Hello all,
I have AD running Windows 2000 !!...(upgrading sooon..;-). I have several branches....whereby in each branch i have a DC. PDC is in the main office.
sometimes we encounter issues over the network whereby the link between the main office and one of our branches is down. This affect the operations, business...etc because users are not able to login on their PCs using their domain credentials.
I want that when the link is down (bet the main and branch)...users are still able to authenticate and login using their domain credentials.
When the issue occurs, i have tested the followings in one branch:
- From a PC (either XP or Win 7) in the branch, PING the PDC in the main office = TIMEOUT, it's expected as the link is down.
- From a PC in the branch, PING the DC in the branch office, = reply OK from ping.
- I have checked the DNS entries on the PCs, it's ok. that the primary is the DC in the branch and alternate is the DNS server in the main office.
How to resolve this? that is allow the users to login/authenticate via the DC in the branch office when the link bet the branch and the main office is down.
Enabling Cache Logon will resolve this issue?? that enabling cache logon for the PC in the branches.
Great to help asap...
