Changed DC/Admin PW: HAP login now does not work

I have changed the DC/Admin password on the server, now when a user tries to connect to HAP once they login with their details Server Error in '/HAP' Application
error page is displayed with the unauthorised page - Line 38: <a href="#" id="hapUserTitle"><%=((HAP.AD.User)Membership.GetU ser()).DisplayName %> (<%=((HAP.AD.User)Membership.GetUser()).UserName %>)</a>

Please advise what change and where in HAP do I need to do for HAP to work again.
I did try the setup page but that comes up with the same unauthorised page.
Thanks.

Open the web.config file, remove the authorization code for the setup.aspx page

In the browser go to setup.aspx and change the admin password

Brilliant. Thanks Nick, greatly appreciated. All working now.
