If you're talking about a service trying to read...what object? I guess I'm missing what the AD has to do with the object in question. The best tools I've found for reading object access is filemon and regmon, and procmon, all from sysinternals. That normally gives a good overview of what's working and what's not for permission access.
We do have instances of AD policies not being read by systems periodically, and the only thing that seems to work is to:
A) reboot. It might read it next time.
B) force a refresh of the policy. It seems to be random as to when/how it takes, though, and Windows is simply FANTASTIC at giving feedback on what's happening. Ha ha!
C) work around it. For example, assigning printers to certain computers wouldn't work sometimes and would other times, so eventually we just started slapping the freeware AdPrintx on to each workstation we deploy with a batch file in the startup folder that adds default printers while bypassing the random frustration of AD.
