I bought a gigabit NAS to replace my existing 100Mb NAS200. After copying the data and users from the old box to the new (during which both NAS boxes worked fine) I renamed the old one to BACKUP and gave the new one the name of the old, FILE_SERVER. After that the old NAS is no longer accessible from my Vista-laptop I can ping it using IP and name and access the web interface but not access shares (Windows cannot access \\backup, Unspecified error 0x80004005) nor create a drive mapping (The specified network file name is no longer available)The new NAS is a Synology DS211 with DSM3.2 and 2 3Tb drives, the old one a Linksys network storage system with 1Tb drive. I didn't change anything on the NAS, except from its name. I dit reset the network settings by pressing Reset for 2 secs and I did reset the password on the old NAS to match my Vista password (same username), just to be sure - it was the same already. I checked everything, services, network config, credentials. Everything is okay and yet I cannot connect. Any suggestion anybody?
