Peeps, our fileserver has gone offline twice in two days. So nobody could connect to the mapped drive on this server or print.

In the event viewer there are two recurring errors:

The kerberos client received a KRB_AP_ERR_MODIFIED error from the server IT-PC11$.  The target name used was cifs/HP19698124141.matches.com. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named  machine accounts in the target realm (MATCHES.COM), and the client realm.  

Second error:

The driver detected a controller error on \Device\Harddisk1.

Any ideas on what I should do?

Thanks
Yashy

Did you make any changes in your domain environment last days? File/Print Server DNS rename, IP changes ?

I had this problem once before and it was a problem with Windows Firewall. If you have Windows Firewall running on the server the disable it and see if it starts working again

Didn't make any changes at all to our environment no. We merely maneouvred servers from one place to another and that's all. No IP changes or renaming of DNS. And there's no Windows Firewall on.

check in revers lookup zone on DNS server if there is entry for File/Print server (just in case).

Thank you in advance.

iSiek, there was no entry for DNS on reverse lookups:). I've just added it. Would that have caused issues?

I mean, the server has frozen over the past two days and been really slow and I wonder whether the second error mentioned also has anything to do with that? (i.e. disk error)

Thanks again

yes it could. It is required to resolve IP to hostname for some services :)
