I was deleting a DTC using NMMGR and moving some of the device profiles to other DTC's. After completing the changes I did a Validate DTS. When SYSGEN tried to save the config file, I received an error message that the file MISCP.BOOTUP.SYS could not be updated due to a security error. I checked all the files in BOOTUP and they had the same security and all were being accessed by PROGEN.PUB.SYS. I was then asked if I wanted the new config to be activated NOW or HOLD for a startup. I replied NOW and HOLD (tried this several times). The config changed and when I exited NMMGR I received the message that the program terminated in an error state. Did a shutdown and start and now NMMGR works fine with saving the file. Has anyone had this happen? What caused it? Should I be aware of or need to take further action? Everything seems to be working fine.
