Windows activation wizard will not generate an installatin id
I am having a strange issue on my Windows Server. I am using Windows Server 08 Enterprise and after several years of use I am getting the prompt to activate my Windows. I run the activation wizard and choose to use the automated phone system (because I am on a private network) and everytime the wizard will not generate an Installation ID for me to give the automated system. I have attempted to "change the product key" by re-entering my license key in hopes that it will clear this issue up. Is there a way to force the system to generate an Installation ID maybe in the command prompt. I would really hate to have to re-install Windows to fix this issue; this server is a Domain Controller and this would most likely cause my severe headaches to have to seize the roles, demote the DC, re-install windows, promote the server, re-join, re-gain the roles.....you see what I'm getting at here. There has to be a way to force the system to generate an Installation ID via command prompt. Any help would be greatly appreciated. I still have about 46 more days until I have to activate Windows so I have a little time to troubleshoot.

have you tried to enter the key and activate from the CL with
C:\Windows\System32\slmgr.vbs -ipk <product key> installs the product key but does not activate the server.
