OS deployment using the same staging dock for multiple clients is a bit of an issue, and there are many different solutions to the problem but all have their downsides.
I did a quick search and found two probable candidates to tackle.
- UUID staging
The idea is to exclude staging docks using a registry value (new in 1610) and stage using only UUID. This way the MAC address is totally irrelevant and OSD is handled using only UUID. The downside is that many Prestage tools use MAC and the UUID Guid is longer and therefore more prone to mistakes.
- Ethernet MAC release/Wifi renew
This method prompts the user at the end of the task sequence to disconnect the ethernet adapter and then resumes using Wifi. The downsides here is that the task sequence no longer becomes unattended and therefore can take longer time. This also requires the use of extra filtering in task sequences and therefore extra maintenance.
With that said I came to the following solution.
On the Site create a SQL job that runs every 30/60 minutes and removes the MAC association and clears the PXE flag.
This allows users to stage their clients using the same Ethernet adapter (USB or docking station) without changing the current pxe routine/application or task sequence.
As with all staging dock solution some consideration must be taken of when the job is scheduled to run so that MAC address association is not wiped before PXE is initated.
If staging is done once a day/week the schedule can be configured to a daily job and thus the afforementioned consideration becomes a non-issue.
