    Exchange DNS Errors ID2013

    Morning all,

    I've been battling a funny error that has recently popped up on my exchnage box, and so far have drawn up a blank, so fingers crossed some may be able to lift the stone i haven't.
    Right the even log shows error 2013 and 2012 "SMTP could not connect to DNS server 194.238.48.3 the protocol used was UPD. It may be down or inacessable"

    Now, exchange is working fine, we can send and recieve.
    I can't ping the DNS server by IP from any of my machines
    However i can do a NSLookup using it
    Exchange is set to use these as external DNS serves and from my lasy check RM haven't changed them

    So thats it, i'm lost...any ideas?

    Thanks,
    Iain

    I've always setup our DNS to point to our dns server internally and from there your dns server has forwarders to the outside. In this case, I think you would still have the issue as it doesn't seem like the DNS server that you had is responding. I would try contacting your internet provider to double check what DNS servers they recommend using,

    Normally i would, but our e-mail is configured a little different. Basically we have a 100meg pipe for general internet vai C&W and our e-mail on a 10meg pipe from RM, so the exchange server needs to look at RM's connection and not the C&W one, if you get what i mean!

    I would still call RM then and double check if their DNS server's IP addresses have changed.
    Can you ping your DNS servers on your C&W side?
