My Win7 client has a connection to a Linux server and its shared folders. The problem occurs when the computer wakes up after a sleep and then one of the shared folders is not accessible. I receive the following message: Error code: 80070035, The network path was not found. I have problem with one specific folder only. When I restart the computer this problematic folder is accessible again. When I log off before sleep the folder is accessible after wakeup. If I try to access the folder by using the FQDN of the server or the server IP it is also accessible. As a temporary solution I mapped the folder to a network drive using the FQDN and it's working fine but it's inconvenient since every other folder is accessible on the server.

To summarize:

  • \server\problematicshare no longer works after resume (the Samba server sees my client connect, then disconnects a few seconds later while I receive the above error message)
  • \server\othershare works after resume
  • \fqdn.of.server\problematicshare always works
  • \ip.of.server\problematicshare always works
  • once the problem manifests, I'm no longer able to restart the "Workstation" service (it is not responding)
  • restarting the "Computer Browser" service has no apparent effect
  • the event log doesn't contain anything that seems relevant
  • "ping server" works
