Hi Porter -
I'm Kevin B., I do apologize for the inconvenience that you're experiencing right now, let me help you sort things out.
Does the company internet have its own policy? When you connected to a different network, is the network connected with the same company internet or just a personal network?
If the update downloads and install using a different network other than the company, then it might be a restriction applied on the company network which blocks the download and installation of updates on your windows computer.
To ensure that the issue is not with the windows updates on your computer, you can run the Update troubleshooter to identify the issue.
Windows Update Troubleshooter

Check if the tool detects the issue with the updates and check if its able to fix it.
Hope this will help and have a bless day!
Thanks.
Kevin B.
