.... usually requiring server reboots. Windows 2003 Server Enterprise
R2. SP 2. Single server environment with Exchange as well.

Started Monday night. Clients start loosing access to shares and then

Event 1030

"Windows cannot query for the list of Group Policy objects. Check the
event log for possible messages previously logged by the policy engine
that describes the reason for this."

and

Event 1058

Windows cannot access the file gpt.ini for GPO
CN={6AC1786C-016F-11D2-945F-00C04fB984F9},CN=Policies,CN=System,DC=<doman
redacted>,DC=local. The file must be present at the location <\\<doman
redacted>.local\sysvol\<doman redacted>.local\Policies
\{6AC1786C-016F-11D2-945F-00C04fB984F9}\gpt.ini>. (Configuration
information could not be read from the domain controller, either
because the machine is unavailable, or access has been denied. ).
Group Policy processing aborted.

Unfortunately, none of the fixes apply. I am on the current SP. And
none of the workarounds are doable (ICF/ICS or RRAS are currently not
enabled. NAT driver is already disabled).
