ESX server reboots, press "A" when you see the ESX GRUB boot loader to modify the kernel arguments. · The default kernel options will appear. Add the word "single" after those options. · ESX will boot into single user mode and you will get a # prompt. · From here, just use the passwd command to change the root user password · Finally, reboot the server

This article guides you through recreating a lost header/descriptor file. You may need to recreate a missing header/descriptor file if: The virtual machine disk is missing when viewing the VM folder from a Datastore browser You can see the –flat.vmdk file does exist when connected to the host via command line The .vmdk descriptor file for the virtual machines disk does not exist or is corrupted When powering on a virtual machine you see a File not found error The disk drives of a virtual machine are represented by a pair of .vmdk files. One is a small text file, containing descriptive data about the virtual hard disk. The second is the actual contents of that disk, and is usually the same size as the drive. For example, a 10GB disk has a 10GB .vmdk file. These content files have -flat appended to the name of the virtual machine, like virtualDisk-flat.vmdk. The descriptive file of this set is virtualDisk.vmdk. See: http://kb.vmware.com/selfservice/mic
