Hi, We have configured the IAS Radius in windows server 2003 for VPN clients and we have registered it to the AD. While VPN user login to the domain , all the authentication and login will be stored in the Radius log. Now we want to configure the same for the windows servers which are not connected to domain. While local administrators and other local users login to the servers , entry should be added to the Radius log.

I think what you want is impossible to do.
Radius provide a way to authenticate against AD for clients using wifi, or VPN, ie remote access servers or appliance (access points, router ...) which will forward clients credentials to Radius server and gain answer from Active Directory to permit or not the access.

For servers that are not part of the domain, if an user logs on the server using local accounts (either users or administrators), the authentication process is done against the local SAM database, and there is no way to modify this behavior. More, IAS authenticate against AD users accounts (or computers accounts), but as local accounts are not part of AD, how do you want they authenticate?

What you want to do is impossible.
