I'm trying to reinstall antivirus software on a domain controller becasue it won't update itself. When I run the installation exe, I get an error saying the application failed to start becasue msvcp71.dll is missing. I have heard that if you reinstall this .dll. some things break, like MSN.
I have two questions: (1) Of course MSN is not a concern on a DC but I want to make sure I don't break something else. Does anyone know if there is a risk of breaking any functions or services on the domain controller if I copy the missing msvcp71.dll file from a different DC to the one that is missing the file?
(2) Is it adequate to just copy the file to the right path or do I need to also register it with the regsrv32 command? Or is there a download available from MS that will install it and register it automatically?
