If network locations aren't appearing or working correctly, follow these troubleshooting steps systematically.
Issue 1: Network location not appearing
Check if the GPO is linked to a user OU (not computer OU):
gpresult /scope:user /v
Verify the user is in the correct security group for item-level targeting:
whoami /groups | findstr "Department-Users"
Issue 2: Access denied errors
Test manual connection to verify permissions:
net use \\fileserver\department
If this fails, the issue is permissions, not Group Policy. Check NTFS and share permissions on the target folder.
Issue 3: Connection not persistent
Verify the "Reconnect" option is enabled in your GPO and check for conflicting Offline Files policies:
reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CSC" /v Start
If the value is 4, Offline Files is disabled, which can cause persistence issues.
Pro tip: Use the Group Policy Results Wizard in GPMC to simulate policy application for specific users and computers before deployment.
Verification: All network locations appear correctly, are accessible, and persist across logons without errors.
