How to Install new patches on Windows Server 2003

[javagreen]

Okay, so I'm running a slipstreamed copy of Windows Server 2003 Enterprise. It's slipstreamed with the leaked SP1 build 1023.

Now the problem I face is that even the newer patches (like WindowsServer2003-KB835732-x86-ENU and WindowsServer2003-KB837001-x86-ENU for example) WONT install. They all give the same error...saying that the installed version of the service pack is greater.

It says this despite NOT having the particular updates I'm trying to install. Any way to get around this? Please help I don't wanna run an unpatched system
