Means your SQL server is not working. Check to make sure it is started. Or your network is dropping connection. Does not look like it’s a Sambapos error.

[Khaleel_Rasakh]

I think sql is working because other client doesn’t has issue. Working fine

[Khaleel_Rasakh]

Only this system has issue,
I have doubt. I connected caller id module to the system, n rdp also. Is that make an issue??

[Jesse]

The error log you posted specifically says it cannot connect to the SQL server. I am not making guesses I am telling you what your issue is.

[JTRTech]

@Khaleel_Rasakh

Only this system has issue,

While kendash sugested the SQL server, a connection issue can be any number of things inc firewall, networking etc. It doesnt have to be a server side issue - if you pull the lan cable yourll get a similar error

@Khaleel_Rasakh

Maximum number of retries (5) exceeded while executing database operations with ‘SambaExeuctionStrategy’. See inner exception for the most recent failure.

Thanks for your support and I will update you.
