I've been browsing this forum to find an answer for my SCCM client issues, but I cannot. At present, some computers I am working on will not communicate with the MP, but others will. They all have the same Firewall policies set by GP. I've cycled the certificates and restarted as well. When installing with the following command line: CCMSETUP.EXE /mp:<MP> /native SMSSITECODE=<SITE> FSP=<FSP> SMSCACHESIZE=10000 PATCH="\sccm2007ac-sp2-kb977384-x86-enu.msp" The install fails with an error "Failed to receive WinHttp response. (Error at WinHttpReceiveResponse: 12175)." I am able to navigate to https://<MP>/ through a web browser. When I remove the /mp: parameter, the SCCM client installs successfully, but only has "Machine Policy Retrieval & Evaluation Cycle" and "User Policy Retrieval & Evaluation Cycle" available under the Actions tab (which don't actually function) and no Updates tab. In addition, the CcmExec log displays an HTTP Error: HTTP ERROR: URL=http://<MP>/ccm_system/request, Port=443, Protocol=https, SSLOptions=31, Code=12175, Text=ERROR_WINHTTP_SECURE_FAILURE Any further steps you can suggest or more information please let me know.
