Few days ago users start to complain that nobody can connect to the database located on the server.<br />
So I start with the basics.<br />
Verify that all the Act and SQL services are start it on both the client and the server. Make sure the Act sync is running on the server.<br />
I reboot both server and client machine.<br />
I move the database from the server on the local client machine to test it locally.<br />
I even install Act on the server where the database reside. I also restore the Database from backup like few days before all this happens. Still the same error no matter from where I try to run it.<br />
