This would not be useful to people who disable the Administrator account, but here's one way we came up with to change the Administrator account password on computers on a regular basis. Admittedly it's not the coolest or most secure method, but it's one method. :)
I've seen various methods and mediums people use to change the Administrator account: vbscript, the 'net user' command, logon scripts, GPO, etc. Using the vbscript in this method can be deployed to computers using Altiris Deployment Console, or for an automated approach, Software Delivery Solution.

'Set New Administrator Password
'vbscript
strComputer = "."
strDate = Date()
strPassword = "SamplePassword"
strUser = "Administrator"
firstSlashPos = instr(strDate, "/")
' Get the text up to (but not including) the first slash
strMonth = left(strDate, firstSlashPos - 1)
