Sharing your Copilot notebooks - Is being rolled out

on
Microsoft is rolling a new update to Copilot Notebooks that make collaboration even easier: the ability to share Copilot Notebooks with your colleagues.  Personally, I like Notebooks because they feel almost like small, personal agents I don’t have to configure. They give me a safe space to collect notes and documents and then work on them over time. With this update, that personal space can become a shared space for a selected group of  colleagues, without compromising security or permissions. I think it is also important to note that your chat and chat history within the Notebook stays private. The web rollout began in late October and will finish by December, while mobile access starts in early November and are related to the Microsoft 365 Roadmap ( ID 506851 )  You can also read more about the Copilot Notebooks experience on the Microsoft website here . If you like this update and want to stay informed about similar improvements, feel free to follow me on LinkedIn!

A thing about DHCPUtil -EmulateClient

on
I was trying to troubleshoot a Lync phone registry issue for a client of mine, and I ran into an issue I haven't seen before.

As I do not have access to every LAN to every customer at all times, I often get the customer to run certain commands and have them read me the output. When troubleshooting the registration of a CS-Commonareadevice, one of these commands are "DHCPUtil -Emulateclient". I send them instructions on how to map to the Lync server, set their path correct, and run the command from dos.

Usually, I've only been concerned whether the result is a failure, or success. Preferably have the client read out loud the bottom lines of the output. It would look something like this, and I'll say: Read me the result, and what ever information below "result".:


If the result is "success", and everything else seems valid, I will then move on to run the test-csphonebootstrap command, and try to understand the underlying issue.

This is what the test-csphonebootstrap had to tell me:


If you look closely at the TargetURI, it is missing something. It should contain the FQDN of the webservice providing the RootCertChain. So I told the customer his DHCP was all wrong, and asked him to fix it. He's reply was: "No, it's not". And he provided a screenshot of the settings/options showing everything was in order (Or at least it looked like it was in order)

Time to inspect that DHCP ACK packet in-depth. Or at least scroll up a line or two. And try to figure out what was happening.

This is what I saw with my own eyes:
Success, and the correct provisioning url as shown in the first screen shot. But as I scrolled up, I saw something interesting:


Taking a closer look at the option 43 as the client read it, it revealed the values were read in the wrong order.
I do not know why the result came out "Success" or why the output seemingly gave the correct provisioning URL. But I do know the phones didn't register and the test cmdlet gave me an error, and cleaning up the DHCP (removing settings, and reapplying them as described in this post) fixed the error.

Lessons learned:
- Don't always accept "Success" as a definite answer when troubleshooting. Sometimes you still need to take a closer look at things. The -Emulateclient obviously only look for the values in DHCP, and it doesn't do a syntax check. Nice knowing? It took me a couple of rounds before I really realized what was wrong.
- And from now on, I will have to ask the customer for the entire output not just the result.
