SCCM PXE boot failed after unintall WSUS.

NOTE: I moved to

Setup my test lab in this weekend to test SCCM TP 1609, and my PXE boot failed. SMSPXE.log shows:

RequestMPKeyInformation: Send() failed.
Unsuccessful in getting MP key information. 80004005.
PXE::MP_InitializeTransport failed; 0x80004005
PXE::MP_ReportStatus failed; 0x80070490,
PXE::CPolicyProvider::InitializeMPConnection failed; 0x80070490


When tried to open MP list, http://my_sccm_server/sms_mp/.sms_aut?mplist, it gave me HTTP Error 500.19

Error Code 0x800700e, unable to load DLL.

So what happend? Well, because I uninstalled WSUS (not ask my way, I had my reason. 😀 ), applicationHost.config files didn’t updated itself.

How to fix it:

Open “C:\Windows\System32\inetsrv\config\applicationHost.config”, search “suscomp.dll”, and remove the whole line.
Problem soveled.

<scheme name="xpress" doStaticCompression="false" doDynamicCompression="true" dll="C:\Program Files\Update Services\WebServices\suscomp.dll" staticCompressionLevel="10" dynamicCompressionLevel="0" />


Well, you can also install WSUS back, it will fix the problem for you. 🙂
