A network service error has occurred

[Ale Negri]

I have just upgraded to Zimbra 7.1.1 and immediately after that I was not able to connect with the server. I have been trying to check for something not correctly mainteined from old to new version but without results.
I include in this message the details of the error.

Can anybody help me ?

Thanks in advance.

This looks like an error while looking up locations (e.g. conference rooms) for calendar booking. What type of accounts do you have configured in ZD; are they all ZCS accounts or do you have some POP/IMAP/Gmail/Yahoo accounts also? Can you say what you were doing when this error occurred?

I've only an IMAP account in ZD. The error occurs at the start up of ZD.
