If you try to access the OWA, the IIS Application Pool MSExchangeServicesAppPool crash and stop working.

To solve this issue, open the web.config from the virtual directory and change the following value:

<identity impersonate=”True” /> back to: <identity impersonate=”true” />

to

<identity impersonate=”True” /> back to: <identity impersonate=”false” />

Restart the Application Pool and OWA will work fine.

We migrated a Citrix Presentation Server 4.0 environment to XenApp 5.0 with Windows Server 2008. Everything worked fine, but one user could launch every app, but instead of the app, a Desktop was startet!

After some research, i found the solution. Run the following VB-Script on your Domain Controller and then reenter your Roaming Profile settings.

Const ADS_PROPERTY_CLEAR = 1

Set objUser = GetObject _
(“LDAP://cn=user,ou=sales,ou=district,ou=company,dc=holding,dc=local”)

objUser.PutEx ADS_PROPERTY_CLEAR, “userParameters”, 0
objUser.SetInfo

Publishing Exchange 2010 Services using ISA 2006 works fine. Just select Exchange 2007 as Exchange Version and publish OWA, PushMail and Outlook Anywhere.

The only problem is the new ECP. You have to add a directory manually in the ISA Publishing Rule:

I have a fresh installed Windows Small Business Server 2008 Premium Edition on a VMWare ESX 4i Host. I installed VMWare Tools and disabled IPV6 in the Network Settings. After that, i restarted the machine, bad idea!

The Systems hangs over 30 Minutes on “Applying Computer Settings…”. Several resets didn’t help. After i started the machine in “recovery mode” and disabled IPV6 trough a registry key, the machine is booting as it should.

here is the required registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\

Add a new DWord (32bit):

DisabledComponents with the value “ffffffff” (eight f )

Restart the Server and everything will be fine…

You have to replace a Citrix Server, that hosts your Datastore Access Database? If you have a SQL-Server, i recommend to migrate to SQL, otherwise do the following steps to move the database:

• Copy the file MF20.mdb, usually found in c:\program files\citrix\independent management architecture\ to the new server (same path)
• Stop the IMA Service on the old server. Warning: All Citrix users will be disconnected!
• Open cmd on the new server and execute the dsmaint command.
  exp. dsmaint config /user:username /password:password /dsn: “C:\program files\citrix\independent management architecture\mf20.mdb”
• Restart the IMA Service on the new server
• On the old server, enter the following command in cmd
  dsmaint failover <new server name>
• Restart the IMA Service on the old server.

Your Access Database has now been migrated to the new server. Do not forget to update your backup software

Vom Exchange Server 2007 Nachfolger “Exchange Server 2010″ ist die erste Public Beta erschienen. Folgende Neuerungen bietet Exchange Server 2010:

New Rights-Protected E-Mail Functionality with Active Directory RMS

The following is a list of new rights-protected e-mail functionality with Active Directory Rights Management Services (AD RMS) that has been included in Exchange 2010:

• Transport rules to apply AD RMS protection to messages based on conditions.
• Persistent protection of attachments in rights-protected messages.
• Support for AD RMS templates.
• An Internet confidential AD RMS template for protection over the Internet.
• AD RMS protection for Unified Messaging voice mail messages.

New Transport and Routing Functionality

The following is a list of new transport and routing functionality that has been included in Exchange 2010:

• Cross-premises mail routing An organization can choose to outsource some of their mailboxes to a hosted solution while maintaining their on-premises deployment. For example, a university can choose to host the mailboxes for all faculty and staff in their on-premises deployment and use a hosted solution for student mailboxes. Exchange 2010 allows routing of messages between the on-premises and hosted mailboxes.
• Enhanced disclaimers Exchange 2010 lets you add disclaimers that can include hyperlinks, images, and HTML-formatted text. You can also insert Active Directory attributes that are substituted for the sender’s attributes when a disclaimer rule is triggered.
• Transport rules integration with AD RMS Exchange 2010 gives you the ability to create rules that require AD RMS protection based on keywords or patterns.
• Moderated Transport Exchange 2010 provides an approval workflow for sending messages to recipients. When you configure a recipient for moderation, all messages sent to that recipient must go through an approval process.
• Shadow redundancy Messages that are submitted to an Exchange 2010 Hub Transport server are stored in the transport database until the next hop reports successful delivery of the message. If the next hop doesn’t report successful delivery and it fails, the message is resubmitted for delivery.
• Transport dumpster truncation based on log copy status When messages that are in the dumpster are replicated to all mailbox databases, they’re removed from the dumpster.
• Latency SLA management Exchange 2010 Transport lets you measure service levels delivered relative to your service level agreement (SLA) goals. Exchange 2010 gives you the ability to measure latencies for each hop, as well as end-to-end latency.
• Transport database improvements Performance improvements in the Transport database result in reduced database I/O per second (IOPS) per message, which increases message throughput.

New Permissions Functionality

In Exchange 2010, Role Based Access Control (RBAC) has replaced the permissions model that was used in Exchange 2007. RBAC lets you define extremely broad or extremely precise roles and assignments based on the roles of your administrators and users, and the tasks they perform. Access to the cmdlets and parameters required to perform a task is granted by assigning the related RBAC management role to a user or universal security group. If you want to grant an administrator or user the ability to perform tasks in Exchange 2010, you must either add the administrator or user to a universal security group that already has been assigned a specific RBAC role, or you must assign the role directly to the administrator or user.

