I am stumped on this one. On SBS 2003, the 16 MB application log fils up with loads of 8026 and 8031 event IDs ovr just a couple minutes - hundreds of 8026 then hundreds of 8031 then it repeats.
Then the server freezes up / people can't access the shares and we reboot it. then it runs fine for a few days (3 - 8 days - it varies) and the problem reoccurs
The text for the errors are:
Unable to open LDAP session on directory 'SPOCK.domain.local' using port number 389. Directory returned the LDAP error:[0x1] Operations Error.
LDAP Bind was unsuccessful on directory SPOCK.domain.local for distinguished name ''. Directory returned error:[0x51] Server Down.
EventID.net talks of more complex systems than ours (just a single SBS server) and / or DNS errors that look OK when I look at the DNS server control panel.
any advice would be greatly appreciated.
