Hi Forum, I have system crash and I am not able to log-in to Windows XP. Here are the details below . . . Problem: I have DELL laptop with XP professional that I've been using in my company in Mexico.Now, I am on business trip to India. I wanted to access the internet using my laptop. So, I had been to a public internet surfing place (so called "Cyber Cafe"). The guy there changed my laptop settings and now I am unable to log-in to windows using my known company username and password. What is changed? The guy at cyber-cafe changed all the IP addresses settings. Then he changed the domain from my company to workgroup as "funzone" (which is workgroup name at his place) then windows asked to reboot for changes to take place. Now, I can't log-in using my known username and password. The windows log-in screen only shows username and password fields and the domain/workgroup selection field is missing. After log-in windows says that "can't log-in, please check usename and domain name" What I've tried? I have tried pressing F8 before windows booting and selecting ALL different boot options for windows (e.g. safe mode, last known configuration, etc.) But, same problem in each case. I tried to login using different combinations of username and password e.g. my known usename and empty password, empty username and password, Administrator and my known password, guest (this gave me message that "guest" account is disabled) The solution: Please let me know what has happened and what could be probable solutions. Note: This is very urgent request as I have all the data in laptop and I have to give presentations in coming week. I need to work with my laptop immediately. Thanks a lot for reading my thread/post and any help is highly appreciated. Regards, Ravi
