I figured out how to do it:-
When the user selects the browse button the code I sent previously is
run and sets the LFM_SERVER_ROOT property. I then publish a property
change event as described on MSDN
(http://msdn.microsoft.com/en-us/library/aa371695(VS.85).aspx) and the
control I want to change subscribes to this event and the text will be
updated. I noticed that if you changed the text in the control before
running the custom action then the update didn't work so I have disabled
it so the user can only change it via the custom action, which is okay
in my scenario.
<Control Id="Browse" Type="PushButton" X="260" Y="88" Width="65"
Height="15" Text="&Browse..." TabSkip="no">
<Publish Event="DoAction" Value="NetworkBrowserDialog" >1</Publish>
<Publish Event="[LFM_SERVER_ROOT]"
Value="[LFM_SERVER_ROOT]">1</Publish>
</Control>
<Control Id="MachineName" Type="Edit" X="57" Y="67" Width="270"
Height="16" Property="LFM_SERVER_ROOT" TabSkip="no" Disabled="yes" >
<Subscribe Event="LFM_SERVER_ROOT" Attribute="Text"/>
</Control>

Hi,
I do tie the control to the LFM_Server_Root property, but it still
doesn't update.
What I want to do is on a button click fire a custom control. Within
that custom control set a property and when the custom control has
finished I want this value to appear on the dialog that the button was
pressed on. Any ideas?

MSI supports updating a control "live" only for the property it's tied
to.
