We have a script that automatically adds a freshly imaged computer to the domain. The functionality of joining the domain is always successful. However, when the script attempts to add the domain groups, it fails 50% of the time. Below is the script. I didn't write it, I just have to figure out why it is failing. I replaced company identifying information. Any ideas?

So you want to add some groups to the local administrators group? Why don't you use a GPO for that? You can find it in: Computer Configuration -> Policies -> Windows Settings -> Security Settings -> Restricted Groups. –  ZEDA-NL Mar 27 '12 at 13:01
    
Normally you need to reboot in order to join a domain, so I'm amazed this works even 50% of the time. –  Harry Johnston Mar 28 '12 at 2:10
    
@ZEDA-NL I am going through group policy to replace this script when we implement Windows 7 throughout the company. It is in testing right now and has 100% success but the management team is not confident in allowing me to use it because 10 years ago they did the same thing (incorrectly) and locked everyone out of the entire domain because they accidentally removed all admins instead of just adding them. –  Kevin Shoaf Mar 28 '12 at 20:15
    
@Harry Johnston Amazingly, it used to work 100% of the time. I don't understand why that changed. –  Kevin Shoaf Mar 28 '12 at 20:16

It looks like the actual work is done by the unfortunately named "jdom" script, and that's probably where the trouble lies, not in this code. –  Harry Johnston Mar 28 '12 at 20:41

it's probably that line that says wscript.sleep(30000). I'd bet the times it fails is because the script resumes execution before the computer is added to the domain. an obvious patch / test would be to up the wait time to a minute or so, but it's less than optimal. maybe something like what zeda proposes in the comments is a better solution. Still, upping the wait time should work as a patch

Actually, the wait time was added when the issue started. We've upped it to 15 minutes and it still occured. –  Kevin Shoaf Mar 28 '12 at 20:13

We took out the group additions and went with group policies. We found the issues with the groups being added via script to be latency in the domain controllers. Until it can be resolved, there was no solution other than group policies, which it should have been to begin with.
