Secure TcpClientChannel with errors on XP SP2

I am trying to use secure TCP remoting between 2 XP SP2 machines which
are not joined to the same domain but constantly see the exception "The
server has rejected the client credentials.". I have been able to get
the same piece of code to work from XP SP2 --> W2K and W3K but cannot
on XP Pro or Home both running SP2. Below is the configuration files
for the Client and Server

Server
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.runtime.remoting>
    <application>
      <service>
        <wellknown mode="SingleCall"
type="LeastPrivilege.Demos.SecureRemoting.ImplementationClass, Server"
objectUri="server.rem" />
      </service>
      <channels>
        <channel ref="tcp" secure="true" port="8080" impersonate="true"
protectionLevel="EncryptAndSign"/>
      </channels>
    </application>
</system.runtime.remoting>
</configuration>

Client
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <system.runtime.remoting>
        <application>
            <channels>
                <channel
                  ref="tcp"
                  secure="true"
                  tokenImpersonationLevel="impersonation"
                  protectionLevel="EncryptAndSign"
                  servicePrincipalName=""
                  domain="XPMACHINE"
                  username="RemoteUser"
                  password="password"
                  />
            </channels>
        </application>
    </system.runtime.remoting>
</configuration>

I have created both the channels with ensureSecurity set to false but I
am absolutely stumped by this error.

Below is the Stack Dump

System.Security.Authentication.InvalidCredentialException was unhandled

Any help would really be appreciated
