License Issue with SBS Server

Hi All, We are facing a small problem in the above client license while installing it in the new server Old Server – SBS Server 2003 with Navision Version 4.0 build 20942 New Server – SBS Server 2003 Service Pack1 with Navision Version 4.0 build 20942 The client is using this license in the old server for long time and now they are facing problem with the same license when they deploy this is in new server. What could be the reason for this? When I start the server from command prompt I am getting this error. “The program is not valid for this Operating system”. Regards Ramanath .M

Are you talking about the native server or about a SQL server ?

Its Native database. But they have SQL granule in their license.,business,server,business,server So it should work. Maybe you can try to uninstall and reinstall the server service ?
