Hi, I have recently created new Child DC and transfered all FSMO roles to the new DC from old child DC. DHCP and DNS is also configured as per my old child DC. for testing when i shutdown my old child DC, outlook 2007 & 2010 clients get again & again password screen, asking for the password. even users are typing the correct password, again screen pop up's for password. I have also installed the all server's CA certificates to TMG, Exchange and new Child DC. When i turn on the old child DC, every thing become's back to normal. Can anyone please help me? Regards, Areeb

Hi Areeb, Make sure that your clients are pointing to the new DC as preferred DNS server, the new DC is also a Global Catalog server.Thanks and Regards, Mukesh. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Hi Areeb, Run ExBPA and check for any error. You can post in exchange forum http://social.technet.microsoft.com/Forums/en-US/category/exchangeserver Thanks.

Hi Mukesh, Thanks for your reply, Well all i have also setup Global Catalog server as per my old Child DC. Can you please clear, how i can point my clients to new Child DC. they are all are external users. Regards, Areeb Hassan.

Modify your DNS / Firewall settings to point to your new Child DC.Thanks and Regards, Mukesh. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Make sure your clients and Exchange server is using your new DC/DNS. Please post IPCONFIG/ALL from you DC, client and EX server here. “transfered all FSMO roles” -> Did you transfer all 5 FSMO role to this server or only 3 domain specific. Anyway, please post the result of Netdom Query FSMO also here.

Hi, Have you encountered other problems? If so, please describe the issues more clearly. If only Outlook cannot work, this issue can be caused due to Outlook has saved some information of the old domain controller. As a test, please create a new test domain account. Then, please configure Outlook for the new test user. What is the result? Thanks. Nina This posting is provided "AS IS" with no warranties, and confers no rights.

Hi NIna, Good idea, will create and try. Thanks a lot. Regards, Areeb Hassan.

Hi Santhosh, Yes i have transfered 3 FSMO roles Under Operations (RID - PDC - Infrastructure). Remain 2 roles are on our master DC. I have checked Exch.Server & clients are show correct DNS. Regards, Areeb

Hi Mukesh, New Child DC is its self DNS server as well, and my firewall (TMG) is pointing to new Child DC. Thanks, Areeb

What version of Exchange are you using? Did you verify the DSACCESS properties? Also, try restarting the exchange server.

Hello, please provide the requested output from "ipconfig /all" and "netdom query fsmo". These are essential information to help you with your problem. RPC errors as listed like 0x6ba belong to the firewall configuration between the servers, which you also didn't provide.
