SMBServer: License usage for a product licensed in per server mode is nearing the maximum number of licenses purchased event log?

If you're facing this popup message box or found out that your event log filled with the warning above, you might be interested to look further on Microsoft official website.

I was facing the same problem but that particular solution didn't help me to resolve the issue. My further researched/googled, I found out another solution toward the similar problem. I am not sure if it will solve the issue but hope to try it out tomorrow.
