I'm trying to connect from a Windows 2008 server to Windows 2003 using WMI, however, each time I get access denied. There is no firewall between the servers, no hardware or software. The account is a local administrator account, working using RDP - and working from another Windows 2003 server.

The account is a local account, the server is not connected to a domain.

However, from Windows 2008 I get "Access Denied". Besides firewall and lack of credentials, which is not an issue, what other setting might be causing this?

Best Regards, Anders

How are you connecting? (powershell, vbscript, some WMI tool?) What are you specifying for your impersonationLevel and authenticationLevel? – Simon Catlin Sep 10 '12 at 21:01
@SimonCatlin Cheers mate for the comment and additional questions. However, I got it working, see answer below. – Anders Sep 11 '12 at 20:27

Not like answering my own questions but a solution was found, the authentication level. The Windows 2003 server as forcefully requesting NTLM2 while Windows 2008 was sending NTLM.

A change in the "LAN Authentication"-parameter in the local polices made it work.
