If you are not able to connect to the Mosaic home page, check your winsock and network configuration to verify the IP (Internet Protocol) numbers. After verifying that you haven't entered an IP number incorrectly, call your network service provider and verify that the IP numbers you were given are correct and that your account is active.
NOTE: You should not have more than one winsock.dll available to Windows at any time because this creates system conflicts. Do not mix and match proprietary winsock or network software (e.g., you are using Novell network software and also trying to install the Trumpet winsock). This does not work.
If you are using proprietary software (e.g., Novell), you should use their associated winsock.dll. Using another winsock can cause configuration problems.
