False Positive Alerts

Hello!

I installed for the first time Intrust agent on Terminal Servers.

I just can't find the reason why but :

I am receiving 2 specifics alerts from all my terminal servers (hundred of times per day).

The Alerts have been causing by the server computer name itself!

Here are the alerts : 

First to come is :

InTrust Major alert - Multiple failed logons by the same user.

There were 5 failed logons by user domain.com\MSTS-TAL1 from workstation MSTS-TAL1.

Alert was generated on computer msts-tal1.domain.com.

The Second Alerts is :

InTrust Major alert - Multiple failed logons from the same workstation.

There were 5 failed logons from workstation MSTS-TAL1.

Alert was generated on computer msts-tal1.domain.com

I just can't find what process or service causing that.

It's Happening every 10 minutes or so in every single Terminal Server.

What's best to do?

Is there a way to filter out the "computer":     "domain.com\SERVERNAME"      from this alert ?

IS IT a known false alert for terminal SERVERS that you know about maybe ?

Thanks inADvance ...
