Apple AirPrint via iPads & iPhones

Airprint is a new feature part of Apple’s IOS 4.2.1 that allows you to print from your IOS device to an airprint compatible printer (see list below).

For an IOS device to be able to print to this printer via Airprint, the printer and the IOS device needs to be connected to the same WiFi network. Printing from PC and MAC seems to work easily for me, but printing from the iPad caused problems when I tried to print, and select a printer, no printer was found.

At work we had a Cisco wireless network, and eventually to get it to work we had to enable a feature called “Multi-Cast Forward” on the wireless router.  All 3 of our printers were now discoverable and we can print via Airprint.

Default Domain for Windows Server

Usually when you remotely connect to a Server Desktop either via RDP or Citrix, the default Domain should be your domain, sometimes the server name appears instead. To change the server to display the domain as default you can either log onto the server’s console (or mstsc /console or mstsc/admin) with your domain account, then log off or you can make the following registry change on the server

HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\DefaultDomainName

Extending disk space C: drive on a Windows 2003 Server

Sometimes when you run out of space on a server, you want to add more disk space.

You will need to add another drive or expand the disk (virtually) where you will have free unallocated disk space.

On the windows server, there is a utility called diskpart, instructions on how to use is is below

In some circumstances you will get an error ““The volume you have selected may not be extended”

Another tool that I’ve found that can overcome this error is

it works on Dell servers as well as Virtualised servers.

Another site with good instructions using a different method can be found at:

How to determine the type and where the Citrix datastore is located

Investigate the properties of C:\Program Files\Citrix\Independent Management Architecture\MF20.dsn.

The following is an example of an MF20.dsn file from a server using an Access data store on the local machine:

For a MS Access database datastore:


DRIVER=Microsoft Access Driver (*.mdb)
FIL=MS Access
DBQ=C:\Program Files\Citrix\Independent Management Architecture\MF20.mdb

For a SQL database datastore:


APP=Citrix IMA

If the MF20.dsn file is not present, it means the server is doing an indirect connection to the data store. Check the value of server with the direct connection to the registry under:


Check the MF20.dsn on that server.

For Access data stores, only one server in the farm (the one hosting the data store) shows imaacces.dll under: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\IMA
