虽然说是针对xp的,但是2003上也一样能成功,有空再来写翻译

This article only applies to WinXP SP2. If you have not already got SP2, but you do have Win XP, consider upgrading. There are numerous issues concerning BITS on Windows 2000 and lower; see [3,4] for further details.
Run the following command:
```
%windir%/System32/rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%/inf/qmgr.inf
```
If you are prompted to insert your operating system CD, type the following path in the Copy files from box, and then click OK:
```
%windir%/ServicePackFiles/i386
```
Restart your computer, and try to manually start the BITS service. If it still fails, try step 3.

Run the following command:

Reg add HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/BITS/Parameters /v ServiceDll /t REG_EXPAND_SZ /d %windir%/System32/qmgr.dll

Restart your computer, and try to manually start the BITS service. If it still fails, try step 4.

Run the following command:
```
Reg add HKLM/SYSTEM/CurrentControlSet/Control/BackupRestore/FilesNotToBackup
```
Restart your computer, and try to manually start the BITS service. If it still fails, try step 5.

Run the following commands [6]:

regsvr32 oleaut32.dllregsvr32 jscript.dllregsvr32 vbscript.dllregsvr32 msxml.dllregsvr32 softpub.dllregsvr32 wintrust.dllregsvr32 initpki.dllregsvr32 cryptdlg.dll

Restart your computer, and try to manually start the BITS service. If it still fails, try step 6.

Delete the following directory [6]:
```
C:/Documents and Settings/All Users/Application Data/Microsoft/Network/downloader
```
Restart your computer, and try to manually start the BITS service. If it still fails, try step 7.
Place a valid original Windows XP CD in the CDROM drive and run the following command [6] (taken from [10]):
```
sfc /scannow
```
The command may take a long time, up to an hour, to complete, as it checks the integrity of each system file [11]. Restart your computer, and try to manually start the BITS service. If it still fails, this article cannot help you further, and you should contact MS Support to resolve the issue [3,4]. Other links you might like to investigate are [7,8].

Remember to set the service starting default to "automatic" rather than "manual" once the issue is resolved.
