求助：WINDBG无法找到Symbol文件

我用的是XP系统，所以装得是XP的Symbol。
在WINDBG中，我设置如下：
symbols file path设成：C:\WINDOWS\Symbols;F:\USBEX\objchk_wxp_x86\i386

结果显示：Opened \\.\pipe\com_1
Waiting to reconnect...
Connected to Windows XP 2600 x86 compatible target, ptr64 FALSE
Kernel Debugger connection established.
Symbol search path is: F:\USBEX\objchk_wxp_x86\i386;C:\WINDOWS\Symbols
Executable search path is: F:\USBEX
*** ERROR: Symbol file could not be found.  Defaulted to export symbols for ntoskrnl.exe -

有人遇到过这种情况吗？如何解决？

联网的不会，只会用KD解剖dump后的尸体
