Hi guys, I've got 2 problems: 1. I'm connected with my win XP Pro on a win 2000 server. Yesterday, evrything was working fine and today I'm unable to have access to the network. I still can access my mails (I receive a popup to log in but it doesn't recognize my password- I click cancel and then I can access my mails), I can access Internet through the server but I can't access the drives on the server. No changes has been done to the server! In event viewer I receive following messages: a. "System" "The Security System could not establish a secured connection with the server ldap/apollo.galaxy.step-a-site.com. No authentication protocol was available." "The Security System could not establish a secured connection with the server cifs/APOLLO. No authentication protocol was available. " b. application: "Windows cannot bind to galaxy.step-a-site.com domain. (Invalid Credentials). Group Policy processing aborted." "Windows cannot query for the list of Group Policy objects. A message that describes the reason for this was previously logged by the policy engine" 2. My win Xp doesn't shut down anymore. When I do so, it starts working (closing evrything except windows) and suddenly it stops. Nothing is blokked, If I want I can continue working on my pc. To shut down (or restart), I need to manualy reset my PC. This is a long message. But I really need help as soon as possible. Thx JJ
