[cifs-protocol] [EXTERNAL] Re: MS-SWM Q9b - CLIENT_MOVE_NOTIFICATION is ignored if the address list includes the ip that was given to Register[Ex]() - TrackingID#2401060040000027

Hi Stefan,

I have the same question for this issue as for SR 2401050040013471. 

Considering that: 
The Windows Client has a 'lazy' efficiency. It tracks the servers it connects to, and updates their Available or Unavailable status internally when it gets the notifications. It doesn't act on the changes unless and until it needs to, such as to find a new Witness node or data connection. By the same token, the Server is also efficiently lazy and doesn't send any notifications that are moot, or the client doesn't need the information. 

Do you have a question on the SWN documentation? What is the problem you're trying to solve?

Hi Stefan,

To collect the t.cab traces from the Client, use 't.cmd clion' and 't.cmd clioff'

Thank you for catching what I missed!

Hi Jeff,

I hope to find the time to collect the required stuff.

> In addition to the traces below, could you also upload any Events from the appropriate time range? > In Event Viewer, navigate to Application and Services Logs > Microsoft > Windows > SMBWitnessSService (from the cluster), and SMBWitnessClient from the client.

But note I was talking about samba being the server and windows server 2022 being the client, so SMBWitnessSService is not relevant. But I'll include SMBClient in addition to SMBWitnessClient from the client.

Is this really correct as I only have windows as a client not a server.

Thanks!
