A Windows Based Computer that is connected to your network via an IP Phone (NAP-Enabled) may not connect to the same VLAN after resume from hibernation

This issue applies to Windows XP – SP3, Windows Vista – SP2, Windows Server 2008 – SP2, Windows Server 2008 R2 – SP1 and Windows 7 – SP1.

This issue occurs on networks that use IEEE 802.1X authentication where the client computer or server machine is connected or bridged via a NAP-Enabled device such as an IP or VoIP Phone Handset.

The issue will not be resolved for Windows XP because it is now outside the mainstream support cycle.  Hotfixes for the other operating systems listed above can be obtain via Microsoft KB 976373 http://support.microsoft.com/kb/976373

Windows Vista and Windows 7 – USB Audio Device or USB Headset can cause High CPU Usage and you may notice skipping in the sound playback

If you use a USB Headset, USB Speakers or USB Sound Card under Windows Vista or Windows 7 you may notice that the CPU Usage is very high when you are listening to sound, music or gaming.  You may also notice that the audio lags or skips as a result, this will normally occur every 10-20 seconds and may get worse over an extended period of time.

This is most likely to occur when the device is connected to a USB 2.0 EHCI (Enhanced Host Controller Interface)

The issue is caused by a problem with the usbport.sys driver that is part of Windows

The issue can be addressed in Windows 7 or Windows Server 2008 R2 by upgrading to “Service Pack 1”

The issue can be addressed in Windows Vista – Service Pack 2 or Windows Server 2008 – Service Pack 2 by applying the hotfix from http://support.microsoft.com/kb/981214 which includes an updated version of usbport.sys

Windows 7, Server 2008 R2 and SBS 2011 RTM or SP1 – svchost.exe may hold a lock on a service and cause slow Windows startup

You may find that svchost.exe holds a lock on a service whilst all the service libraries are being loaded.  This in turn then prevents any other services in the same instance of svchost.exe from starting up until the call to the function has been returned.

An updated version of svchost.exe that will address the issue is available here http://support.microsoft.com/kb/2510636

Intel Network Adapter Diagnostics May Wrongly Report that the Network Cable is over 100 Metres Long

When you run a Cable diagnostic using the Intel PROSet Network Adapter Diagnostics you may find that the utility incorrectly reports that your network cable is over 100 Metres and/or that the Cable is faulty/poor.

This issue can occur if you have a network switch that implements “power Saving” or “Green Ethernet” this feature is meant to reduce the power to a network port that is supporting a device with a short network cable run.

This “power saving” or “Green Ethernet” feature can cause the diagnostics to fail and can sometimes contribute to network drops and/or poor network throughput.  If you have a managed/smart switch then you can normally login via a browser and “Disable” this feature to correct the issue.
