RMAN Backup to UNC Path [message #677678]

Going out on a limb here to see if anyone might have an explanation for the issue I am seeing.

From a test environment I can put in a UNC path for the RMAN backup location and it works just fine. From another environment I get the following error:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup plus archivelog command at 10/02/2019 14:09:29
ORA-19504: failed to create file "\\SERVER02\IFSBACKUP\RMAN\PROD_20191002_23_1.BAK"
ORA-27040: file create error, unable to create file
OSD-04002: unable to open file
O/S-Error: (OS 1326) Logon failure: unknown user name or bad password.
Recovery Manager complete.

I didn't know if there is some other parameter or setting that is allowing one database to use the UNC path and another not to use it. I can navigate to the path from the server and create new files, so....

The instance or listener owner must have the privileges to access the network and to access this UNC path.
Check which account is launching these services.

Thanks, I have discovered that the service is running as a local server user account rather than the Local System Account. I will have to check into what is needed and required to switch this back to the Local System account.

Local system is probably no good: it wouldn't usually have any privileges on a remote machine. Domain users are probably the best way to work as (if I am correct - I am not very good with Windows security) they are the same on all machines and can be granted privileges appropriately.

The database that does properly backup to the UNC location is using the Local System account, so changing to that on the other database should work just fine. I just need to know if changing those services has any hidden side effects or not. I have been used to running Oracle on Linux instead of Windows.
