I messed up somehow with my samba server.

I'm trying to access a linux share from windows and the log on the linux server says:

[Unspecified GSS failure.  Minor code may provide more information: Request ticket server cifs/myserver.mydomain.local@MYDOMAIN.LOCAL kvno 8 not found in keytab; ticket is likely out of date]

How can I fix this?

Thank you.
