If the above did not work then on netserver2 server at a command prompt run:<br />
<br />
dcdiag /v &gt;&nbsp;dcdiag.txt<br />

Read the contents and post what things are failing. &nbsp;There are a couple things that could cause that error. &nbsp;Make sure the time on both servers is synchronized and there is not greater than 5 mins difference as well. &nbsp;Let me know the result of the command above and I can help further.<br />

I am having an issue where two Windows Domain Controllers do not appear to be "talking".  I have two DCs: Netserver1 (running Windows Server 2008) and Netserver2 (running Windows Server 2008 R2).  I am getting the following attached error on Netserver2:  KRB_AP_ERR_MODIFIED error from the server Netserver3$.  Any assistance on correcting this would be appreciated.
