Last night's update knocked out TCP

No network connections. Can't run system restore to get rid of the update.
Help please, Microsoft

More information would be helpful.

Let's start with which OS you have?

Then, if you look at Device Manager, does the NIC have a yellow question
mark against it?

Open a Command Prompt and type IPCONFIG /ALL then post the result.

Post the entries in the C:\Windows\WindowsUpdate.log file from the last
update.

XP SP2. Good. That's a start.

OK. So you can't access the Device Manager for some reason. Fine with that.
What if you go to Control Panel | Network Connections? What does it show? Are
you on a LAN or using dial-up/VPN?

Still... Would like to see the output from IPCONFIG /ALL, and the most
recent info from the Windows Update log.

Of course, I doubt this is an AU problem unless it downloaded a naff driver,
but then your AVG update wouldn't of worked.

All most odd, agreed. I used the net just fine before applying the update -
didn't download anything, didn't install anything. Anyway, the Repair install
has completed, and all seems fine again, happily .... phew.

Further investigations. First reboot after the above returned PC to no
network condition. Server (lanmanserver) service stuck on "starting".
Dependent on Computer Browser service, which had failed to start. Judicious
googling suggesting uninstalling File & Printer sharing, and this has done
the trick. Hopefully it will re-install OK without further wasting of time!
