忘记host密码?有时候我们会忘记DotNetNuke的host密码,这是一件很头疼的事,这时我们可以通过下面这一段SQL 把host密码重置为一个已知用户的密码(假设这个已知用户名为m2land)。

原理其实很简单,这段 会把aspnet_membership表中的"m2land"用户的password和password_salt值拷贝并覆盖host对应的值。
使用方法请参考 中的说明。

附:还有一个版本的 ,这个版本是直接调用Asp.net的存储过程来修改密码,在我看来更方便,但不知为什么不起作用,望赐教!

SQL recovering host password use asp.net store procedure

另一个方法:

As there arefrequent requests from users, who lost the password of the host account(and you cannot request the host password by email), the followingsolution will help for all DNN 3 and 4 installation. Please note, thatyour need direct access to the data to suceed with the issue:

  • if "register" is not displayed for the portal, go to table "Portals"  in your data and enter value "2" into column "Registration".
  • create a new user account by registration (this time, please remember the password you enter!)
  • go to data , enter table "ASPNet_Membership"
  • go to new user account (usually the last one) and copy the encrypted values of columns "Password" and "PasswordSalt" into the same columns of user account "host" (usually th first entry in this table) 
  • login as user "host" using the new password and delete the reshly created other user.
  • Keep remembering your password ;)
