Microsoft assisted me with patching our SharePoint 2013 instance. It turns out the engineer was missing params in the command he had me run, which was this:
psconfig -cmd upgrade -inplace b2b -force -wait
Instead of the full thing:
PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install
We ran into a bunch or problems, some of which were solved by running:
psconfig.exe -cmd secureresources
Next, we had issues opening office documents. I fixed this by running:
Install-SPApplicationContent
Now I am worried we might still have some other issues. Looking at the full psconfig command, I saw there are powershell equivalents for them:
Install-SPFeature -AllExistingFeatures
Install-SPService
Initialize-SPResourceSecurity
Is it safe to run these just to be sure everything was configured correctly? I would run the psconfig wizard all over again but don't want a sustained outage
