Hello Granny RoRo,
Welcome to Microsoft Community.
What did you do before you got Failed to connect to an IPC Port?
Generally, many ports are open by Windows by default, if there is a change in security policy this may have some effect.
This question is out of scope for the Answers Support Community. The best place to get help is IT Pro Community, which is intended to support more advanced users such as yourself.
