Hi Ramesh,
i faced similar problem. but none of the above solution solve my problem.
1) using the editior from (
http://home.eunet.no/~pnordahl/ntpasswd/) I
checked that the "C:\Windows\system32\userinit.exe," is in place
2)This is not about compromise by virus.
3)Happen after i sent my registry key for my Remote Users to update the
logon banner
See, the problem is this. we need to update the logon banner. HQ was
successfully logon with AD. We decided to update the Remotes office by
editing the registry key.
I made changes to mine registry key with the Banner Information at the
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon key
on the 2 data named: "LegalNoticeCaption" & LegalNoticeText"
I have cleared the following (only these) value in the following data to
remove any site specific information before exporting
DefaultUserName=""
AltDefaultUserName=""
AltDefaultDomainName=""
DefaultDomainName=""
I kept the rest default as per MY machine and the final regkey is at the
bottom.
I then tested the registry key with 2 users in Johore (Malaysia) and Medan
(Indonesia), it turn out fine.
I massed mailed to my Remote Offices and now I have 2 users from
Japan(Osaka) and Korea (Seoul) having this sympton. It goes into
Login/logout loop. A check with Seoul shows that the Userinit data is
correct (using the same editor mentioned above.)
Prior to this, these users have never logon to their machine before, it's
autologon for them as they do not need to logon to any domain, it's all
local. Investigation show that my regkey has turn off the autologon for
them. It was initially thought to be credentials problem since they do not
know any password. But by using Administrator and keeping the password blank
allow them to logon. and hence the next problem, the login/logout loop. They
are both on win2k professional.
Question
1) What else can i check to get out of the loop?
2) Could the other registry data value has cause it? Should I have removed
the rest?? I thot it shouldn't affect.
