A firewall that blocks TCP port 445, or TCP port 5445 when using an iWARP RDMA adapter, can also cause this issue. This indicates a problem with the underlying network or transport, such as with TCP/IP, and not with SMB. The specified I/O operation on %hs was not completed before the time-out period expired. I always receive the message 'The network path was not found' (Error Code: 0x80070035)Įvent-Viewer shows the event 30803 in the SMBClient:įailed to establish a network connection. Now i cannot access the SMB-Shares, neither the default admin shares, nor a newly created smb-share on a different drive for testing. I installed a new Windows Server 2016 (nano without GUI), added it to my domain, assigned my default GPO also applied on all my other servers, installed the fileserver with work-folders and deduplication. I have a problem and i'm troubleshooting since 15 hours. As soon as the SMB Client is disconnected the application running on the client crashes whilst it tries to reopen the handles. Nothing on Google just yet that I can find that relates to this error. So we can't seem to find a way to stop this happening. The server closed the session as part of periodic system cleanup. When checking the logs we find a key notification in the SMB Server Eventlog stating that the connection was cleaned up: Tried the keepconn setting in lanmanworkstation to 65535 in Registry The issue is that the session is being temporarily disconnected and therefore crashing the Database.Ĥ.

We have 2 Windows 10 computers, one acting as SMB Server and the other a client sharing an application that depends on an MS Access Database.

Have been trawling high and low to look at this issue and I know there are some other threads out there that discuss this, but not this specific issue.
