[CLIENT: XXX.XXX.XX.XXX](where XXX represents Ip address of client machine)After that the client machines are not getting connected to sql server. Actually I have 2 applications connected to the same sql server. One is working perfectly fine while the other is not able to connect. Both the applications are connected through sa. Can someone please help me to solve this issue.Note : SQL Server version is SQL Server 2005 standard Edition with SP2 Post #570042 GilaMonsterGilaMonster Posted Tuesday, September 16, 2008 4:30 AM SSC-Forever Group: General Forum Members Last Login: Today @ 2:03 PM Points: 45,423, Visits: 43,755 State 16 means that the default DB or the DB requested by the login is not available. Check what DB the app in question wants and make sure that it's accessible (present and online)Why are your apps using the sa login? It's a security worst practice.In the future, please post SQl 2005-related questions in the SQL 2005 forums.
