I converted my main workstation at home to a virtual machine, and started connecting to it via RDP from a thin client machine. I found that images didn’t look quite right, and had banding instead of proper gradients. The color depth was set to 16-bit and couldn’t be raised, even when setting the depth higher using the RDP client.

Remote Desktop server on Windows XP, by default runs at a maximum 16-bit color depth. However up to 24-bit color is supported. Read the rest of this entry »

Every now and then I will be multitasking and will move the Show Desktop icon off the Quick Launch toolbar.  Sometimes clients will delete this icon not realizing how much they actually use it.

To replace it open Notepad and enter the following text:

[Shell]
Command=2
IconFile=explorer.exe,3
[Taskbar]
Command=ToggleDesktop

Save the file as ‘Show Desktop.scf’ and place it in the ‘%userprofile%\Application Data\Microsoft\Internet Explorer\Quick Launch’ folder.

I was unable to add x64 print drivers (for distribution to 64bit clients) on a 32bit Windows Server 2008 install.  This is the workaround:

1. On an x64 machine browse to \\servername, where servername is the x86 print server.  (Start -> Run…, type ‘\\servername’.
2. In the list of shares, open the Printers folder.
3. Right-click in the Printers folder and select Server Properties.
4. Go to the drivers tab and add a new x64 driver.

The other day, by chance, I came across the built in status bar quota usage display.  I had accidentally set the storage limit on one of my mailboxes to ‘null’.  In turn Thunderbird presented me with a red bar warning me that I was way over my quota.

Today, I decided I wanted the usage to display on my IMAP accounts at all times.  This is what needs to be done:

1. In Thunderbird go to Tools -> Options…
2. Select the ‘Advanced‘ panel, under the ‘General‘ tab, click the ‘Config Editor…‘ button.
3. Find the following setting:  ’mail.quota.mainwindow_threshold.show‘ and set it’s value to ‘0‘

Thunderbird needs to restart for this setting to take effect.

Additionally, there are options for setting the Warning and Critical thresholds.  These cause the precentage bar to change to yellow and red.

mail.quota.mainwindow_threshold.warning
mail.quota.mainwindow_threshold.critical

I recently setup ISPConfig 3 RC2, on an Ubuntu 8.04 server following the install instructions provided on the ISPConfig site.  I did however experience an issue with inbound mail being rejected for valid mailboxes with the following error:

Action: failed
Status: 5.1.1
Diagnostic-Code: x-unix; ERR: authdaemon: s_connect() failed: Permission denied
Invalid user specified.

This was resolved by changing the ‘maildrop’ line in ‘/etc/postfix/master.cf’ to:

flags=R user=vmail argv=/usr/bin/maildrop -d vmail ${extension} ${recipient} ${user} ${domain} ${sender}

The following may also be required to fix this error:

chmod 4755 /var/run/courier/authdaemon
