PXE WDS Failure on Distribution Point

[aknott]

Hello All,

I own a configuration using a CAS, 4 Primaries and several DP linked to primaries.

EDIT: Using SCCM 1802 (but this issue occured around 2 month ago when I used 1710)

the schema is the following

	CAS
PRI1	PRI2	PRI3	PRI4
DP1		DP8
DP2
DP3
...
DP7

 

since few weeks I have issues on 3 DP (and only on those 3 ones)

those 3 DP are linked to the same site Code. (in the schema let assume they are DP2, DP3 and DP4)

the error in smspxe.log are the following

failed to receive response with winhttp; 80072f78
Unsuccessful in getting MP key information. 80072f78.
PXE::MP_InitializeTransport failed; 0x80072f78
PXE::MP_ReportStatus failed; 0x80070490
PXE::CPolicyProvider::InitializePerformanceCounters failed; 0x80070002

those  errors lines occurs 3 times then wds is started BUT it is not running well. No client can pxe boot.

I checked a lot of parameters,

I did a lot of tests on those DP

1. disable PXE, remove wds, enabled PXE (wds automatically setup) -> FAILURE

2. disable PXE, reboot, install manually WDS, enabled PXE -> FAILURE

3. tried on differents OSes (2012R2, 2016) ->FAILURE

the only succes I got is to link one of those DP to another Site Code (so to another MP) in that case it works

if I create new server  on the same AD site where is DP3 then  I create a distribution point on this server (DP9) but connected to PRI2 then in this case it works.

I could think the error is on the MP (PRI1) BUT all other DP attached to this primary site code are running well.

I did a lot of search on internet, tried to check network, disabled firewall and AV on both sides with no luck

the main issue seems to be regarding of the 80072f78 error CODE (first line)

this seems the MP is not responding to the DP but If, from the DP i do several checks like using IE and go to

http://PRI1.domain/sms_mp/.sms_aut?mplist   I get right information

http://PRI1.domain/sms_mp/.sms_aut?PKEYINFORMATIONEX   I get right information

 

I 'm starting to running fool with this issue.

if someone can lead me to the right way I would be very gratefull
