Membership.ValidateUser returns error message The server is unwilling to process the request. (Exception from HRESULT: 0x80072035)

I currently have a web site that is integrated with Active Directory using the MemberShip provider.  Everything works fine and I can create/edit/ and change passwords for users. Occasionally a user gets hung and calling the ValidateUser method returns  "The server is unwilling to process the request. (Exception from HRESULT: 0x80072035)" for a particular user.  The only way around this is to delete and add the account again.  Other users can continue to log in to the system.

Here is the method call : Membership.ValidateUser(uid, pwd);

In a brief web search - I found a number of references to this error and the user not having a password that met the Password policy as defined on the domain controller.  So ensure that the GUI enforces the same password policy as AD.

I did.  I even set it to a password that I used to reset mine that did not conflict with the password policy.  Still no luck.  The domain lets me change the password for this user and I can get the user using GetUser(userid).  I still get this error when I try to validate the account.

have you defined a machine key in your web.config?  this will ensure that the password hash is always the same.

can I assume you have both encryption and decryption keys defined?
