LDAP query DNS result DNS Soft Error?

I started seeing this error after we upgraded our ironport from a c100 to a c160. We see the error only once or twice a week.

-----------------------------

Error Msg:

The Critical message is:

LDAP: query DNS result DNS Soft Error looking up DC1.Domain.com (A) while asking Internal Resolver. Error was: Request timed out.

---------------------------------

This DC server is a Win Server 2003.

We also have a new Win Server 2008 R2, but the domain is still at a 2003 level.

The LDAP Query tests pass.

Anyone have an idea?

Thanks

Hello Jerry,

in your LDAP server profile: are you using the hostname of the DNS server (which needs to be resolved via DNS) or are you usingthe IP address? I assuem you're using the hostname and it seems that the DNS server cannot resolve it to the LDAP server IP fast enough which results in the error message you see. I'd then recommend to use the IP address instead of the hostname in your LDAP server profile configuration to avoid this.

Thanks and regards,

Martin

Thanks

I'll give it a try.

I have not seen the problem occur yet. Hopefully all is fixed.
