Version my NAS is : DSM 5.0-4493 Update 5

Please give me some advice how I can fix it.

Solution

Try to either reset the account on the NAS in the domain or delete it. Sync the AD DCs. Make sure DNS on the box defined as one of the DCs.

Why aren't you running DSM 6? Did you do any windows updates recently to your DCs?
