SBS - Trend Worry Free Business Security Event ID 537

Over all, we have been quite happy with the Trend Micro Client/Server/Messaging SMB product.

It installs fairly smooth on the server and relatively smooth to the clients.

In one case, we have upgraded our client's SBS server and the client machines to the new version of the product called Worry Free Business Security.

This is the first SBS box that we have done this on with others to follow.

Since the upgrade, we are seeing the following in the morning reports:

Security Event ID 537: An error occurred during logon.

Notice that there are a lot of them.

The only indication that we are dealing with a Trend problem is from the Microsoft SBS newsgroup here: Failure Audit 537 in Event Log. Our circumstances are identical to the newsgroup poster.

So, we too have opened a trouble ticket with Trend to further investigate the problem.

For now, we will not be upgrading any further SBS boxes.

The "fix" is in this post: SBS - Event ID 537 NTLM Logon Errors Solved - Sorta.

It is pretty silly, and a real blunder on Trend's part.

We have since walked away from Trend and their products.
