You need to look at what if anything has changed recently.  Has the authentication method been altered?

Has this worked for you in the past?  If so, again, what has recently changed?

Ok. What changed last week?  Something with authentication, permissions, firewall, etc.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Did you check the database in sql server? Is it online , error 823 means there is some issue with file, check the G:\ drive available on server after reboot , if it is there check "XDS.MDF" file exists at location

From error you are getting, it looks like you lost SQL connectivity or database. You need to focus on your SQL server. Check Lync logs, you will see connection errors to SQL or backend db.
