During one of the test runs of SDNExpress, I discovered the VMs failed to join the domain -- with no error reported by the script. Instead, the VMs remained in "WORKGROUP" mode and the SDNExpress script went into an infinite loop trying to contact the VMs (since they never joined the domain, there were no corresponding DNS records and thus the VMs could not be found).
The problem was the network configuration did not specify a default DNS suffix for the connection.
To avoid this issue, the DNSSuffixSearchOrder should be specified in the custom unattend file generated by SDNExpress.ps1.

When the DomainJoinPassword or LocalAdminPassword contains invalid XML characters (e.g. '<' or '>'), the following error occurs when deploying Network Controller, SLB (MUX), and Gateway VMs:
Windows Setup encountered an internal error while loading or searching for an unattend answer file.
This is due to the generated unattend answer files containing invalid XML.
For example, imagine the configuration file used with SDNExpress.ps1 specifies the following:
DomainJoinPassword = 'PN5<wxNw&j9'
This results in the following element in the unattend answer file:
<Identification>
<Credentials>
<Domain>...</Domain>
<Password>PN5<wxNw&j9</Password>
<Username>...</Username>
</Credentials>
<JoinDomain>...</JoinDomain>
</Identification>
To avoid this error, invalid XML characters in the passwords need to be escaped when generating the unattend answer files.
