Troubleshooting

Network path not found: Error code 35/53

Cause

This error occurs when the PDC's SYSVOL share is not accessible from the ADAudit Plus server.

Troubleshooting

1. Ping the PDC by its flat name and fully qualified domain name (FQDN) from the ADAudit Plus server.
   • Open File Explorer on the ADAudit Plus server and access the SYSVOL folder using your PDC's flat name and FQDN (\\PDC Name\sysvol).
   • If you are not able to access it, append the DNS suffix on the ADAudit Plus server either by adding an entry in the Advanced TCP/IP Settings or by adding a host record on the DNS server and mapping this name to the server's IP address .
2. Ensure that the RPC ports (static port 135 and dynamic ports 49152–65535) are open. Follow this port guide to open the required RPC ports.
3. Enable the agent-based GPO watcher to avoid all network errors:
   • Open ADAudit Plus.
   • Go to Admin > Configuration > GPO settings changes.
   • Enable the Watch via agent option.
   • Click Save.

Network access denied: Error code 65/41

Cause

This error occurs when the configured user does not have read access to the SYSVOL folder.

Troubleshooting

1. Enable hardened UNC paths:
   • Confirm that the user configured in the ADAudit Plus console has read permissions over the following share: \\<PDC Name>\SysVol\<Domain Name>\Policies\
   • If they have read permissions, open the Local Group Policy Editor on the ADAudit Plus server (gpedit.msc).
   • Go to Computer Configuration > Administrative Templates > Network > Network Provider.
   • Double-click Hardened UNC Paths and click Enabled.
   • In the Options section, scroll down and click Show.
   • Add the following entry:
     • Under the Value name column, type the following:\\*\SYSVOL
     • Under the Value column, type the following: RequireMutualAuthentication=0,RequireIntegrity=0,RequirePrivacy=0
   • Click OK.
2. Enable the agent-based GPO watcher to avoid all network errors:
   • Open ADAudit Plus.
   • Go to Admin > Configuration > GPO settings changes.
   • Enable the Watch via agent option.
   • Click Save.
