Logon failure: user account restriction. Possible reasons are blank passwords not allowed, logon hour restrictions, or a policy

Question

I'm trying to create a website on an Intranet, but when i try to log in the main page this message appears:

"Logon failure: user account restriction. Possible reasons are blank passwords not allowed, logon hour restrictions, or a policy restriction has been enforced."

I'm sure that this error has to do with my IIS settings, but I can't figure out where exactly. so can anyone help please?

I have winXP sp2, and my site is built using VS2005 C# code behind.

Thanks

I have been struggling with this one for a while now and this quick tip worked! Awesome, thanks!

Answer 11

Please note that this also fixes issues with network connectivity between two Windows Server 2008 boxes on a workgroup in addition to this error when adding a linked server between two SQL Server 2008 instances:

"Login failed. The login is from an untrusted domain and cannot be used with Windows authentication."

 

Thanks so much for the tip - this has literally saved me hours of work!

Answer 12

I agree with the other posts....you rock man!

Answer 13

Thanks a lot, this helped me solving my networking problem.

Answer 14

That works, thanks.  But I experimented and found that another solution is to simply create a password for the administrator account. 

The anti-virus people say that it's advisible to have a password on your administrator account.  I would imagine that getting rid of the LimitBlankPasswordUse flag would make that vulnerability even worse.

So I went with creating a password.  But thanks for the information.

Answer 15

The best Way is go to network sharing centre and left panel click on change network sharing setting>then go to turn on pasword sharing row, change it to turn Off. it will work.. Thankss

Answer 16

Thank you

Also I found another solution:

goto start->run->control userpasswords2

you can see IUSR_MYSTATION user which is Guest user that could be an IIS user

Reset password to anything except blank... DONE.
