Excellent article on this issue in Exchange 2010 and points out why sysprep and unique SID’s are so important

RPC Encryption – Exchange 2010 and Outlook 2003

By default Outlook 2003 does not encrypt traffic between itself and the Exchange server it connects to.

With the introduction of Exchange 2010 RPC traffic between the Exchange server and Outlook must be encrypted by default.

To get around this with Outlook 2003 clients you must either use Group Policy to enable RPC encryption or disable the requirement for encryption on all Exchange 2010 CAS servers. To do this run the following common in the EMS.

Set-RpcClientAccess –Server CAS1 –EncryptionRequired $False

Without making one of these changes Outlook 2003 clients will not be able to connect to the Exchange 2010 CAS.

Update Rollup 2 available for Exchange 2007 SP2

Here is the lists of fixes it covers:

KBA 972076 lists all the fixes included in this rollup. Here are some of the product improvements and critical bug fixes we'd like to call out:

1. KB 972705: This one is for all the IT pros and anyone who has ever had to explain abnormal database size/log file growth in a short period of time. We have added three new registry entries to help speed up troubleshooting the issue:
   • BytesLogWarningThreshold
   • BytesLogErrorThreshold
   • BytesLogCheckPeriodInMinutes
   More information on the values to set in the above registry keys is documented in KB 972705.
2. KB 975404: Accepting meeting requests sent via an application using CDO like Blackberry devices sometimes results in rendering an embedded message attached to the meeting request inaccessible.
3. KB 976137: We have made a change to the behavior of the Unified Messaging Auto attendant when it plays the greeting for callers on a holiday. Currently when callers call on a holiday, they hear the non-business hours greeting followed by the holiday greeting. In this rollup we have made a change so that the callers calling on a holiday will only hear the holiday greeting. If your greetings are configured such that they would make sense to callers calling on a holiday only if they hear both the non-business hours greeting and the holiday greeting, then you need to re-configure them when you install this update rollup.
4. KB 971177: Another change in the UM Auto Attendants configuration in the Exchange Management Console. It is now aware if your time zone follows Daylight Saving Time.
5. KB 975165: In an environment using self-signed certificates and CAS-CAS proxying, Exchange Web Services requests proxied may start failing after the Availability Service has made a proxy request.
6. A bug where the OWA Virtual Directory cannot be accessed via the Exchange Management Console in an environment coexisting with Exchange 2010 if the Exchange 2007 server was upgraded from Exchange 2007 SP1 to SP2.
