I am working on windows server 2012 R2. now I have the following case:-
- Inside IIS I have a .dll file named project.dll .created on 1/1/2016 , last modified on 1/7/2016.
- I took a copy of this file. save it inside a secure place
- now I wanted to test a new version of this .dll file. so I copy/paste an updated version of the project.dll file from our test server to our pre-live server. where I specify to replace the current .dll.
- so now the updated .dll have the following info. created on 1/1/2016 & last modified on 1/11/2016.
- now after the test . I realize that there are some errors, so I want to return the old .dll
- so I copy the .dll from the secure place, and paste it inside IIS related folder. and I chose to replace the current file.
now my question is how I can know when the operation on point number 6 occurred? as the .dll will have the original info; created on 1/1/2016 & modified on 1/7/2016. but I need to know when exactly operation 6 happen. in other words when the updated .dll was replaced by the original .dll ? as I need to check some logs to see if the errors were removed at the time the updated .dll file was no longer in place..
