Hi!
I have permanent error on my Sharepoint 2013 with DPMRA. About twice time a week it's fault to start, because his port is stolen by mssearch.exe.
I changed DPMRA port from 5719 to 11000, but it's not help. mssearch.exe sometime use this port too.
Try to use port reservation, like listing bottom, but it does not help too.
REG_MULTI_SZ ReservedPorts 11000-11000
(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ReservedPorts)
(https://support.microsoft.com/ru-ru/help/812873/how-to-reserve-a-range-of-ephemeral-ports-on-a-computer-that-is-runnin)
What have i to done to isolate DPMRA port from mssearch.exe? May be there is some pools of ports, that already reserved?
