Is your EDGE server joined to the domain? If not I think you can ignore this error Deli

No My edge server is not joined to the domain but could you please explain this error.Thanks Deli

Some similar information can be found here http://support.microsoft.com/default.aspx?scid=kb;en-us;824217 Are you seeying this multiple times per minute in the eventlog or very sporadic. If this is sporadic I would not worry about it Deli

I see this error message repeating exactly after one hour.

Do you have a DNS server configured on your EDGE Server? It is probably your EDGE server that tries to authenticate to a remote DNS server but because he is not in a domain it cannot authenticate Ignore the message Deli

Yes i do have Secondary DNS server setup on my Edge serverThank u very much deli.
