(http://support.microsoft.com/kb/256986/ )Description of the Microsoft Windows registry
The Svchost.exe process intermittently crashes with an access violation when the process uses the Wininet.dll file on a Microsoft Windows XP-based computer.
This problem may occur when a service loads and unloads the Wininet.dll file many times. This behavior may occur when the Wininet.dll file cannot open the cached index file. Then, the Wininet.dll file may try to unload the index file and fail with an access violation because the pointer to the index file is NULL.
