Leave new shaik January 28, 2015 12:37 amHi Experts. I have got the error "a network related or instance specific error occurred sql server 2012 ". I have enabled tcp/ip, restarted the services. The sql server service is getting stopped even after the manual restart. I have checked in event viewer and I noticed a error. Here is the error The log scan number (43:456:1) passed to log scan in database ‘model' is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during startup. Event Id 9003.Please suggest me the solutions to solve this. TIAReply Pinal Dave January 29, 2015 9:07 pmLo

I had the similar setup working when i was using a standalone SQL SERVER in the same LAN, however the new SQL server is in a clustered environment and my Moneris API is not able to make a connection to the SQL SERVER. If i try it from the same LAN everything works fine. The issue only occurs when accessing it from different LAN. When i debug the application i get the following: " Error getting data from DB: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
