One of the first steps, while you are trying to configure BizTalk Server, is to provide the “Database server name” on the BizTalk Server <version> Configuration page. So far nothing new. However, in one of my recent BizTalk Server installations where we were using a SQL Server that was configured with a non-default port (1433), we encountered this bizarre problem:
BTS2016LAB01, 3431 is invalid because it contains one or more of the following characters: `~!@#$^*()+=[]{}|;'”<>?.
Cause
Well, the reason is obvious for all but in this case, a little stupid considering the current days. Of course, we all can understand that the special characters are not allowed and we cannot use it.
But was not our case, we are not using any special characters in the Database server name and if you check carefully, we catch the error while configuring the Group, which means that we already were able to create the SSO database in the SQL Server – so the database name was valid/correct.
And if there were really special characters in the Database server name, then the configuration wizard should be smart to validate on the BizTalk Server <version> Configuration page and do not to continue with the configuration.
I personally consider this as a bug in the BizTalk Server Configuration Wizard tool because in our case the real problem and the cause of this error was that we had provided the database name with a space between the server and the port: “BTS2016LAB01, 3431”
Solution
The solution to this problem is simple, first of all, and obviously, you cannot use any of the following special characters: `~!@#$^*()+=[]{}|;'”<>?. under the Database Server Name.
In our case, the solution was simple also, we just need to remove the empty space on the Database Server Name: “BTS2016LAB01,3431”
