here's two thoughts:

In regedit, right-click on key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters" and go to the Security tab. Give NT AUTHORITY\NetworkService permission to Read that key.


set the ms exchange transport service to run as local system
start > run > services.msc, double click it, log on as, local system

thank you very much for your quick response. I tried both the solution, but unfortunately it is not working for me. Transport service still showing same issue and generating same error event ids in  application events
Can you ensure Exchange is totally up to date with service packs and updates along with OS, and if all are totally up to date, restart server and retry.
