Nazgul Tl Posts: 3	Posted - 9/10/2001 1:02:39 PM After i installed WinXP Pro, it is very difficult to connect to the internet with my modem (US Robotics win int PCI v90). I am often (when my username and password are being checked) becoming an error message. It says something about loopback detected (error 737). I use the drivers that are shiping with WinXP. With other versions of Windows i hadn't this problem. What's wrong!? Please help!!!

Nazgul Tl Posts: 3	Posted - 9/11/2001 4:56:42 PM I tried everything but it didn't help! The following is the copy of the log file of my modem, when it attempts to connect, perhaps someone can tell me what exactly happens at the connection and can maybe resolve the problem: 09-12-2001 01:40:16.112 -

Bob Starnes Tl Posts: 4360 USA	Posted - 9/11/2001 11:06:50 PM The Error 737 appears to indicated a Windows XP problem, not a modem problem, might check in a XP newsgroup. Think Microsoft has a discussion forum at the Windows XP homepage, may get a clue there.
Nazgul Tl Posts: 3	Posted - 9/12/2001 9:23:07 AM OK, i will try it there. Thanks anyway. But if someone has a clue, please let me know.
