This is a gotcha that is hard to figure out, especially if you are trying to install and don’t have the documentation in front of you, because it is trying to install it!

In the documentation, it states:

Log on using an account that is a member of the BizTalk Server Administrators group.

Note  This user account must also be a member of the Administrators group on the SQL Server in which you will store BTAHL7 data.

This is normally an issue when you install it and it states: ‘The Specified account “###/###” is
invalid. Error code: Logon Failure: unknown user name or bad password.’
