Hi all, I've been searching around on the forums with little luck for a topic similar to mine. Heres the issue, doing unattended installs of XP Pro, and I have a batch process that runs wsname and restarts and then joins the domain. the domain join us a runonce task, I'm using a autoitscript thats doing WMI? commands (The script was pulled from the autoit User submissions. It was basically a GUI LDAP browser with a join domain, I just stripped out the GUI bits). The Autoit WMI is returning error 8525 on SOME machines (seems repeatable, once I get it on a machine, I will allways get it on the same machine). I haven't had any luck figuring out exactly what that error is. So I started poking around on the machine, and I noticed the netbios name is different than the computer name. I checked the wsname log file, and it thinks everything is fine. I am unsure if I am even barking up the right tree with thinking I'm having problems with wsname. The only thing I have that indicates issues with the computer name, if I tried to join AD by hand, it would generate errors. A popup that says the name change failed (name was all ready changed, it was just a join ad at this point), and then some event viewer errors, 5788 & 5799. "Attempt to update HOST service Principal Names (SPNs) of the computer object in the Active Directory failed. The updated values were 'HOST /071PBRKJT21' and 'HOST /OED-3FFFd908464'. The following error occurred: The parameter is incorrect." The OED-* is the randomly generated name from the unattended, and currently the netbios name of the PC in question. I've searched for those event ID's and they don't seem to make a whole lot of sense in the fact it works on some, and fails on others. Should I be waiting for certain processes or services to start before I attempt to do the rename? Any ideas anyone can think of? My goal here is to have a computer renamed to a section number + serial number and then a successful join domain.
