Background: This box has been running solid for about 2 years now. last thursday users couldn't login. When i reset the DHCP service they could log in again and it would hang about 30 mins later. My work around was to give clients static addresses. It worked for about 8 hours. Current problem: Can't login with leopard client. I get "an error has occured". I then log in as local admin and remove the system from the directory and re add it. I also went back to DHCP. On reboot the system will see the other network users and log in fine. about 10 minutes later on reboot the login screen just displays "admin" and other "other users" i can then enter the shortname and pass word and it logs in. Then about five mins later on the next reboot same login screen but it says "an error has occured" and will not let me in further. I can ping the server by name always (companyserv1.local) from client. the open directory says the server is responding normally. when i log in when looking at the hard drive on the left where it lists network names i click on the server listed and it says "not connected" when i click on connect as it does nothing. Server config: (DHCP general)ip range 192.168.2.20 to 100.. router 192.168.2.1... server 192.168.2.200....(DNS tab) default domain company1, name servers 192.168.2.200 (DNS general) allow zone transfers and recursion.. (Zones tab) name company1.. primary name server companyserv1... primary name server address 192.168.2.200.. (AFP general) enable bonjour registration and enable browsing with appletalk (AFP access) authentication standard.... enable guest access, secure connections, and admin to masquerade. (OPEN DIRECTORY general) role is open directory master appletalk is enabled on server en0, configured auto. Client Config: client is set to dhcp and its dns is 192.168.2.200 and search domain is company1. It has the open directory server added "companyserv1" and has ldap3 installed and on auto config. Any ideas?
