To get started we will need an Windows XP system that has been configured to receive automatic updates and the Windows 2000 system we are trying to update. Then we need to install the below updates
- Service Pack 4 and Update Rollup 1 for SP4
- Internet Explorer 6 SP1
- Root Certificate Update
- Windows Update Agent 7.6.7600.226
Note: the updates can be obtained from this toolkit
Next, go to the XP system and run the proxy. The command prompt windows needs to stay open. Now lookup and record the IP address of the XP System
Back on the Windows 2000 system we need to add the below registry keys
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
add String Value "WUServer" with a value of "http://{IP ADDRESS FROM XP SYSTEM]:8530/?"
add String Value "WUStatusServer" with a value of "http://{IP ADDRESS FROM XP SYSTEM]:8530/?"
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
add DWORD "UseWUServer" with a value of 1
With the proxy still running on the XP system we can now open the Windows Update Mini Tool on the Windows 2000 system and check for updates. If successful we will have a list of available updates to install
