NEWS!! 'Flamer' virus could be most sophisticated malware, warns Kaspersky
Be aware!!
28/05/2012
A new virus referred to as 'Flamer' could be one of the most sophisticated pieces of malware yet, Kaspersky has warned.
According to the internet security giant, the Win32.Flamer "attack toolkit" that is currently targeting Iran and other countries in the Middle East offers much more of at threat than most malware attacks.
This is partially due to the complexity of the program, meaning that it is capable of undertaking a wide number of potentially damaging actions.

Como renombrar una cuenta con powershell
Buenas tardes amig@s,
después de hacer un script para crear cuentas de usuarios, casilla y usuario de lync, me dí cuenta que el nombre de la cuenta estaba mal, debería tener el display name en lugar del samAccountname
Acá el script
$user=import-csv .\saMacc.csv
ForEach ($u in $user)
{
$prop=get-aduser -Identity $u.user -property *|select-object distinguishedName,displayname
foreach ($p in $prop) {
Rename-ADObject -identity $p.distinguishedName -NewName $p.displayname
if($error.count -gt 0){
$error[0].ToString()
Write-host "Rename failed :" $u.user
$error.clear()
}
else
{
Write-host "Rename success :" $u.user
}
}
}
Saludos

Error al cerrar la consola gráfica Exchange 2010 "You must close all dialog boxes before you can close Exchange management Console"
Y claro que tenemos todas las consolas cerradas, ¿Por qué pasa?
La consola de Exchange chequea por algun porceso de ventana visible antes de cerrarla, debido a que una ventana oculta de Internet Explorer 9 es considerada como ventana visible, este problema ocurre
¿Cómo se soluciona?
Con un hotfix, lo he probado en el lab y luegoen producción y funciona perfecto, ojo que pide reinicio de server.
Bajalo de acá ....shhhhhhhhhhhhhhhhh

The Exchange Team is pleased to announce that in the second half of calendar year 2011 we will be releasing Exchange Server 2010 Service Pack 2 (SP2) to our customers. With SP2, the following new features and capabilities will be included:
- Outlook Web App (OWA) Mini A browse-only version of OWA designed for low bandwidth and resolution devices. Based on the existing Exchange 2010 SP1 OWA infrastructure, this feature provides a simple text based interface to navigate the user’s mailbox and access to the global address list from a plurality of mobile devices.
- Cross-Site Silent Redirection for Outlook Web App With Service Pack 2, you will have the ability to enable silent redirection when CAS must redirect an OWA request to CAS infrastructure located in another Active Directory site. Silent redirection can also provide a single sign-on experience when Forms-Based Authentication is used.
- Hybrid Configuration Wizard Organizations can choose to deploy a hybrid scenario where some mailboxes are on-premises and some are in Exchange Online with Microsoft Office 365. Hybrid deployments may be needed for migrations taking place over weeks, months or indefinite timeframes. This wizard helps simplify the configuration of Exchange sharing features, like: calendar and free/busy sharing, secure mailflow, mailbox moves, as well as online archive.
- Address Book Policies Allows organizations to segment their address books into smaller scoped subsets of users providing a more refined user experience than the previous manual configuration approach. We also blogged about this new feature recently in GAL Segmentation, Exchange Server 2010 and Address Book Policies.
- Customer Requested Fixes All fixes contained within update rollups released prior to Service Pack 2 will also be contained within SP2. Details of our regular Exchange 2010 release rhythm can be found in Exchange 2010 Servicing.
We hope these announcements come as welcome news to you. It is our custom to provide ongoing improvements to features, functionality and security of Exchange Server, based largely on customer feedback, and to provide continual innovation on an already great messaging product. We look forward to receiving your comments and announcing more detailed information as we continue to develop the features that will be included in SP2.
