How to spilt information within a cell

I have a ton of information automatically being generated via a report to Excel.

The mass of information is being dumped into cell H on my excel spreadsheet as shown below.

A user account was locked out. Subject: Security ID: S-1-5-18 Account Name: NJAUDBFD01$ Account Domain: ENTERPRISE Logon ID: 0x3e7 Account That Was Locked Out: Security ID: S-1-5-21-1876172974-742851678-1849977318-139445 Account Name: CMKRF Additional Information: Caller Computer Name: 1067899A

I want to separate both Account Name: fields and the Computer Name: field into their own cells, and then I want to generate a script that will provide the count of how many times the "Account Name:" was locked out and which "Computer Name" they were locked out of.

If you need additional information please reply and I will provide it.

I thank you for helping me out.
