One of my friends in my building as a 256 Kbps unlimited Triband connection. His Modem is the MTNL branded 4 LAN Port xDSL Modem. I checked his Modem config which is configured in Bridged mode & thus he dials through Win XP using the WAN Miniport connection - which works fine. His colleague now tried connecting his Laptop on another LAN Port & tried dialing out using WAN Miniport connection on the Laptop. Unfortunately it always pops-up an error "Error 921: Incorrect username, password....", though the credentials entered are correct. As per his friend, his company might have prohibited ADSL dialing through an Active Directory Policy.Now comes the main issue, if I try configuring the PPPoE authentication on the Modem on PVC0 it still doesnt work & the Modem log again shows "Incorrect Username....". Could anybody help me out of this?Thanks in advance
