    Hello, I just recently with the last couple months started having this issue now with multiple systems running windows server 2012 Standard R2. It seems whenever either the PC reboots or print spooler restarts any installed printers will still show installed but the port they were using will disappear from the computer. It doesn't matter if I try to view it from printer properties or the print server manager neither will show the port but if I try to recreate the port it says it already exists. So far the only solution I've been able to find is create a new local port after altering the share name of the printer.

    It doesn't matter if I have the printer using a standard TCP/IP port, a local port using the UNC path for the printer, or just a quick add using the add printer wizard all of these will lose the port they install on. 

    I've tried looking for the ports in the registry under HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Print \ Monitors \ Standard TCP/IP Port \ Ports   
    I know this is most likely the work of a windows update gone bad just having trouble  determing the update and what a permanent fix may be so I'm not constantly troubleshooting printers.

    HI
    1.what's the issue printer model installed on issue server ?

    2.when the problem happened ,are there any event log in below location on w2012r2?
    event viewer\windows logs\
    application
    system
    event viewer\windows logs\applications and services logs\microsoft\windows\printservice

    3.when the problem happen ,can you print the document to missing port well ?

    4.if you creat a local new user account then log on this server,will the same issue happen on this new user account ?

    5.did you check which difference about the permission the below registery key and sub key,before restarting spooler service and after restarting spooler service ?
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\
    local port
    standard TCP/IP port

    6.is there normal server in your environment ,we can also compare the permission between issue server and normal server.
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\
    local port
    standard TCP/IP port

    7.we can enter below powershell command on both normal server(w2012r2) and issue server(w2012r2),then check if there are difference between them.
    $QFE = Get-hotfix -computername $server | select-object -property Description,HotFixID,InstalledBy,InstalledOn | out-file c:\windows\temp\$server.txt
    change $server to hostname
