If you have a Citrix XenApp environment and change your SQL server, you will need to edit your mf20.dsn with the new server name. Located at:
C:\Program Files (x86)\Citrix\Independent Management Architecture\mf20.dsn
If you changed your SQL credentials, you will need to specify the new user name as well here. If you just change the password only and nothing else, you don’t need to edit your mf20.dsn file. But you will still need to set the new password or the IMA Service won’t start.
Once you make whatever changes you need to the mf20.dsn or not if it’s just a password change, do the following:
1. Go to Services and stop the IMA service (Citrix Independent Management Architecture) if it is still running.
2. Open command line and Navigate to:
C:\Program Files (x86)\Citrix\Independent Management Architecture
dsmaint config /user:yourdomain\youraccount /pwd:yourpassword /dsn:"C:\Program Files (x86)\Citrix\Independent Management Architecture\mf20.dsn"
4. Restart the IMA Service
5. You can also recreate the local host cache database (LHC database) if you have issues starting the IMA service after this. Type:
then restart the IMA Service. It will populate the cache immediately with info from the datastore.