New High Availability Functionality

Exchange 2010 integrates high availability into the core architecture of Microsoft Exchange to enable customers of all sizes and in all segments to economically deploy a messaging continuity service in their organization.

Exchange 2010 combines the key availability and resilience features of cluster continuous replication (CCR) and standby continuous replication (SCR) into a single high availability solution that handles both on-site data replication and off-site data replication. Mailbox servers can be defined as part of a Database Availability Group to provide automatic recovery at the individual mailbox database level instead of at the server level. Each mailbox database can have up to 16 copies.

The following features in Exchange 2007 and Exchange 2007 Service Pack 1 (SP1) no longer exist in Exchange 2010:

• Local continuous replication (LCR)
• Single copy clusters (SCC)

New Messaging Policy and Compliance Features

Exchange 2010 compliance features make retention independent of users’ mailbox management and filing habits, and these features ensure retention policies are applied continuously. The following is a list of new messaging and compliance features that have been included in Exchange 2010:

• New interface for applying retention policies
• Auto tagging for retention policies
• Mailbox search features for cross-mailbox search with Advanced Query Syntax (AQS) support
• New transport rules predicates and actions

New Outlook Web Access Features

The following is a list of new features in Outlook Web Access in Exchange 2010:

• Favorites in the Navigation Pane
• Search folders
• Message filtering
• The ability to set categories in the message list
• Options in the Web management interface for Outlook Web Access
• A side-by-side view for calendars
• Multi-client language support
• The ability to attach messages to messages
• Expanded right-click capabilities
• Integration with Office Communicator, including presence, chat, and a contact list
• Conversation view
• The ability to send and receive text (SMS) messages from Outlook Web Access
• Outlook Web Access mailbox policies

New Unified Messaging Features

The following is a list of new Unified Messaging features that have been included in Exchange 2010:

• Personal auto attendants (call answering rules)
• Additional language support including in Outlook Voice Access and Voice Mail Preview
• Enhancements to name lookup from caller ID
• Voice Mail Preview
• Messaging Waiting Indicator
• Missed call and voice mail notifications using text messaging (SMS)

• Text messaging (SMS) integration
• Voice messaging integration
• Mailbox Search
• Distribution list creation and management
• Moderation and approval for distribution list submission

New Exchange Core Store Functionality

• Storage groups are deprecated.
• Mailbox databases are no longer connected to the server object.
• Extensible Storage Engine (ESE) has many improvements for high availability, performance, and database mobility.
• The Store schema has been flattened.

New Administration Functionality in the Exchange Management Console

The core EMC refers to new functionality that affects how you use the Exchange Management Console, not how you use specific features. The following is a list of the new core Exchange Management Console (EMC) features that have been included in Exchange 2010:

• Customer Experience Improvement Program (CEIP)
• Organizational Health
• Community and Resources
• Command logging
• Property dialog command exposure

New Administration Functionality in the Exchange Management Shell

The following is a list of features available in the new Exchange Management Shell:

• Remote administration With the new Shell, you can connect to remote Exchange 2010 servers across the network with only Windows PowerShell V2 CTP3 and Windows Remote Management 2.0 CTP installed.
• Administrator audit logging Actions that result in the modification of Exchange organization configuration and other object properties in the Exchange Management Console, the Web management interface, and the Shell can now be logged for later review. For more information, see Overview of Administrator Audit Logging.

Die BEServer.exe unter BackupExec 11D verursacht einen hohen CPU Load, 20-35% der CPU werden meistens belegt. Anbei zwei Lösungsansätze.

Lösungsansatz 1:

To resolve the problem on servers running 32bit Windows Operating System:

1. Check for a folder named “Temporary ASP.NET Files” in %windir%\Microsoft.NET\Framework\v2.0.50727 directory.

2. If the folder is not present then create a new folder under %windir%\Microsoft.NET\Framework\v2.0.50727 and name it “Temporary ASP.NET Files”.

3. If the folder already exists then delete the folder and re-create it.

4. Restart Backup Exec server service.

To resolve the problem on servers running 64bit Windows Operating System:

1. Check for a folder named “Temporary ASP.NET Files” in %windir%\Microsoft.NET\Framework\v2.0.50727 folder.

2. If the folder is not present then create a folder under %windir%\Microsoft.NET\Framework\v2.0.50727 and name it “Temporary ASP.NET Files”.

3. If the folder already exists then check for the same folder under %windir%\Microsoft.NET\Framework64\v2.0.50727 directory. If the folder is not present then copy the “Temporary ASP.NET Files” folder from %windir%\Microsoft.NET\Framework\v2.0.50727 directory and paste it into %windir%\Microsoft.NET\Framework64\v2.0.50727 directory.

4. Restart Backup Exec server service.

Lösungsansatz 2:

This problem could be cause if the Microsoft report Viewer is not installed property or it got corrupted.  I will suggest you to try first to repair the install of the MS Report Viewer.  If this does not work, the uninstall and reinstall the MS Report Viewer.

To repair or reinstall the MS Report Viewer from the Backup Exec install CD or download, go to the folder “\winnt\install\reportviewer\” and launch the executable reportviewer.exe.  If is installed, this should give you the options to repair or uninstall.
