Honestly, from what you have written, it is hard to determine what is going on. You should call the Clerk of Court to interpret the Notice. What it appears to me to be is: Notice of Contemplated Dismissal for Lack of Jurisdiction". The "Order for Alternative Service" fills in the missing piece of your puzzle.
It appears that you filed your case Pro Se, and that you have failed to effect service upon your spouse (Google "Service of Process"). So, the Court is warning you that unless you request a reissue of Summons, and re-attempt service upon your spouse, the Court will dismiss your case because there is no case until the soon to be ex-spouse is served.
Now if you have tried to effect service several times and failed, then a Motion for Alternative Service must be filed with the Court. Otherwise, again, the Court will dismiss your case because there is no case until the soon to be ex-spouse is served via alternative methods.

It means that the Court will dismiss your case if you don't properly serve the Defendant with the Writ of Summons and Complaint. If you are having trouble serving him or her, then you will need to file a Motion for Alternative Service stating the attempts you have made to serve the Defendant and why he or she has not been served. Then the court will issue an Order for Alternative Service where they usually post the information on the sheriff's door and it is considered "good" service.
