Critical: LDAP: query DNS result DNS Hard Error looking up e

I am not having any luck when trying to connect to all 3 of our LDAP Servers...I get this error in the logs:

Critical: LDAP: query DNS result DNS Hard Error looking up MyServer.Mydomain.com (A): NXDomain

It is open through our Firewalls. I don't even see the Test Query reach our Firewalls...any suggestions what I am doing wrong?

We were using Surfcontrol and it worked fine... :?:

Failure

Can your IronPort resolve the names of your servers, the error you posted looks like DNS is failing to resolve the LDAP server names, try using just the IP addresses of the server in your LDAP query.

Thank you

...I will try that in the Morning and let you know

a different error when using the IP

Action: drop or bounce (depending on listener settings)
Reason: no matching LDAP record was found

In Surfcontrol I put the IP without the DN and the query returns all the users.

In IronPort when I put the IP without the DN and do an Accept query using my email address in the Recipient Address I get the above error.
