Hi Experts,<br />
<br />
We recently migrated our AD from Windows 2003 to Windows 2008.Basically, we decomissioned all Windows 2003 server Domain controllers, and promoted 30 Windows 2008 DCs.<br />
<br />
In the last few days, we are seeing LDAP failures in several DCs,and we have to reboot a DC <br />
to a temporary fix. We ran DCDIAG,NETDIAG,and all test passed, but we are seeing multiple LDAP issues<br />
<br />
Can anyone explain how to fix this issues?<br />
<br />
How can I know if my AD database is compromised?<br />
<br />
Thanks in advance<br />

Hi Experts,

We recently migrated our AD from Windows 2003 to Windows 2008.Basically, we decomissioned all Windows 2003 server Domain controllers, and promoted 30 Windows 2008 DCs.

In the last few days, we are seeing LDAP failures in several DCs,and we have to reboot a DC 
to a temporary fix. We ran DCDIAG,NETDIAG,and all test passed, but we are seeing multiple LDAP issues

Can anyone explain how to fix this issues?

How can I know if my AD database is compromised?

Thanks in advance

Windows 2008 LDAP issues

Databases are organized collections of data, most commonly accessed through management systems including schemas, tables, queries and processes that allow users to enter and manipulate the information or utilize it in other fashions, such as with web applications or for reporting purposes.

Databases

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Active Directory (AD) is a Microsoft brand for identity-related capabilities. In the on-premises world, Windows Server AD provides a set of identity capabilities and services, and is hugely popular (88% of Fortune 1000 and 95% of enterprises use AD). This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
