Hello
I understand the urgency of the situation with your SAS system server. Here's what I found that might help:
You can activate Windows Server 2003 over the Internet by following the steps provided in the Windows Server 2003 Guide, which includes opening the Activate Windows screen and selecting the option to activate over the Internet.
If online activation is not successful, phone activation is recommended. The process involves calling a toll-free number, selecting your country/region, and following the instructions to complete the activation.
Please note that while Windows Server 2003 is an older system and might not be supported for online activation, phone activation is usually a reliable alternative.
