ZCC login fail

I have ZCM on VMWare environment. After migrating the Sels virtiual machine
via vmware tools, some problems with network card appeared.
This problems are been solved, but after this I'm not more able to log in
ZCC. I have this error:

Unable to connect to the ZENworks database. Please ensure that the ZENworks
database is running. One of the possible causes could be the database server
IP address changed. Please see the documentation for manual steps required
to fix the login issue associated with it.

My ZCM is running on SLES sp1 and is 10.1.2a version.

Thanks for help
