Redeployment Managed Computer menu not consistent
I upgraded to 7.5 yesterday. After fumbling around for awhile, I was able to find the settings to get the redeployment menu to show for already managed computers, but it's not consistent.
I couldn't get the menu to show on the first machine I tried (it had been powered off since before upgrade, agents not updated on client). I thought maybe the deployment agent needed to update so I powered it on to update and tried a 2nd machine.
The 2nd machine was showing the menu properly consistently (agents were updated on this machine). Then I decided I wanted to change the text of the prompt, did that in NBS General Settings with "Apply NBS settings immediately" checked. Confirmed on server when I made the change that config was requested and changed.
Rebooted 2nd machine and it didn't prompt, went right to "Symantec NBS pre-select automation processing" and booted to production. Rebooted and same thing. Restarted Symantec Network boot service on server and no change.
Rebooted up 1st machine that had not worked previously, and it correctly sees the redeployment managed computer menu and the new prompt text now.
Rebooted 2nd machine a few times, and it continued to not show boot menu, then it just started working again (and so far consistently).
When making a change to NBS General Settings, is there some cache on the server that needs to clear itself out, or some time period that needs to pass for agents to work as expected? Or how can I troubleshoot if this issue continues to happen, where some managed machines aren't getting the menu ?
Also, can someone confirm if the DS agent on the client needs to be updated to see the menu?
Thanks, as always
