I’m using SQL Server 2012 and I’m stuck with a strange problem.

I tried to restore a database snapshot to a database. Usually it doesn’t take much time to restore, but now it took 5 minutes and is still restoring, so I stopped query execution. It was trying to stop the query execution for more that 5 minutes, so i closed SSMS using task manager.

Then I tried to kill the restore process using KILL.

enter image description here

Now I am able to can connect to that server, but the list of databases is not opening. I mean: whoever is connected to this server, they are not able to get the databases. When I checked the sysprocesses table, it is showing lastwaittype as LCK_M_S.

None of my users can see databases. Looks like I kind of messed up. I cannot restart SQL Server as others are connected to the server.

How do I solve this? Please help.

EDIT:
i tried this approach and when i checked with

select db_name(dbid), * from sysprocesses where blocked <> 0

i got two records,

do you think because of these two rest of the process are getting locked up.

    I’m guessing there still is some hidden lock on the sysdatabases table in the master database. This could very well be caused by the KILL of the restore command.

    The article here might help you:

    http://ellisweb.net/2012/02/clearing-out-a-mysterious-table-lock-lck_m_s-in-sql-server-2008/

    It basically advises you to identify where the hidden lock is coming from, and then issuing a KILL on that process ID.
