Hello yaro,
Sorry for my late reply due to attendance of trainings these days.
Please apply the hotfix 931192 and 885887 for the client computer to fix the Event 40961 and 1030 error issue:
Users in a trusted external Kerberos realm cannot access resources from a Windows Server 2003-based forest to another forest by using a forest trust and a Kerberos trust
http://support.microsoft.com/kb/931192/en-us
You cannot access network resources after you try to log on to a Windows XP Service Pack 2-based computer

Please take your time to try.
Best regards,
