Hi folks

Office network:

Central PC running Windows 2000 Pro, connected to Demon via BT Highway
128K ISDN.
Laptop running Win98SE.
One desktop running WinMe (I know, I know)
Two desktops running XP-Home.
All networked together, obviously. Wired ethernet.

Central PC's Demon connection is shared.

Now, this has all worked fine for a couple of years. But yesterday, I
had to install a VPN client (on to the central PC) to support one of
my customers, and after rebooting, none of the other PCs could access
the internet. Browsing & file-sharing between them all still works
fine, but my internet connection now appears to be limited to the
central PC only.

I've since uninstalled the VPN client, rebooted. Removed the Demon
share, rebooted, reinstated, rebooted. Rebooted all other PCs. NOTHING
makes any difference - the connection just don't work anywhere other
than the PC that's got the ISDN card!

What did I miss here? Or should I just give up and reinstall the
operating system?

All and any help much appreciated.

Ken.
