Hi Ried.
Ran services.msc > Modem Lock > general tab
Stop button was grayed out and it wouldn’t hold the Disabled option.
Control Kids exe wasn’t on machine so couldn’t change settings.
Wasn’t in the Add/Remove programs Control panel either.
Lost a little patience then.
Ran HJT, checked Control Kids and Modem Lock entries and “Fixed” them
No change
Ran services.msc > Modem Lock ….. had a look … > Log On tab
In Hardware Profile selected Profile 1 (only one available)
Clicked Disable
Apply
Reboot
Hey Presto !
I was able to download and install the Internet connection software and connect, disconnect and reconnect OK.
I was also able to boot to Safe Mode.
Enabled Modem Lock in the Hardware Profile again,
Rebooted.
Modem Lock came on OK and had no problem with connecting, disconnecting and reconnecting to Internet.
Couldn’t boot to Safe Mode though.
I’d like to get to the bottom of the Safe Mode problem BUT my friend is content that his machine is running much better and his Internet connection is OK again. I guess it’s a successful conclusion.
I hope you don’t feel we’ve wasted your time by drawing this to a close before a complete solution.
Many, many thanks for your help, advice, time and patience
