RE: [ActiveDir] DMZ and Trusts

[Guest, Mike]

Title: Message

David,   The solution you require is documented by Microsoft as the “perimeter network scenario” in the following Microsoft  document   http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/directory/activedirectory/fedffin2.mspx   One gotcha is that your admin staff have to have accounts in the DMZ domain as well as the internal domain, as you can’t assign a foreign security principal to a global or universal group in another forest – which precludes making your internal domain accounts into enterprise or domain admins in the dmz forest.   Hope this helps   ______________________________________________________ Mike Guest | Capgemini | Sale Server Support | Outsourcing UK Office: + 44 (0)870 366 1814 | 700 1814 | [EMAIL PROTECTED] 77-79 Cross Street, Sale, Cheshire.
