Any other ideas here - for Trogan Crown heights office , they have a tablet that cannot access \\svr22 via unc - getting error "you do not have permission to access \\svr22" . I am able to access it via IP address though. I set hosts file entry for svr22 but it did not help.

**Network Error Dialog** on a Windows 10 machine states: *"Windows cannot access \\svr22 — You do not have permission to access \\svr22. Contact your network administrator to request access."* In the background, a second File Explorer window shows successful browsing to **\\192.168.1.200**, with shared folders visible: **apps**, **Data**, **Docs**, **netlogon**, and **sysvol**. The local machine shows **Local Disk (C:)** with **79.3 GB free of 118 GB**.

Also tried putting domain credentials manually into credential manager for the server , did not help either (but did help on another tablet!)

what kind of tablet?

Tech B 2025-01-16 21:50

what OS on it?

Tech A 2025-01-16 21:51

Tech B 2025-01-16 21:51

is smb2 enabled for both?

Tech A 2025-01-16 21:51

yes it is

Tech B 2025-01-16 21:51

have you tried accessing a share from another device?

Tech A 2025-01-16 21:52

I did, I had same issue with another tablet - tried all the steps above and it worked after. Not working on this other one though

Tech A 2025-01-16 21:52

oh no - didn't try accessing another share ,

Tech B 2025-01-16 21:53

thry to see if its the server or the device itself. It does look like DNS issue though

# Resolve SMB Access Denied Error When Accessing Server by Hostname

## Problem
A Windows 10 Pro Surface tablet cannot access a server share using the hostname `\\svr22`, displaying the error "You do not have permission to access \\svr22. Contact your network administrator to request access." However, the same share is accessible when using the IP address `\\192.168.1.200`. The issue appears to be DNS-related, as the server can be reached by IP but not by hostname. SMB2 is enabled on both devices.

## Resolution
This appears to be a DNS resolution issue rather than a true permissions problem. The following steps should be attempted in order:

1. Verify DNS resolution by running `nslookup svr22` from the affected tablet to confirm hostname resolution
2. Test accessing other shares from the same device to determine if the issue is server-specific or device-specific
3. If DNS resolution fails, check the network's DNS server configuration
4. As a temporary workaround, continue using the IP address `\\192.168.1.200` until DNS issues are resolved

Note that adding a hosts file entry and manually adding domain credentials to Credential Manager did not resolve this specific case, though the credential manager approach has worked on other similar tablets.
