DNS issue amongst other things

[mirojr]

Hello,

 

Am having problem with mixed environment, a DC running 2003 std and one running 2008 r2

 

The error seemed to occur when i was trying to run ad authentication from a linux box using kerberos.

 

I managed to solve problem once, or so i thought by resetting pasward with netdom.

 

The a day later i ran authentication on linux(not knowing that was the cause) and all the UNC shares stopped working.

 

DNS seems to be mucked up.

 

how can i diagnose and fix my network

 

please i am up the creek here

 

thanks

The linux box is probably the problem. It may have been acting as a DNS and/or DHCP server. Check the event logs Windows servers specifically the domain contoller.

The linux box has never had DNS running as a service, neither has it had dhcp.

Kerberos tends to fail if machines times are at an offset of more than 5 minutes, are you running your servers from a common NTP server to ensure this is not the cause? Just a suggestion.
