KB6442: ‘Error in login. You cannot login as Windows user’ error occurs when trying to login to MicroStrategy Web 9.x

Error in login
You cannot login as Windows User. Please ask the Strategy Server Administrator to link this Windows User account to a Strategy Server User or ask them to set the Web server properly.

 

CAUSE

One of the possible causes for this error is that the user's client machine was subject to an operating system software change/upgrade and the Microsoft Windows user account for that machine was reset. Because of this reset, the link between the Strategy user account and the Microsoft Windows user account is no longer present and therefore the user cannot be authenticated and granted access to Strategy Web 9.x.
 
ACTION
In order to resolve this issue, the Strategy Administrator needs to re-map (link) the Strategy user account to the newly reset Microsoft Windows user account in Strategy Desktop 9.x.
