We have a 2012 R2 server which cannot browse its own shares. This server has been running without issue for a couple of years, and this started a couple of days ago.
When it tries to access one of its shares it gives the error "Share is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The specified network name is no longer available."
Other PCs can browse the server's shares without issue, using the same domain account.
Windows firewall is off, network discovery is on, SMB v1 is on. I've tried adding a new share with Everyone permissions and I can't access that either. I'm at a loss as to what the issue could be!
