Multiple desktop sessions for the same user is disabled by default on Windows Server 2008R2. To enable multiple sessions for the same user:

  1. Go to Administrative Tools->Remote Desktop Services->Remote Desktop Session Host Configuration
  2. Select properties on the ‘Restrict each user to a single session’ general setting.
  3. Un-check the ‘Restrict each user to a single session’ checkbox.


After saving all further new remote desktop sessions will be new unless ‘console mode’ RDP is used.

Sometimes when I log in to a remote desktop session it appears as thought the Windows key is stuck on, so pressing keys like ‘L’ always locks the screen.

The workaround I found is this:

In the Local Resources options for the remote desktop session you should set the Apply Windows key combinations to be On the remote computer


Next log in to the remote desktop session.
Press Ctrl-Alt-End to lock the session.
Log in again and the Windows key will become unstuck.

A great little shell extension that opens a command prompt via the context menu in explorer. Has support for UNC paths too :-)

IIS on Windows XP has a default concurrent connection limit of 10 for the root website. Any connections made after 10 connections are being used up are greeted with a HTTP 403.9 Access Forbidden: Too many users are connected error message.
The default connection limit can be changed to the absolute maximum of 40 concurrent connections using the IIS adsutil.vbs administration script:

First you need to set the default windows script host to be the console. Do this by running the following command:

cscript //h:cscript


Next run the adsutil.vbs script from the Inetpub\AdminScripts like so:

C:\Inetpub\AdminScripts\adsutil set w3svc/MaxConnections 40


Job done!

Mark Russinovich has a great blog entry describing the Windows OS memory limits. He explains why you never get the full 4Gb on 32-bit Windows XP machine.

If you run any P2P or torrent software with Windows XP SP2 you may run in to some network performance issues. This is due to Microsoft reducing the number of half-open concurrent connections from 65,000 to 10 as part of SP2.
When the limit of 10 is reached any further connections are queued up and released by Windows at a rate of 10 per second.

This limit was introduced to reduce the speed at which viruses and worms etc using PC's can spread themselves. However the side effect means some networking applications struggle to function as intended.

Checking the Windows System Event Log will show a warning for Event ID 4226:


The Fix:
A patcher exists at
Download and run the file EvID4226Patch.exe
It will detect the version of TCPIP.SYS and tell you the current limit for concurrent half-open connections.
Pressing Y to install the patch will change the limit to 50.
You also have the option to change the limit to any value between 10 and 16777214.

After a restart the new limit will take effect.

Job done.
