this exception

Client connection to WINMGMT needs to be encrypted for this operation.
Please adjust your IWbemServices proxy security settings and retry.

I try to set different setting in the connectOptions but the problem still
happens.

Any idea?

Thanks,

Larry

//set connection parameters for remote machine
connectionOptions.Username = adminUser;
connectionOptions.Password = adminUserPassword;
//connectionOptions.Authority = "Kerberos:" + Domain + "\\" +
serverName;
//connectionOptions.Authentication = AuthenticationLevel.Call;
//specify WMI path for remote machine
wmiPath = String.Format(@"\\{0}\root\cimv2", serverName);
return new ManagementScope(wmiPath, connectionOptions);

You must add the following code:
connectionOptions.Authentication = AuthenticationLevel.PacketPrivacy;
