strange dsconfigad problem in 10.4.11

Anyone seen this??
I work at a college and we manage ~1000 Macs of various shapes and sizes. When we image a machine we have a script that joins the machine to our Active Directory Domain, we just rewrote the script when Leopard came out so it worked with both our Tiger and Leopard images. Now in the latest version of our Tiger image, where the only thing changed was apple updates and 10.4.11, the script only works about 10% of the time.
I’ve narrowed the problem down to the dsconfigad command, it executes and then just hangs. Now it’s used 5 times in the script, and it doesn’t always hang at the same one every time, it usually gets through the first execution, but not always, and then hangs at one of the following executions, but kind of randomly which one it picks. And then occasionally it makes it through the whole thing. The script still works great on the 10.4.10 Tiger images and also on the Leopard images.
I’ve tried everything I can think of to fix the problem with no luck. The only thing that I’ve seen that looks kind of funny is when I put DirectoryService into USR2 debug mode, there are some dsDoPlugInCustomCall() errors with result -14260. But those are there when the script doesn’t hang too.
So I’m stumped, anyone know if they changed dsconfigad or DirectoryService with 10.4.11?? I saw the post about buggy AD plugin and SMB and I wonder if this is part of the same issue? Any help is greatly appreciated.
