HTTP and HTTPS requests or traffic to a Windows Vista, Windows 7, Windows Server 2008, SBS 2008, Windows Server 2008 R2 or SBS 2011 machine may exhibit increased latency if the connection is through a network load balancer

If you utilise Microsoft Internet Information Services IIS or an application that uses the System.Net.HttpListener class is installed or running on one the operating systems below, and you have a Network Load Balancer then you may find that Increased latency occurs on HTTP and HTTPS requests and traffic.

This issue occurs because the HTTP and HTTPS requests from clients can include zero length data in the SSL records, certain server-side variables do not update correctly in this instance and Http.sys leaves the connection in the CLOSE_WAIT state.  This intern exhausts the open connection limit can introduce latency, timeouts and connection problems.

Affected Operating Systems:

Microsoft Windows Vista

Microsoft Windows 7

Microsoft Windows Server 2008

Microsoft Small Business Server 2008 – SBS 2008

Microsoft Windows Server 2008 R2

Microsoft Small Business Server 2011 – SBS 2011

The Microsoft Knowledge Base Article KB 2634328 includes further information on this issue and provides an updated version of Http.sys that corrects the issue http://support.microsoft.com/kb/2634328

[RESOLVED] Windows Fax and Scan – Invalid procedure call or argument URL: res://ieframe.dll/preview.js

When you try to use Windows Fax and Scan to send a fax message with content in the body section of the fax you may get an error similar to the following example:

Script Error

Line: 2107

Char: 1

Error: Invalid procedure call or argument

Code: 0

URL: res://ieframe.dll/preview.js

This seems to start occurring after Internet Explorer 9 is installed and currently it seems that the only workaround is to uninstall Internet Explorer 9 or not enter text into the body section of the fax.

Following on from our Microsoft PSS case we have been given two different solutions to this issue, the first is to apply the latest Cumulative Security Update for Internet Explorer.  This can be obtained via Microsoft Update or Windows Update and may have already been installed automatically.  You can find further information here MS11-099: Cumulative Security Update for Internet Explorer: December 13, 2011 http://support.microsoft.com/kb/2618444

Another possible fix for this issue is to apply the hotfix mentioned in Microsoft KB 2647169 http://support.microsoft.com/kb/2647169 this applies to Windows 7, Windows Server 2008 R2 and Microsoft Windows Small Business Server 2011 (SBS 2011).

A case is open with Microsoft PSS regarding this issue and once I have more permanent fix I will post it here.

Here is the official stance from Microsoft on this issue http://support.microsoft.com/kb/2629557

[RESOLVED] You must close all dialog boxes before you can close Exchange Management Console

After installing Internet Explorer 9 on your Microsoft Exchange 2007 or Exchange 2010 mail servers you may have been noticing that the Exchange Management Console will refuse to close and simply state “You must close all dialog boxes before you can close Exchange Management Console”.

This has been a long running issue but has finally been resolved by the Microsoft Internet Explorer Developer Team.

Please note that this issue is now resolved by installing the latest cumulative security update for Internet Explorer, The fix was first included in security update 2618444 http://support.microsoft.com/kb/2618444

Information on the scope of this issue can still be found here KB 2624899 http://support.microsoft.com/kb/2624899

You can request the hotfix by visiting Microsofts website and searching for the following Knowledge Base article KB 2624899

Note: The hotfix is actually for Internet Explorer 9 rather than Microsoft Exchange but does actually resolve the issues with the Exchange Management Console not closing correctly.
