Our server crashed yesterday and I had to take the .mdf file and put it on another server.<br />
<br />
Now when I login I get the following error:<br />
<br />
Server Name: 192.168.1.155<br />
Error Number: 18456<br />
Severity: 14<br />
State: 1<br />
<br />
Is there something I need to reset to be able to login to the database again?
