When making a database connection using direct connect or making a database server connection to an established ArcSDE personal or workgroup geodatabase, the following error message is displayed:
"Failed to connect to the specified server. The destination string buffer is too small."
The connection string for the server parameter is longer than 31 characters.
The information passed as the connection parameter for server is a combination of server name and database instance name. The server name and database instance name are separated by a period. Where the backslash usually separates the server name and instance name for SQLExpress there is an underscore. For example, server carolina with a database instance of carolina\sqlexpress is sent under server name as the following: carolina.carolina_sqlexpress
