2012 Server and permissions NT AUTHORITY\SYSTEM

Hello EE,

Our company has a custom exe , ran fine under 2003 server 32 bit , when installing on windows 2012 64 bit , I receive error . Upon inspection with process monitor , I see FILE LOCKED WITH ONLY READERS, on operation CreateFileMapping C:\Windows\System32\sechost.dll and on C:\Windows\System32\mscoree.dll , this is as user NT AUTHORITY\SYSTEM . So it appears the process cannot access the system 32 folder . How would I go about correcting this ?

It runs as a service .
What service user does it run as, e.g. - (LocalSystem, NetworkService)?

10 Tips to Protect Your Business from Ransomware

Did you know that ransomware is the most widespread, destructive malware in the world today? It accounts for 39% of all security breaches, with ransomware gangsters projected to make $11.5B in profits from online extortion by 2019.

Local System Account
Local system does have access to the System32 directory.
One advantage of running under the LocalSystem account is that the service has complete unrestricted access to local resources. This is also the disadvantage of LocalSystem because a LocalSystem service can do things that would bring down the entire system. In particular, a service running as LocalSystem on a domain controller (DC) has unrestricted access to Active Directory Domain Services. This means that bugs in the service, or security attacks on the service, can damage the system or, if the service is on a DC, damage the entire enterprise network.

This leads me to believe that there has to be some other issue.

What is the exact error message you receive when you start the service.  Also look in the event log to see if there is any additional information.
