mrdk83 Posted November 24, 2014 Report post Posted November 24, 2014 I'll try to re-install the MP. Whether such operation may cause some problems? I have a question about ports. Client to communicate with the MP and download the policy needs to be open only port 80? And what about the port 135? Is it required that the client can retrieve policy?

mrdk83 Posted November 26, 2014 Report post Posted November 26, 2014 Clients for some time worked properly. At some point, they stopped to communicate. After analyzing the logs I noticed that there is a problem with the registration of clients.Clients of the subnet in which the server sends to the SCCM CCM_POST to /CCM_SYSTEM/request gets a 200 OK response and communication occurs.You can see it in the screenshot:https://onedrive.live.com/?cid=9b412d54c4539175&id=9B412D54C4539175%2112903&v=3&ithint=photo,jpg&authkey=!AC1SSE0BRRxiXr4 In other subnets client has a problem with communication. After sending CCM_POST gets a response from the IIS server with error 400.

mrdk83 Posted November 27, 2014 Report post Posted November 27, 2014 Problem solved. This was caused by a badly configured on the router filtering service HTTP headers. Quote Share this post Link to post Share on other sites More sharing options...
