I have 4 different domains in four different locations.
HeadOffice main.local - win2008
Branch1 Office domain1.local - win2003
Branch2 office domain2.local - win2003
branch3 office domain3.local - win2003
Head office has IPsec VPN between each branch. From head office i can ping each branch's domain controller by IP address (not by name)
I want to establish domain trust between head office and each branch.
I opened DNS (head office main.local) and wanted to add forwarder but it times out and is unable to resolve.
Any idea why ?
do i have to open any ports on firewall ? ( head office has CISCO ASA 5510 and each branch has CISCO 800Series ADSL router)
