While you could remove the MS Client in the control panel, most will not be happy that all passwords to things like email and more will not be remembered.
The usual fix is to ..
1. Delete the .PWL files in C:\Windows
2. In the network control panel, set the logon to Windows.
3. Ok your way out, reboot.
4. For the last time, enter a name and click OK. Do not touch the password or cancel box or you go to step 1.
PC is Athlon 1800+ with Windows ME 560mB memory IE6.
I have recently upgraded from dial up cable to cable broadband. Since the upgrade I get a request for a password during start up. This only happens when the modem is on during start. Can this be avoided. The PC is on its own and not intentionaly networked. Also some memorised password and logon info does not work , with a remark message saying this is not memorised for networked PC's
