Clients using wrong MP

[RahamimL]

Hi all,

I have SCCM 1810. 1 SCCM site, 1 domain and a branch office in WAN with MP, DP and PXE enabled

For some reason both LAN and WAN WinPe clients are using the WAN management point instead of the one close to them.

I checked my boundary groups and it looks Ok. My TS are deployed as available to be able to choose the right one. from smsts.log I see that it always connects to the WAN MP: clibsmsmessagewinhttptransport send winhttpopenrequest URL "WAN MP".

The Client downloads what it needs from the correct DP, but when the images finish the time is set to the WAN MP (we have 7 hours differential) even though the time zone is correct.

I added another boot image and set it so each MP is using a different boot image. and made sure that my boundary groups are OK and it looks like the time problem went away, but I still have the with how the client uses the MP...

I found somewhere that the WinPe is using an MP list which means that it if my WAN server's name is A and my LAN server name is B it will always use my WAN server...

This can't be right, right?

P.S.

We use all discoveries except network one (don't know if it's related...)

please can you share your SMSTS.log 

you will find inside the query for MP. 

what Kind of Boundary you use ?

I have uploaded the file.

I didn't see any query for MP in the log by the way.

I use both IP range and AD site boundaries that are being used within a boundary group.

Thanks

Have you placed the MP,DP etc in the boundary group?

Claus probably found my problem and there is no way around it.
Basically when a client boots to WinPE it searches via DNS for a management point. Because my remote management point is the first one to be discovered (server name) in the DNS the client will talk to it.
I think my workaround, using 2 different boot images, 1 for each AD site will minimize the issue.
If anyone can confirm this that'll be great.

Have a look at this post to manage MP's during WINPE.

Look at this post, https://social.technet.microsoft.com/Forums/en-US/226affab-deaf-4d1b-94fb-87908d17b054/choose-the-ri...

One person mentions changing a regkey.

Be careful as it might not be supported.

Better solution based on your first suggestion. In PowerShell:

$tsenv = New-Object -ComObject Microsoft.SMS.TSEnvironment

$tsenv.value("SMSTSMP") = "LAN-SERVERMP.domain.com:80".

You can also check the gateway and set SMSMPTS based to the correct server accordingly.
