Hi, someone can solve this problem?

We have two DC on another IP network but still local. One
member server on the other segment. The member server can
talk at 100% to on DC, but it have un-authenticated
ldap_search error... this result in strange problem when
our server try make transaction with LDAP server.

Thank you for any help,

Frank
 
Hello Frank,

Thank you for your post.

Did you get this error from a Netdiag?

[WARNING] Failed to query SPN registration on DC '<DNS domain name>'.

Do you get a similar error with DCDiag (ex. Machine Account test)?

What events occur in your System and Directory Service Eventlog?

Hi Ben,

Yes, this is a Netdiag error and only when I run this
test on the other segment, on our member server. Localy,
on same DC, Netdiag can't find any error. Everything
look like healty DC server.

I use DCDiag and this time, we have:

['dc name'] LDAP bind failed with error 58

But, again, localy on DC, all test pass with success.

The communication between member server and second DC,
all test was a success with Netdiag and DCDiag from two
way; a mean localy on our member server and localy on DC.

Thank you for your answer,

Frank
