Cannot communicate with Windows Update server no matter what I try

I think your problem is cause by Cisco AnyConnect Client software.

VPN - Uninstall Cisco AnyConnect Client on Windows | Office of Information Technology

I didn't have that exact program, but I have removed the Cisco VPN client and the result is the same.

I'll try from home so that I can make sure it's not the "SCCM" stuff interfering.

With this batch script you can reset TCP/IP protocol suite to its default settings.

Code:

@Echo Off & Cls

net sess>nul 2>&1||(powershell start cmd -ArgumentList """/c %~0""" -verb Runas & exit)

Call :IsAdmin

netsh winsock reset  2> nul

netsh int ipv4 reset  2> nul

netsh int ipv6 reset  2> nul

netsh int httpstunnel reset  2> nul

netsh int portproxy reset  2> nul

netsh int tcp reset  2> nul

At home I was able to connect to Windows Update and install updates. So it must be the SCCM settings they have at work.
