The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it.

Getting "User not allowed to logon at this computer" when logging in via FTP using a non-admin account.

Asked by mygrosner in Windows Network Security

Tags: allowed, logon, user, computer, log

I cannot login via FTP using non-admin accounts. I get "User not allowed to logon at this computer" in the event logs. I am running IIS 5.0 on Windows 2000 Server. This is a stand-alone server (no AD).

I have checked/done the following:

- verified that the "ftpuser" has "Log on Locally" permissions set
- the IUSR_ accounts also have "Log on Locally" and "Log on as a Batch Job" permissions set
- administrator user CAN login via FTP (so I doubt if it's the IUSR_ permissions???)
- "ftpuser" has "Full Control" permissions on the FTP directory (I did "Full Control" for testing purposes and will
reduce the access to "Read and Execute".)
- all non-admin accounts result in the same login errors listed below.

Error message from the event logs:

Is there something else I need to do? I have locked down four servers with a security template similar to hisecws.inf but only this server has this particular FTP login problem.

This problem seemed to occur around the time the Security Event Log filled up and halted the system (we had CrashOnAudit set). We had since rebooted the server and cleared the Event Logs but still cannot log in. We were able to prior to the system halting. Is there a flag somewhere that needs to be reset?
