Vista Workgroup reset bug caused by Sleep/Suspend mode?

I ran into an issue today whereby it appears that upon resuming my Vista Home
Premium machine from Sleep mode, that my workgroup setting had been reset
back to the default value of 'WORKGROUP'. As a result, I was unable to access
resources on my network that I was able to reach perfectly fine last night
prior to putting my machine to sleep. Re-entering my workgroup name and
rebooting fixed the problem.

Has anyone else encountered this issue or have recommendations as to the
easiest way to bring this to the attention of Microsoft engineers?
