I accepted an offer from Norton System Works to correct a boot sector error. This resulted in an "NTLDR is missing" error message which I had to resolve by formatting the hard drive and re-installing Win XP Pro.
It occurred to me yesterday that if I restored the system state from a full backup made in September it would probably save a lot of time re-installing programs (big mistake!). The desktop carried on happily until I closed it down last night.
This morning I had the "IP Address Conflict" error. This continues to come up even when I try to boot from the XP Pro CD with SP2 on it. The boot-up will not continue after this message.
Between the last full backup and a few days ago I set up a network connection between the desktop (which is showing the "IP Address Conflict") and the Toshiba notebook from which I am sending this question. The IP address on the desktop had to be changed in order to make the connection work.
How do I get back into the desktop so that I can change the IP address to avoid the conflict?
