    Some machines not getting dns

    Hey guys,
    Sorry i'm getting a sore head from this one.... So here goes... Server that does DHCP decided to crash out monday night, So came in tuesday restarted it, wasn't giving out ip addresses, Turned off the old wds that was on it, then bound the ip address so it could then give out ip addresses, then everywhere is getting IP addresses again... but now some machines are getting a usable dns and some arn't, We have 2 dns servers both seem to be happy(Can use nslookup on both of them and seems to resolve fine)

    Some of the machines (Doesn't seem to be a pattern what so ever) and when i say some we have 3 IT rooms that have 30 machines each that are doing as they should, where as some of them only get 3 working out of the 30(Whose that arn't working are receiving "there are currently no logon servers available to service the logon request")

    Now doing dcdiag /testNS does give me:
    Code:
    C:\Program Files\Support Tools>dcdiag /test:dns
    
    Domain Controller Diagnosis
    
    Performing initial setup:

    Address: 172.16.0.10
    
    > student-server
    Server: Unknown
    Address 172.16.0.10

    Just been playing for abit and one machine we had working fine, with the machine next to it (on the same switch and vlan) refusing to see anything not on the same vlan could ping machines on its vlan and nothing outside its vlan, then 5 minutes later the one that was fine has stopped being able to see anything not on its vlan, Hence i'm guessings its not dns related, looked at the logs on the switch there on doesn't seem to be any problems... And well its not just that switch its happening on, Anyone got any bright ideas i should be looking at? Think next step is wait till end of the day and restart the core switch.. ?

    **Looks like it was something really odd going on with the core switch, As a restart off that seems to have resolved the issues, Although we shall find out tomorrow**
