After trying to get access to a computer that we no longer had admin rights to, I decided to try using Altiris DS to create a user with admin rights (Altiris client was still installed).
Nice! I'm glad you got that working too. I suppose there are many ways to get into a system that you no longer have admin rights to. Thanks for sharing!
I would do it this way since the above, while a good solution, shows the script in plain-text. Here is a VB script you can run via DS. You can use a tool like VBSEdit to change the VBS file into an EXE which will hide the text a little better.
Const ADS_UF_DONT_EXPIRE_PASSWD = &h10000 strComputer = "." Set colAccounts = GetObject("WinNT://" & strComputer & ",computer") 'Sets username Set objUser = colAccounts.Create("user", "userguy") 'Sets password objUser.SetPassword "password1234" 'Sets Display Name of account objUser.Put "fullname", "bob kid" 'Sets description objUser.Put "description", "Windows Account" 'Sets PW to not expire objPasswordExpirationFlag = ADS_UF_DONT_EXPIRE_PASSWD objUser.Put "userFlags", objPasswordExpirationFlag objUser.SetInfo
