Test drive the Beta 2 of Exchange 2007 SP1 without impacting your production environment. Check out Standby Cluster Replication (in theory), and some of the Powershell additions since RTM. It is going to be a good service pack!

You could almost consider it a functional product demo for Silverlight, but it does give Windows Live Search a pretty and interactive frontend. Try it out here.

5 issues relating to wireless authentication are fixed with this hotfix.

1. IEEE 802.1X authentication that is based on Virtual Local Area Network (VLAN) switching may fail.

2. In a wireless profile, the information about the Extensible Authentication Protocol (EAP) method that is selected in a user interface may be incorrect.

3. A wireless profile that an independent hardware vendor (IHV) provides may be corrupted after you use the wireless profile user interface to edit the profile. When this problem occurs, you may receive an error message that Windows Explorer has crashed.

4. Every time that you roam to a different wireless access point, you are prompted to provide a user credential. This problem occurs even if you have saved the user credential.

5. You registered a Protected Extensible Authentication Protocol (PEAP) method that the IHV provided. When you try to authenticate against an Internet Authentication Service (IAS) server, the server may reject the authentication, and the IAS server may send an error message that the authentication has failed. The Onex.dll file crashes when this problem occurs.

This finally explains the reason why one of my desktop Vista machines at home could never properly find device drivers, even though the device drivers were included with the installation CD of Vista! I always had to manually point it to certain directories so that it could do the right thing.

I am sure I am not the only one that has encountered this problem!

Excerpts from the KB article:

SYMPTOMS
When you try to install a new hardware device on a Windows Vista-based computer, Windows Vista cannot install the driver for the hardware device successfully. Additionally, you may sometimes receive the following error message:

CAUSE
If the Infcache.1 file is deleted or corrupted, Windows Vista does not recreate the Infcache.1 file.

RESOLUTION
To resolve this problem, install this hotfix. Then, try to install the hardware device again.

This can be handy during a migration from Notes to Exchange 2003 and/or better interop between Lotus Notes URL links and Outlook Web Access. You can now unblock "notes://" URL links with this hotfix.
