PXE / WDS Across trusted Domains not working

[gvlaarho]

Hello all, i have a problem with pxe:

Description :

Domain 1 : Dom.Domain1.com

Domain 2 : Dom.Domain2.com

PXE and SCCM : SCCM.Domain1.com

PXE Server configured by DHCP Scope options 66 and 67

When I connect a computer from Dom.Domain1.com, no problem

When I connect the same computer from Dom.Domain2.com,

1. computer receive one IP from DHCP of Dom.Domain2.com
2. computer connect well to the WDS of Dom.Domain1.com
3. computer start the smsboot\x64\pxeboot.n12
4. When I look into the smspxe.log, I see that the image PRI00002 should be downloaded
5. Computer show: downloading \smsboot\boot.sdi for about 30 second
6. Computer stop the process with 0Xc0000001 A required Device isn’t connect or can’t be accessed

I don’t understand what happens

My question: is it possible on domain Dom.Domain2.com to use the wds of Dom.Domain1.com

 

Thanks to all

I have found the problem:

I had to modify the HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\DP\RamDiskTFTPBlockSize to 8192 instead of 16384 (changed a few times ago)

After that, everything went ok except that it is extremely slow.

I had to analyses the network possible issue, then after made a traceert, i have seen that there are too many drops and latency.

 

Conclusion: New DP localized in the second domain with pxe

 

Everything is ok now
