Unable to Connect to SCCM/SQL Site Database

[ahmed226]

Hi,

 

3 weeks ago my SCCM Server/SQL Server was running fine and I was able to follow through with some tutorials here from this forum. I stopped using the machine for about 3 weeks. So today I hooked it back up, only to find that I am unable to connect to the site database when I click open the Config. Manager Console. It hangs and takes a long time trying to connect, Then I get the following error message:

 

The ConfigMgr console could not connect to the ConfigMgr site database. Verify that this computer has network connectivity to the SMS Provider computer and that your user account has Remote Activation permissions on both the ConfigMgr site server and SMS Provider computers. For more information, see "How to Configure DCOM Permissions for Configuration Manager Console Connections" in ConfigMgr Help.

 

also when i Click on SQL Server Management Studio, when i try connecting to the databse engine, it also does not work and I get this error message:

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. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)

Also I have been checking event viewer and I only see strange comments regarding DNS errors for example:

 

The description for Event ID 404 from source Microsoft-Windows-DNS-Server-Service cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

192.168.0.5

 

there several errors like this in event viewer but with no real error message except the annoying message shown above ^

can someone please help me? is there something i need to check?

 

thanks for your help

Not a SQL person but first thing that comes to mind is the SQL services running on the server...they may have stopped for some reason, an update etc...?

thanks for the tip. I tried starting these services but they did not and reason was because of a logon failure. I recently changed my domain admin password, and after that sql and sccm went dead. so i also updated sql server logon passwords then it worked lol, had no idea domain password would affect sql login.

You must have used it at SQL configuration time as the account for the SQL services. If any other services were configured using this account then they too will also have to be updated!!

Good idea to use and setup a service account with a cannot change password policy configured for such services as SQL!

I take it it's not the enterprise admin account that you are using, cuz that would defo be a bad idea..
