Rick Varvel, Microsoft Consulting Services comes through with another great paper. I mentioned his papers for the Edge Server in the past and he has now dedicated time to the OC Phone Edition (OCPE, Tanjay) upgrade process.
Due to some of our programs purchasing devices in advance of program needs for budget reasons we ended up with multiple firmware versions. In fact we even had devices with the .199 build for which Rick was testing with.
Here is the text of his blog and url -
Background information on how the different Tanjay firmware builds behave during the sign in and download process to assist with troubleshooting
Environmental dependency settings for DHCP, NTP, certificates, and DNS
Pool configuration changes required to successfully sign in and upgrade a Tanjay
Syntax examples and a sample scenario to simplify the deployment process
A sample NetMon trace file highlighting a successful sign in and upgrade
Log file locations and URLs used in troubleshooting common issues
An Appendix with step by step instructions for many common tasks
