The computer you are dialing is not answering please try again later. The most common cause for this is you are not dialing the right number, or your area had 10 digit dialing and you need to include that in the number. If that is not the problem, update your modem driver, put 3 comas behind the phone number, and call your modem manufac and get an ini string. If you are still having problems reinstall your modem, and call your ISP.__________________________________________________________________________________

For example, if you modified the Modem.inf file to add information for an unsupported modem, or if you modified the Switch.inf file to create a script to connect to your Internet service provider (ISP), make sure to back up these files. To resolve this issue, replace the damaged files by removing and reinstalling DUN.__________________________________________________________________________________

(no server assigned) the request is not seen on the network. This error message can occur if you are using both the Banyan VINES 32-bit network client and the Novell NetWare real-mode NetX client. The NetX client is being loaded before the Banyan 32-bit client. This causes Banyan VINES to try to operate over an IPXODI protocol stack, which it is not designed to do. To prevent this issue from occurring, do not use Banyan's 32-bit VINES client with Novell's real-mode NetX client.
