Hi everyone,

We're write you for some assistance.

We have a SCCM server in our company and we want to deploy windows 10 S.O trought PxE in our clients, using a DP. The SCCM is in a different subnet than the DP and the clients. DP and clients are in the same one.

After configure the SCCM, DP and DHCP we tesdted the deployment with 2 blank VM (Gen 2) deployed in a HYPER-V node .

The WDS Boot Manager connected the client to the DP and the configuration manager wizard deployed the O.S correctly.

In first place, appears the Contacting server message (this doesn't appear in the deployment with VMs)

After several minutes we get a timeout error:

In the traffic snnifing in the SCCM server we can see a tftp transmission between the client and the SCCM server (NOT the DP)

When the TFTP transmission finishes we can see a lot of proxyDHCP Request not responded that finally procude the time out error:

In the server with the DP role sniffing, no traffic appears for the client IP.



In the VM deployment sniffing, we saw traffic between SCCM and the client but all the tftp traffic was between DP and the client. The proxyDHCP Request was responsed with the DP ip by the SCCM server.



Can someone assist us with this?

Many thanks in advance!!
