Accounts locking out After installing win2008 r2 DC's

I manage a domain that is part of a forest. At the hub site, i removed the 2003 DC's and replaced them with 2008 R2 DC's. on the sites, 12 of them i still have 2003 DC'S running. Now I have an influx of account lockouts. How do i fix this? Can 2008 and 2003 work well together, Are the gpo's compatible.
ds001 is the is the pdc emulator and rid master, ds002 is the infrastructure master, bot are global catalogs.

All the accounts seem to be locking out on ds001, which was the last dc i added to the hub site
i will change the password policy and see if this works

What other roles does ds001 have?  is it the ony Global Catalog?  you can try demoting it and re promoting it.  
No, I have two global catalogs, ds002 is also a gc and infrastructure master
Ok. Try unplugging ds001 drom the net work and see if thry stop
This solution worked perfectly, THANK YOU.
