mwac.sys causes failure of network explorer Win10

Recommended Posts

I have been struggling for weeks to find out why my computer only shows 5 of the 9 computers on my Win2008R2 network.

Finally running network check on my windows 10 computer I was prompted that mwac.sys was causing an issue with the network.

None of this happened before my Premium Malwarebytes was upgraded to the latest edition 3.7.1.

I have seen somewhere that mwac.sys can cause problems with DNS and Active Directory. 

Is there a workaround or has this been addressed on a later release

I have tried the advice to add the internal loop (127.0.0.1) to the network card  on the Windows 2008 R2 DNS Server in IPv4. This is added under the actual DNS Server IP address.

It does not work.

If the workstation is rebooted still 5 of the 9 computers are not present in the network explorer.

If I stop Malwarebytes then click on network explorer all the workstations are seen.

We have Malwarebytes only on the machines that are active on the Internet and it is happening with every one.

Are there other suggestions?

Greetings,

This issue might be resolved by the new beta build of Malwarebytes, version 3.8.  You can learn more about it here.

If you decide you wish to give the beta a try then please open Malwarebytes and navigate to Settings>Application and scroll to the bottom of the tab where it shows the option to enable beta updates and select the option to do so and click Yes at the confirmation prompt then scroll back to the top of the same tab and click on the Install Application Updates button and allow it to download and install the new build, allowing it to restart your system if prompted to do so once the installation completes, making sure that you save anything you were working on before you do.

If you do try the beta, please let us know if it resolved the issue you were experiencing or not.

Thanks
