Re: Cannot sign in to Administration
Did you make a backup of your Web.config file?
If you did grab the "machinekey" value in the backup file, replace that value in the existing web.config file. Then try to login with what you is the right admin account.
If that doesn't work... replicate (Domain A)'s credential.
1. Copy the machinekey from the web.config to the Domain B's web.config
2. Goto the Domain A's database and table for mp_Users, assuming that user names are the same ... all you have to do is copy the admin account's PasswordSalt and Password values.
3. Paste those respective values into the Domain B's database and table for mp_Users.
When you hit the web site again the app should pickup the changes to the web.config and restart automatically. Sign in with the credential from domain A .... that should works. LMK ...Great!
