RemoteApps are black windows on a Windows 2008R2
by lunarg on September 19th 2012, at 12:48
When running some RemoteApp, published from a Windows 2008R2, you may sometimes experience that the application does not start properly. In the startup window, when clicking on the Details button, you see a black window and no contents at all. The problem mainly occurs when working via internet, via a wireless network, or some other slower-than-normal link. Additionally, when your session is logged off on the RDS server, you will be able to start the RemoteApp once; subsequently restarting the application results in the above specified behaviour.

The issue is caused by the Remote Desktop Session Host display driver on the RDS server. During the initial connection, the monitor layout packe  ...
 
View/edit/export Outlook AutoComplete information
by lunarg on September 18th 2012, at 10:38

NirnSoft has a useful tool to view, edit, import/export Outlook AutoComplete information.

http://www.nirsoft.net/utils/outlook_nk2_edit.html

It can handle all versions of Outlook that support this feature, as well as the the information stored in a message store (be it Exchange or local PST).

 
Exchange: move mail to a folder depending on which alias it's sent to
by lunarg on August 24th 2012, at 10:34

Currently, Exchange/Outlook only supports client-side rules if you want to move messages to a specific folder, depending on which alias it's sent to. This means that the rule only works when Outlook is running, which is not always possible.

You can workaround the issue by creating a rule that checks for the content of the message headers. This type of rule can be created server-side and will always run when messages arrive on the Exchange server. By checking whether the alias is present in the message headers, you can easily create a rule that moves those messages to another folder.

 
MySQL replication error 1236
by lunarg on July 6th 2012, at 14:06
Two possible occurences may happen related to this error 1236: either you get the error message like so:

Got fatal error 1236: 'Client requested master to start replication from impossible position' from master when reading data from binary log

Or, no error is given and the Slave_IO_Running is returning no while the Slave_SQL_Running returns yes.

If this occurs, it may be because the master went down unexpectedly (and has since rebooted). Because of this, the slave has not received the command to switch to the next binlog file and is stuck at the previous one.

In other cases, it's possible that no error is displayed, but that the Slave_IO_Running still says no. In this case, the master   ...

Trapeze: MAC-based authentication gets ignored after correct set up in Ringmaster
by lunarg on July 6th 2012, at 11:49
At a client running a Trapeze/Juniper network with some MX-8 controllers, a bunch of MP-371B and an instance of Ringmaster software to control and configure it all, we were working on implementing MAC-address based authentication for one of their ESSIDs. After correctly setting up the necessary policies, and AAA servers, we noticed that any client could still connect to our network, despite all settings being correct.

Baffled at this, we started to look around, trying to figure out what went wrong. My collegue finally remembered the true cause for our problem, a setting in the Wireless Service Profile.

There, the Fall Through Access was set to last resort, which basically tells the network  ...
 
Reset the ARCserve 'caroot' password
by lunarg on July 6th 2012, at 11:32
If you lost or forgot your CA BrightStor ARCserv password, you can do the following to recover it.

Open cmd.exe, and navigate to the root of your ARCserve installation (e.g. C:\Program Files\CA\BrightStor ARCserve Backup\).

Once in the root of the ARCserve folder, type cstop to stop all running ARCserve services.

Use Windows to navigate to the sub-folder \Data\Discovery (e.g. C:\Program Files\CA\BrightStor ARCserve Backup\Data\Discovery). In there, you'll find a folder that bears the name of your server. Rename this folder (e.g. append ".old").

Back in the command prompt, type cstart to start the services again.

Run the command Authsetup /p "password" where "pas  ...
 
Shadowing a Windows 2008 Terminal Services session results in disconnection
by lunarg on July 2nd 2012, at 18:02

When running a Windows 2008 (R1) Terminal Services, and you connect with a RDP 7.1 client and try to shadow another session, it may happen that both clients get disconnected.

KB2523307 tells us that this is caused by RemoteFX being active when a new client is used.

A hotfix is available to address the issue, and can be requested via the KB.

EDIT: for your convenience, I've attached the hotfix (English only!), at least until Microsoft requests its removal...

 
Remote Desktop Server lock-down guide
by lunarg on July 2nd 2012, at 17:19
This article is a reference to a number of articles and links to provide information about how to succesfully lock down your Remote Desktop Server (2008R2) or Terminal Server (2003 / 2008). It is not a definite guide to how to perform a lock down, but will provide certain pointers, and highlight certain pitfalls. It is a work-in-progress and several additions will be made as the guide progresses.

You obviously need a Windows-domain running AD for lockdown to work properly. A standalone server running a local group policy can't be locked down enough to be useful. A domain is highly recommended.

