Network Name is here:
System Preferences / Sharing / Computer Name
eg  Lawrence’s MacBook
Write it down, we’ll need it in step 2.
Mac Address is here:
System Preferences / Network –  Ethernet / Ethernet
eg
mac address – 00:1b:00:99:cd:1a
Write it down, we’ll need it in step 2.
2) Create a Time Machine Empty Backup file in Terminal
Open up Terminal
Spotlight-> Terminal
Change to the root folder.
cd /
We’ll need to paste this into terminal -
hdiutil create -size 300g -fs HFS+J -type SPARSEBUNDLE -volname “COMPUTER NAME” “COMPUTER NAME_MACADDRESS.sparsebundle”
Replace COMPUTER NAME and MACADDRESS with the ones from step 1. The MACADDRESS needs to have bypass surgery to remove its colons.
eg:
My computer details are
Computer Name: Lawrence Sheed’s MacBook
Mac Address: 00:1b:00:99:cd:1a
So my line would look like this:
hdiutil create -size 300g -fs HFS+J -type SPARSEBUNDLE -volname “Lawrence Sheed’s MacBook” “Lawrence Sheed’s MacBook_001b632eb218.sparsebundle”
3)  Copy file to the network share in root folder \
Once you have the file created in step 2, copy that file to the Network Share where you want to use Time Machine.
The backup file needs to go to the root folder \ on the share.
4) Configure Time machine to allow use on network shares
(in terminal)
defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1
4) In Time Machine, point to the drive.
System Preferences / Time Machine
Choose the network drive..
It will now allow you to backup to the network share.
Tested and working in 10.5.5 Leopard.
Thats it!
