I have a Toshiba Equium 7100S with Windows XP Pro (Service Pack 1). I am having trouble getting my dial-up ISP software to connect. I have contacted my ISP provider's help desk with zero resolution. I have tried 3 different 56k modems (two internal and one USB) all resulting in the same problem. The system attempts to connect and initiates the "handshake" but ends up disconnecting. An error number is given, but no description is provided. Not very helpful. I have tried all of the available access numbers for my area. The user name and password are correct as they are in use on another computer (that I'm hoping to replace with the one I'm working on). I am able to use the modem to dial my cell phone through HyperTerminal, so I know the modem is working properly. I have attempted a couple other ISP software packages besides the one I have an account with and they all have the same result - attempt to connect for a short period and then close. There aren't any device conflicts as far as I can tell. I have disabled the XP Firewall and there isn't any anti-virus installed (that will be changed just as soon as I can complete the setup of the dial-up account). I think that pretty much covers all that I've done. I hope someone can point me in the right direction. Thanks in advance for any and all help.
