I have a Sony Vaio VGN-FZ290 notebook computer. It is running Windows Vista Ultimate A brief summary of the system specifications are as follows: 2.2GHz Intel Centrino Duo 800MHz FSB 2GB RAM 160GB HDD Not sure any of that is actually relevant, but I thought I'd list it because this computer is not in the system specs in my profile. It does some pretty weird $h*t lately. Most of the **** can be attributed to "oh well windows just sucks sometimes." Some of it however, is just not normal, like the problem I'm experiencing now. About once every 24 hours, the computer decides that something called "Remote Procedure Call (RPC) service" has shut down unexpectedly. It's solution: Reboot the computer. Well this happens to be a problem, because it interrupts everything else that's going on. Here is the message in the event logs that it gives: Log Name: System Source: USER32 Date: 1/21/2009 3:07:43 AM Event ID: 1074 Task Category: None Level: Information Keywords: Classic User: SYSTEM Computer: Chii Description: The process C:\Windows\system32\services.exe (CHII) has initiated the restart of computer CHII on behalf of user NT AUTHORITY\SYSTEM for the following reason: No title for this reason could be found Reason Code: 0x30006 Shutdown Type: restart Comment: Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly Event Xml: <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event"> <System> <Provider Name="USER32" /> <EventID Qualifiers="32768">1074</EventID> <Level>4</Level> <Task>0</Task> <Keywords>0x80000000000000</Keywords> <TimeCreated SystemTime="2009-01-21T09:07:43.000Z" /> <EventRecordID>28480</EventRecordID> <Channel>System</Channel> <Computer>Chii</Computer> <Security UserID="S-1-5-18" /> </System> <EventData> <Data>C:\Windows\system32\services.exe (CHII)</Data> <Data>CHII</Data> <Data>No title for this reason could be found</Data> <Data>0x30006</Data> <Data>restart</Data> <Data>Windows must now restart because the Remote Procedure Call (RPC) service terminated unexpectedly</Data> <Data>NT AUTHORITY\SYSTEM</Data> <Binary>06000300</Binary> </EventData> </Event> I have been attempting to read up on this error, and the only thing I've come up with, is that there's this thing that apparently affects XP called a w32.blaster.worm or something. Now, even if that can affect vista, I don't think it's here, because the symantec removal tool for it, and it says that it isn't on the system. Any ideas how to stop this from happening?
