Hi Techspot staff, I'm having so much trouble with this Microsoft application. This app has two ways for authenticating one of them is by using a domain account and the other is by using an SQL Server user. As I choose SQL Server authentication SQL Server hangs for a lot of time even without entering user or password, I'm suspecting of something in any Windows service since I try the same conection to the same server from KingSoft Office (a Kind of MS Office) and it connects really fast. I had a look to the resource monitor and it is waiting for lsass.exe, and it is waiting for svchost.exe and it is waiting for some network resource. The thing is that I'm not aware of what's happening with Windows when SQL Server hangs. Is there any way that you could help me to discover which could be the problem. Thanks in advance! Oscar.
