Background
The main issue with this error is that the logon service is timing out in waiting for a response from the server. So after having the tech do some initial troubleshooting, I decided to see if there is a way to tweak the timeout value. The answer is "yes"!
TL;DR
Key: HKLM\SYSTEM\CurrentControlSet\Services\NetLogon\Parameters
Type: REG_DWORD
Name: ExpectedDialupDelay
Value: 0-600 (in seconds)
