I have a SharePoint farm with two WFE servers, two backend servers and two SQL servers. I last installed CU's last year (July 2017).
I have gone to the servers in the farm this week to see that upgrades are required, but that the two WFE servers are blocked because the two backend servers are claiming that they require SP1 to be installed:
Update for Microsoft SharePoint Enterprise Server 2013 (KB3213569) 64-Bit Edition 15.0.4945.1000 Missing/Required
Service Pack 1 for Microsoft SharePoint Server 2013 (KB2880552) 64-Bit Edition 15.0.4571.1502 Missing/Required
The thing is, I already installed SP1 in 2014 (I mean, I must have installed it, because you can't install any subsequent CU's with out it!)
My questions are:
- Why is it asking for something that's already been installed?
- Can I just reinstall SP1? What will happen if I reinstall it?
- If I can't, what are my options?
