By accident I found a bug in Exchange 2010. The issue only occurs in Exchange 2010 and if you have multiple CAS servers which are located in different sites and can’t communicate to eachother. Till now I only saw the issue with Exchange 2010 where an extra CAS server was added to the mainoffice. In this case this is the 3rd CAS server in the Exchange 2010 environment

Normally you will get a nice overview of all CAS servers when running the get-owavirtualdirectory command. But when no RPC traffic is allowed between the sites you will get the following result:

As you can see the command will display the first CAS server but it goes wrong when it wants to connect to the 2nd CAS server. This is normal because it can’t connect to it via RPC. Normally you would expect that the query will continue to run and will display the other servers, NOT. After contacting Microsoft they confirmed that this is a bug which will be fixed in a future update.

Workaround: open RPC

I know it may sound strange, Chinese signs in non-delivery reports. After some investigation I discovered something which made the problem stranger then I first thought. When the message was printed the text was displayed in Dutch.

When the same mail was sent from an Outlook 2003/2007 client the problem was not there. So I decided to start searching on the internet and after a while I found something on the Technet forum which looked pretty much on the problem I had.

The problem is caused by a bug in Outlook XP which will not be fixed anymore. To make the problem clear I summarized some details below:

• mail-client is Outlook XP
• happens only when a NDR is delivered in HTML format
• when the mail is printed everything look OK

To fix this issue you will need to tell your Hub server that every NDR needs to be sent as a plain-text NDR, this can be done by executing the following Powershell command:

Get-TransportServer | Set-TransportServer –InternalDsnSendHtml $False

Another solution is upgrading your Outlook client to 2003 or higher.

During playing around with Dreamweaver I discovered a nice problem this weekend. Files who were created with Dreamweaver couldn’t be opened anu more. When you did this Dreamweaver crashed. I had some extensions installed so first I deleted those, but that was not the solution . I decided to search on the internet and saw that a lot of people had this issue. The problem was caused by the winter-time that was adjust also in the USA. A bug that was not found during the beta test of the product. The solution is really simple. Delete the file WinFileCache*.dat from the application data\Adobe\Dreamweaver 9\Configuration directory and your problem is solved. If you use Vista then you can find the file in the following directory AppData\Roaming\Adobe\Dreamweaver 9\Configuration
