HOw do I get write access to shared drive volume (permissions are set to read and write)?

Hi rightSpace Support,

Here is a check list to work through, it was written by AI so I hope it helps.

1. NTFS Permissions

[ ] Right-click folder → Properties → Security tab → Confirm user/group has Write or Modify.

[ ] Use icacls or Get-Acl to audit permissions:

powershell

icacls "D:\SharedFolder"
Get-Acl "D:\SharedFolder" | Format-List

[ ] Check for Deny entries or inherited restrictions.

[ ] Confirm group membership propagation (logoff/logon or klist purge).

🌐 2. Share Permissions

[ ] Right-click folder → Properties → Sharing tab → Advanced Sharing → Permissions.

[ ] Ensure “Everyone” or specific users/groups have Change or Full Control.

[ ] Avoid relying solely on “Everyone”—use domain groups if possible.

🧠 3. Effective Access

[ ] Use Advanced Security Settings → Effective Access tab to simulate user access.

[ ] Confirm actual permissions match expectations.

🔄 4. SMB Protocol & Session Info

[ ] Check SMB dialect negotiation:

powershell

Get-SmbSession | Select ClientComputerName, Dialect

[ ] Confirm SMB1 is disabled (unless legacy clients require it):

powershell

Get-SmbServerConfiguration | Select EnableSMB1Protocol

[ ] Ensure SMB signing/encryption policies aren’t interfering.

🔑 5. Credential Conflicts

[ ] Confirm remote user is authenticating with correct domain account.

[ ] Use net use to inspect active connections and credentials.

[ ] Clear stale mappings:

cmd

net use * /delete

🧱 6. Firewall & Network Restrictions

[ ] Ensure TCP ports 445 and 139 are open between client and server.

[ ] Check Windows Defender Firewall rules for File and Printer Sharing.

🛡️ 7. Antivirus / Endpoint Protection

[ ] Review logs for blocked write attempts.

[ ] Temporarily disable protection to test write access.

🧭 8. Group Policy & Security Settings

[ ] Audit GPOs that affect network shares, SMB, or user rights.

[ ] Check for lockdown policies or restricted access tokens.

🧪 9. Test from Alternate Client

[ ] Try accessing the share from a different machine or user account.

• [ ] Compare behavior to isolate client-side vs server-side issues. 1. NTFS Permissions
