Databases going in recovery mode I am in a weird problem. Firstly some information about our env.
We have around 50-55 servers and around 100 instances on them.
Backups are configured through netback and that is using Nt Authority\System account.
Everything is fine for the 99 instances but in one whenever we enable this account to login some databases go in recovery state.
And when we disable the account than we can recover it with normal restore with recovery.

Any pointers will be highly appreciated.
In error log it's saying: FCB open failed: could not open file
  "\sharepath" for file number 1 OS error: 32 the process cannot access
  the file as it's being used by another process


System account has issues with accessing database files on network share 

Can you, perhaps, try this?:


grant full access of [domain\serverName$] to
\\sharepath\sharefolder where database files resides
trace if there any open handles to those file, that prevents database to be started
