I am having trouble connecting our software "Veritas Backup Exec" to our network disk, a Synology Disk Station (NAS). Veritas is running on a Windows Server.I can enter these in Windows Explorer. But I can't back up all data to nas Synology

Please have a look at the BE Admin Guide:

See the Note:

Before you create the disk storage on a network share, you must give read and write permissions to the Backup Exec service account. The Backup Exec service account is on the Backup Exec server that you want to access the network share.

Can you confirm that this was done?