Your DC or a member server (can be the RDS / TS as well) should have the Group Policy Mana  ...
 
Always show Computer icon on desktop
by lunarg on July 2nd 2012, at 17:18
To always show the Computer icon on the desktop via GPO, there are several things to be set. Aside of the obvious setting in GPO, you also have to add a registry entry through GPP to automatically show the Computer icon on desktop.

In User Configuration, Preferences, Windows Settings, Registry, add a new entry. Whether you want to enforce or not, is up to you. Either choose create (only applied once), or Replace (always apply).

The value is a DWORD value in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons\NewStartPanel, named {20D04FE0-3AEA-1069-A2D8-08002B30309D}. This is the CLSID for the Computer icon. Set it to 0 to have the icon shown on user's des  ...
 
Change duration of Windows 7 Desktop Slideshow animation
by lunarg on July 2nd 2012, at 15:36

When using Desktop Slideshow in Windows 7 (a slideshow of desktop backgrounds), you can change the duration of the transition between two images with a registry hack.

  1. Navigate to the key HKEY_CURRENT_USER\Control Panel\Personalization\Desktop Slideshow
  2. Create a new DWORD (32-bit) value, named AnimationDuration. The value of this DWORD is set in milliseconds. Setting it to 2000 will produce a transition of 2 seconds, and so on.

Aero mouse cursors in 2008/R2 server editions
by lunarg on July 2nd 2012, at 13:14
By default, the Aero mouse cursor theme was left out of the server editions (2008, 2008R2 and their SBS counterparts). For those that wish to have these cursors available on their server (e.g. if you want the "full" desktop experience on a RDS/TS server), I've compiled an archive with the necessary files and registry entries. They come from a Windows 7 Pro but are usable on all server editions (2008 and up). Note that you can easily get them yourself off a Vista or Windows 7 install by copying the right files and exporting the right registry key and values.

Inside the archive you'll find a cursors folder. Copy the contents of that folder to %windir%\Cursors . If you get an overwri  ...
 
Remove links from the Games menu
by lunarg on July 2nd 2012, at 12:54

You can remove (or manage) links in the Games menu through the registry. The key for this can be found at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\GameUX\Games.

For each entry there's a subkey named a CLSID. When browsing through the list, opening a CLSID reveals the actual title, path and some other settings of that entry. If you want to remove an entry, find the right entry by checking titles and/or paths, then delete that key.

 
XMeeting, a working SIP client for Mac OSX
by lunarg on June 22nd 2012, at 16:14
Free (as in "beer") SIP clients are very scarse on the Mac OSX platform. Most clients are too far outdated and only work on old versions and on PowerPC. Other, more recent clients start up but they lack proper quality and functionality to be even remotely usable.

Luckily, there is a client available. Originally designed as meeting software using the H.323 protocol, it also implements SIP and can be used with any SIP provider, including Asterisk. The client is called XMeeting, and while it's no longer actively maintained, it still runs on Mac OSX up to 10.7 (Lion).

I've tested it out at work on our Asterisk server and it works flawle  ...
 
Expired Avast subscription kills Exchange Information Store

Exchange 2010 with Avast disrupts Transport Service
by lunarg on June 22nd 2012, at 16:00
We updated Avast to the latest version on a client's server running SBS 2011. The update apparently included antispam. All of a sudden, the Transport service kept failing, and all messages (in both directions) landed in the Poison Queue. Restarting the Transport service did not fix the issue, and there was nothing we could do.

Googling around, we found that the trouble was indeed related with Avast. Disabling the Antispam Shield did not resolve the issue, but disabling the transport agent in Exchange, via Powershell was the fix:

disable-transportagent "avast antispam for exchange"

After disabling the agent, everything came to life again.

@ Avast: you should really start  ...
 
Slow printing in Adobe Acrobat
by lunarg on June 20th 2012, at 13:56
One of the more recurring issues is slow printing of PDF files in Adobe Acrobat. While Acrobat itself works smoothly, printing sometimes comes to a complete halt, taking up to 10 minutes (or even more) per page to print. The more complex the PDF document becomes, the more apparent the problem becomes.

By default, Adobe prints to your printer using PS commands, which then get converted by the printer driver to a language your printer understands (PCL, PS, HPZL, HPGL, ...). More complex PDF documents, i.e. PDF's with lots of objects, a lot of embedded fonts, damaged images, etc., generate more and more complex commands, resulting in spooler files that are a multiple of the original document,   ...

I had a hard time finding the right drivers for a Canon PIXMA iX 4000 printer for Windows 7. The drivers available on the european website are old and missing 64-bit support. After googling around, I found the drivers on the asian website. Because I lost quite some time searching for them, I thought I just post the direct links here:
