Activated Windows Server 2003 Ent. asking to re-activate

[Guest Dmitry]

We are using Windows Server 2003 Enterprise as a Terminal Server. It was

installed and activated in 2005. This morning it would not allow any of the

users to log-on, and every user was presented with the Activation Wizard,

telling that the Windows needs to be activated before it can be used. The

Event 1000 was logged-on in the event log

 

Event Type: Error

Event Source: Windows Product Activation

Event Category: None

Event ID: 1000

Date: 10/1/2008

Time: 7:16:23 AM

User: N/A

Computer: FSDTS2

Description:

An error occurred while the wizard was checking the current Windows product

license. Error Code: 0x80040507

None of our users have the administrative rights to the server, so they

could not activate or de-activate the server. I have followed all the steps

in the Activation Wizard and the server was successfully activated. But our

production was down for 30 minutes this morning because of the activation

issue. I always was under impression that once activated, the server does

not need to be re-activated, unless the hardware changes. We did not change

any hardware or software in any recent time. My questions are:

- What can cause the activation to break?

- How can I prevent it from happening in the future

 

Thanks,

 

Dmitry
