Hi Matt!
Are you able to access the resources using My Network Places in Windows?
Are you performing redirect restore of Master database?
If yes, then please note that,redirect restore of Master database is not supported.
As the master database stores all the information pertaining to SQL databases including the users created ones.
If the master database and other database were restored to a different location, the pointer within the master database would point to the original location of the databases that has been changed now.
If no, then verify that the server name and the drive are the same as they were at the time of backup.
Do revert back with details.
