Unable to update the password

 

This can be super annoying.  You need to change your password but when you enter a completely legitimate, compliant new password you just get:

Unable to update the password.  The value provided for the new password does not meet the length, complexity, or history requirements of the domain.

WHY!?  It's NONE of those.

There may be a policy in force that limits the number of times you can change your password within a specific time period.  If it set to 12 hours and your password was changed less than 12 hours ago you will get the above response.

PXE-T04 and PXE-E36 errors

 

This was encountered in a lab environment.  Everything looked fine.  Network ports all checked.  Another existing windows client on the same subnet could even complete the TFTP download of the target smsboot\x64\wdsnbp.com file.  Event logs indicated that the TFTP transfer began but then failed producing a an Event ID 4101 in the Deployment-Services-Diagnostics Admin log.

The Following Client failed TFTP Download:
Client IP: 10.0.3.13
Filename: smsboot\x64\wdsnbp.com
ErrorCode: 1460
File Size: 30832
Client Port: 2071
Server Port: 53574
Variable Window: false

This post suggested a block size change which resolved the issue after a WDS service restart.

This older article also refers to block size changing
https://support.microsoft.com/en-gb/help/975710/operating-system-deployment-over-a-network-by-using-wds-fails-in-windo

Changing the block size is achieved in the registry as follows

Location:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WDSServer\Providers\WDSTFTP
Name: MaximumBlockSize
Type: (REG_DWORD)
Value range: 512–1456
Base: (Decimal)

Setting a 512 value resolved the problem.

The value can also be changed in the WDS applet in Maximum Block Size on the TFTP tab of the WDS server properties.
