What should I do to fix the System error 5 issue?

On a network there are many systems connected with different operating systems. When a system running Windows XP tries to access another system using Windows Vista or higher using the Net View command, the ‘System error 5’ is generated. The primary reason behind this is permissions which are not granted to the XP system to access the Vista computer.

When full control to a system is not granted, the User Access Control (UAC) in Windows Vista also does not grant admin rights to local users automatically, even if the system is part of the administrative group. The main reasons for this system error 5 are:

  1. Time Synchronization Issues
  2. The account trying to access is disabled or doesn’t exist on the domain.
  3. Missing Permission to access remote computer

How to resolve System Error 5

To solve these issues you can try the following solutions:

Time Sync Issues – If both the Vista and the XP system are set to different time zones this error can occur. To resolve the time zone mismatch, you can follow these steps:

  1. Click Start and then click Run.
  2. Type cmd and click OK.
  3. At the prompt type NET TIME /QUERYSNTP.
  4. If it pops up an error then type NET TIME /DOMAIN /SET /YES.
  5. Also check to make sure that the Time zones are set properly.

This should solve problems with the time zones and should take care of the system error 5. If it doesn’t, then try the next solution.

The account is disabled– If the account you are using to access the system is disabled or if the password to the account is changed then system 5 error is generated. You can also check if both the systems are present on the same domain because if they are not you will get a system 5 error.  Try the next solution if this does not solve your issue.

Missing Permissions – To resolve the issue with permissions, check if the ‘Netlogon’ service is available on both the systems. If the service is available, then you can change some registry entries on the Vista system to get rid of the error. The steps to achieve this are:

  1. Click Start and then click Run.
  2. Type Regedit and click Continue to confirm admin access.
  3. Navigate to the key:
  4. Look for LocalAccountTokenFilterPolicy key on the right.
  5. Right-click it and then click Modify and change the value to 1.
    Note: If the key is not present you can follow these steps to add it:
  6. Click Edit, select New and then click DWORD Value.
  7. Type LocalAccountTokenFilterPolicy and then click OK.
  8. Right-click LocalAccountTokenFilterPolicy and then select Modify.
  9. Type 1 in the Value Data Box and click OK.
  10. Restart the system.
