Azure File Shares that just mount and work.
Access-denied errors, permission tangles, and shares that won't connect are almost always fixable. We get your SMB file shares mounting cleanly, secured by identity, and syncing the way they should.
Get shares working — and lock them down.
Azure File Shares should be simple: an SMB share in the cloud your team maps like any network drive. In practice they trip people up — a share won't mount, a user gets "access denied," or permissions work for some folders and not others. The usual culprits are a blocked port, the wrong authentication method, or the gap between share-level and file-level permissions.
We sort out the whole chain — connectivity, identity, and permissions — then make it secure and durable: identity-based access, least-privilege permissions, private connectivity, and protected snapshots. If you're using Azure File Sync to bridge on-prem and cloud, we get the sync groups and cloud tiering behaving too.
The full chain, not just the symptom.
Most "it won't work" tickets are one of these — and they interact, which is why guessing rarely fixes it.
Mounting & connectivity
The classic blocker: port 445 filtered by an ISP or firewall. We confirm the path, use private endpoints where needed, and fix drive-mapping that won't reconnect at logon.
Identity-based auth
Move off storage keys to on-prem AD DS or Microsoft Entra Kerberos authentication for hybrid identities — so access is tied to real users, not a shared secret.
Permissions that make sense
The part everyone gets wrong: share-level RBAC and NTFS (directory/file) permissions are two separate layers. We set both correctly so "access denied" (0x80070005) goes away for good.
Azure File Sync
Sync groups and server endpoints configured properly, with cloud tiering tuned so hot data stays local and cold data lives in the cloud — without the sync conflicts.
Performance & tier
The right tier for the workload — Standard vs Premium (provisioned) — so latency-sensitive shares perform and everyday shares don't overspend.
Protection
Share snapshots, soft delete, and backup so a bad sync or accidental delete is a quick restore, not a lost afternoon.
Sound familiar?
If your file shares are misbehaving, it's almost always one of these — and we've fixed each of them before.
- Share won't mount from the office network
- "Access denied" for some users or folders
- Mapped drive drops on every reboot
- Still authenticating with a storage key
- Azure File Sync conflicts or tiering issues
- Slow performance on a busy share
Azure File Shares, answered.
Why can't I mount my Azure file share?
The most common cause is TCP port 445 being blocked by an ISP or firewall, which SMB needs. We confirm connectivity, set up a private endpoint if required, and check that the client OS supports the required SMB version and encryption.
What's the difference between share-level and NTFS permissions?
They're two separate gates. Share-level permissions are Azure RBAC roles that decide who can reach the share at all; NTFS permissions control what they can do inside it, folder by folder. Access works only when both line up — misreading this is the number-one cause of "access denied."
Should I use AD DS or Entra Kerberos authentication?
It depends on your identity setup. Traditional on-prem Active Directory Domain Services (AD DS) suits environments with domain-joined machines; Microsoft Entra Kerberos fits hybrid identities and Entra-joined devices. We assess your estate and set up whichever fits — done right, users authenticate seamlessly.
