Need help installing SharePoint 2013SharePoint

Not sure if this is the right place!  I installed SharePoint 2016 on a 2016 Server for a client.  Then they got crypto on their mail server so I installed Exchange 2016 on the server as well.  I rebuilt the old mail server and migrated the mailboxes.  Started working on SharePoint and realized it wouldn't work with SQL 2008 R2,so I uninstalled SP2016 and installed SP2013 - couldn't get it to search, conflict with the timer service installed by SP2016 or something in Exchange 2016 so I uninstalled both.  Have tried to reinstall SP2013 but can't get into Central Admin or any other sites in iis.  Am about to scrub the server and start over.  Does anyone know how to completely manually remove all SharePoint stuff so I can start over with a fresh install.  Any other advice would be great

  1. Exchange server, SharePoint server, and MS SQL server are definitively products that you shouldn't be going "installing" and "uninstalling" at will.
  2. Active directory is the base of (Exchange, SharePoint and also, Skype for business), for this reason, if you install one you can't uninstall it and think that is all gone, it has never worked like that and never will be. They left signatures all over the AD, furthermore, the schema of the AD is extended for these products and ADSI clean up is required.
My recommendations.
  1. You need 1 server for each product (1 for Active Directory, 1 for Exchange Server, 1 for MS SQL Server and 1 for Sharepoint Server)
  2. If you have exchange server working, leave it alone and install Sharepoint on a new formatted server, following the best practices of SharePoint you shouldn't install SPS on the same server where you have the SQL Server, they should be separated.
  3. Start from scratch whenever is possible in new computers or virtual machines if your hardware has the resources.

Do you really want to go production on a box that's already been a PITA?  Not I!   I concur with Jose - you want 3 separate boxes for SQL, Exchange and SharePoint, there's enough going on in IIS with AD, SharePoint and Exchange that I get a headache trying to think about merging the two.  (Recall SBS server?!!)  

Of course your domain controllers ought to be separated, I wouldn't want to expose my DC's and SQL to the internet like Exchange will be.

Advice above is very good and accurate. To answer you question:

"Does anyone know how to completely manually remove all SharePoint stuff so I can start over with a fresh install."

Format C:

In other words, nuke the box and start with a totally fresh install including the Operating system. The additional 2 or so hours of work will save you lots of trouble and hours down the road.

Good luck....
