Hello, I am getting a lot of Event ID 23 un my System Event Log: Log Name: system Source: Eventlog Event ID: 23 Level: Error User: LOCAL SERVICE The computer is joined to a Win2K3 R2 domain. The problem is in all Windows 7 computers joined in the domain. I think there is some issue with LOCAL SERVICE rights in the Windows 7 computers but I cannot find what is the error. Windows 7 computers cannot connect to network, start some services as "Diagnostic Policy Services" cannot be started because Access Denied error (Diagnostic Policy Service is started under LOCAL SERVICE ACCOUNT). Also I am having a lot of issues with network connections and certifiacte error when I am browsing in internet. Regards, Patricio

Thanks for your reply! My responses: 1. I wasn't enable to get DHCP address from the DHCP server. I fixed this unjoining the computer form the domain, deleting the computer account, creating a new OU with blocked GPO inheritance, then creating a new computer account inside this OU and finally joining again the computer in the domain. It apear that there is something in the GPO that only affects to Windows 7 computers bt I didn't find what is. The certificate errors appears on Event log as event id 4110. The symptom is that every page that has certificates is showed as non trusted because the certificate cannot be verified in a root authority. This happens with every browser (I tested with IE 8, Firefox and Chrome). the event details are: - <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> - <System> <Provider Name="Microsoft-Windows-Eventlog" Guid="{FC65DDD8-D6EF-4962-83D5-6E5CFE9CE148}" /> <EventID>23</EventID> <Version>0</Version> <Level>2</Level> <Task>100</Task> <Opcode>0</Opcode> <Keywords>0x8000000000020000</Keywords> <TimeCreated SystemTime="2009-08-27T13:36:19.726378700Z" /> <EventRecordID>191204</EventRecordID> <Correlation /> <Execution ProcessID="848" ThreadID="2620" /> <Channel>System</Channel> <Computer>PATRICIOWIN7.envision.cl</Computer> <Security UserID="S-1-5-19" /> </System> - <UserData> - <InitChannelLoggingFailure xmlns:auto-ns3="http://schemas.microsoft.com/win/2004/08/events" xmlns="http://manifests.microsoft.com/win/2004/08/windows/eventlog"> <Error Code="5" /> <ChannelPath>Microsoft-Windows-WPD-MTPClassDriver/Operational</ChannelPath> </InitChannelLoggingFailure> </UserData> </Event> 2.
