How to provision shares remotely in a Windows Server 2008 failover cluster

an error occurs if you try to provision a share remotely and if the highly available service or the application group is not local to the cluster node. You may receive the following error message:

<Client_Access_Point_Name>: Virtual Disk Service initialization failed. It is possible that the connection is blocked by Windows firewall. A VDS (Virtual Disk Service) error occurred while performing the requested operation.

To enable the provision shares functionality remotely, modify Windows Firewall on all nodes in the cluster. To do this, follow these steps:

1. Click Start, click Control Panel, and then double-click Windows Firewall.
2. Click Change settings.
3. Click the Exception tab, click to select the Remote Volume Management check box.
4. Click OK.

Windows Control Services

 Si alguna vez se te colgo un servicio o quedo en estado  START_PENDING y no sabias como matarlo.... Aca te paso la solucion

  1. Go to the command-prompt and query the service (e.g. the SMTP service) by using sc:

    sc queryex SMTPSvc
  2. This will give you the following information:

    SERVICE_NAME: SMTPSvc
            TYPE               : 20  WIN32_SHARE_PROCESS
            STATE              : 4  RUNNING
                                    (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN)
            WIN32_EXIT_CODE    : 0  (0x0)
            SERVICE_EXIT_CODE  : 0  (0x0)
            CHECKPOINT         : 0x0
            WAIT_HINT          : 0x0
            PID                : 388
            FLAGS              :


    or something like this (the "state" will mention stopping).
  3. Over here you can find the process identifier (PID), so it's pretty easy to kill the associated process either by using the task manager or by using taskkill:

    taskkill /PID 388 /F

    where the /F flag is needed to force the process kill (first try without the flag).
Problemas con UPDATE de seguridad de Microsoft MS08-037

Despues de instalar el ULTIMO update relacionado con DNS, las personas que tienen zone alarm instalado, esperimentan problemas de navegacion.

Tanto Microsoft como Zonealarm están trabajando de manera activa para resolver este problema. En una entrevista reciente a un representante de Zonealarm, se informó que estarán liberando un parche para solucionar este problema. Zonealarm puede ser contactado en   http://www.zonealarm.com/

 

 

NO recomendamos desintalar la actualización de seguridad, pues dejaría a la máquina vulnerable.

IIS Applications Stop Responding

Queria compartir con ustedes un problema que se me presento en un FARM de IIS 6.0. El mismo consta de 3 IIS 6.0 como FrontEnd y un cluster windows 2003R2 para alojar los contenidos, que son accedidos via UNC.

Uno de los sistemas de FrontEnd cada tanto dejaba de atender los request de HTTP. Y no se presentaban sintomas de carga tanto de CPU como RED...   Luego de investigar un tiempo encotre que existen ciertos valores de registry que deben ser modificados cuando se configura IIS con los contenidos via UNC.

Esta nota se encontro a raiz de un evento en particular que se encotro en el IIS, el cual paso a detallar.

Event ID 101 on IIS server:
Event Type:Warning
Event Source:W3SVC
Event Category:None
Event ID:101
Date:9/5/2002
Time:8:07:28 AM
User:N/A
Computer:<server name>
Description:
The server was unable to add the virtual root '/<virtual dir name>' for the directory '\\<servername>\<share>\' due to the following error: The network BIOS command limit has been reached. The data is the error code. For additional information specific to this message please visit the Microsoft Online Support site located at: http://search.support.microsoft.com/search/?adv=1.

La solucion a este problema se encuentra detallada en el KB 221790  http://support.microsoft.com/kb/221790/

 

Espero a alguien le sirva.
