I have tried the repair programs that are suggested here with no luck. Have tried closing Zone Alarm and deleting the suggested files from the Temp Internet Folder also. Have checked cookies also. Can ping yahoo, etc. Can't reinstall IE as don't have the disk anymore.
Also after Win 2000 server boots get a message on desktop: SCHWIZEX.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created.
Any suggestions welcome.
