Windows 2003 - harddrive light on non-stop

[geist4]

I seem to have an issue with one of my DC/DNS servers that I can't pinpoint the problem or solution. The details are as follows:

I start seeing the event error 1058 on this server. (Windows can't access a group policy object - access is denied.)I have already worked through the trouble shooting in the folowing MS-KB Articles:

887303,830676,842804,842804,822158,815263,887429

Everything checks out ok. (I did find that my Antivirus exceptions were not configured. This has been corrected but it did not correct the problem. See:MS-KB 822158)

I have checked the System monitor for the hard disks and they very on the %Disk Time Counter from 0%-90% average 30%.

I ran Dr. Dos hard disk utils to check the health of the drives and they check out ok.

After I reboot the machine the hard disk light activity returns to normal and all the counters return to below 30%.... After about two weeks from the reboot the hard drive light will come on again and stays on.

These problems seemed to have started about a month after installing the last service pack and using the security configuration wizard.
