Smb list file time8/22/2023 ![]() Windows Server has several built-in file copy utilities that you can run by using a command prompt. Ensure that the latest, most resilient, and fastest storage and networking device drivers are installed.Ĭopying files is a common operation performed on a file server. These might include SMB signing, client-side caching, file system mini-filters, search service, scheduled tasks, NTFS encryption, NTFS compression, IPSEC, firewall filters, Teredo, and SMB encryption.Įnsure that the BIOS and operating system power management modes are set as needed, which might include High Performance mode or altered C-State. Server: TSSv2.ps1 -Start -Scenario NET_DFSsrvĪccept the EULA if the traces are run for the first time on the server or the client.In this article SMB configuration considerationsĭo not enable any services or features that your file server and clients do not require. ![]() Start the traces on the client and the server by using the following cmdlets:Ĭlient: TSSv2.ps1 -Start -Scenario NET_DFScli Open the C:\tss_tool folder from an elevated PowerShell command prompt. Gather key information before contacting Microsoft supportĭownload TSSv2 on all nodes and unzip it in the C:\tss_tool folder. Because the process level permissions only apply to the current PowerShell session, once the given PowerShell window in which TSSv2 runs is closed, the assigned permission for the process level will also go back to the previously configured state.To verify if the change takes effect, run the cmdlet PS C:\> Get-ExecutionPolicy -List.Set the RemoteSigned execution policy for the process level by running the cmdlet PS C:\> Set-ExecutionPolicy -scope Process -ExecutionPolicy RemoteSigned.If the current PowerShell execution policy doesn't allow running TSSv2, take the following actions: We recommend the local machine RemoteSigned PowerShell execution policy.TSSv2 must be run by accounts with administrator privileges on the local system, and EULA must be accepted (once EULA is accepted, TSSv2 won't prompt again).DFSNs service and its configuration dataīefore contacting Microsoft support, you can gather information about your issue.SMB troubleshooting applies to fixing the file server connection. For previous versions of Windows, run command: ipconfig flushdns.In Windows 8 and later versions of Windows, use PowerShell cmdlet: Clear-DnsClientCache.This operation allows you to verify that DNS resolution is working correctly. To ensure that Windows will perform DNS resolution, you can flush the DNS cache after starting the trace and before reproducing the issue.It's possible that Windows won't attempt to contact a referral if there are other networking issues, such as a DNS resolution failure.Look for the DFS client to resolve DNS (assuming it isn't cached) and make a connection to a file server. Verify Active Directory works correctly to troubleshoot the DFS Namespace server.Make sure the Windows Firewall or another network security application isn't blocking the request.If the referral request arrives but no response is sent: The most likely cause is the traffic being dropped or blocked somewhere. Standard TCP/IP and firewall troubleshooting applies if the referral doesn't arrive. Verify whether the DFS Referral Request arrived at the DFS Namespace server. Skip to step 4 if the referral process completed successfully. The referral step has completed successfully if a referral list has been returned. The server should send a DFS referral response to the DFS client. Then, start the data collection steps over again. If no DFS referral is being sent, and there's no indication of a firewall or anti-virus block, restart the DFS client to clear any DFS referral caching. The client should send a DFS referral request to the DFS Namespace server. Look for the DFSC traffic in the filtered results or append the filter with DFSC in netmon or MA: tcp.port=445 and DFSC. The protocol is named DFSC by packet capture parsers. To do so, follow these steps:įirst, filter the trace by the SMB traffic for the DFS Namespace IP address. ![]() ![]() Troubleshooting checklistĮxamine the SMB traffic to see if the issue is with getting the referral list from the namespace server or connecting to the referred file server. Try our Virtual Agent - It can help you quickly identify and fix common DFS-Namespace issues.ĭistributed File System (DFS) Namespace is a Windows technology designed to provide distributed namespace access to file shares across an enterprise.
