Windows Server 2008 R2 Addressing Enterprise Needs Addressing User Needs Supporting IT Professionals Work Anywhere Infrastructure using Direct Access

DirectAccess Providing seamless, secure access to enterprise resources from anywhere

DirectAccess in Action

Benefits Of Direct Access Bringing the corporate network to the user Always-on access to corpnet while roaming No explicit user action required – it just works Same user experience on premise and off Simplified remote management of mobile resources as if they were on the LAN Lower total cost of ownership (TCO) with an “always managed” infrastructure Unified secure access across all scenarios and networks Integrated administration of all connectivity mechanisms Healthy, trustable host regardless of network Fine grain per app/server policy control Richer policy control near assets Ability to extend regulatory compliance to roaming assets Incremental deployment path toward IPv6

Always On Always connected No user action required Adapts to changing networks

Secure Encrypted by default Works with Smartcards Granular access control Coexists with existing edge, health, and access policies

Manageable Reach out to previously untouchable machines Allows remote clients to process Group Policies NAP integration for health compliance Consolidate Edge Infrastructure

Deployment Models

Deployment Scenario End-to-edge encryption No overhead of encryption on application servers Edge enforces machine/user authentication and data encryption Least change from customer’s existing edge deployments Trusted, compliant, healthy machine Windows 7 client Corporate Network Applications & Data (non-IPsec enabled) DC & DNS (Server 2008 SP2/R2) Internet Direct Access Server Server 2008 R2 IPsec ESP tunnel encryption using machine cert (DC/DNS access) Clear Text traffic from client flows through encrypted tunnel to Corporate network resources IPsec ESP tunnel encryption using UserKerb/Health Cert/Smartcard for broad network access

Deployment Scenario End-to-Edge Encryption + End to End IPsec No overhead of encryption on application servers (just authentication) DirectAccess Edge Encryption combined with End to End IPsec Server and Domain Isolation Trusted, compliant, healthy machine Windows 7 client Corporate Network Applications & Data IPsec-enabled Internet IPsec ESP-Null AuthIP Transport Traffic flows through encrypted tunnel to Corporate network resources Direct Access Server Server 2008 R2 IPsec ESP tunnel encryption using UserKerb/Health Cert/Smartcard for broad network access IPsec ESP tunnel encryption using machine cert (DC/DNS access) DC & DNS (Server 2008 SP2/R2)

Deployment Scenario End-To-End IPsec Transport Encryption Thin edge solution using IPsec Denial of Service Protection (DoSP) Service only allows Ipsec & ICMP traffic Full End to End IPsec Encryption IP-HTTPS tunnel used for proxy scenarios only Trusted, compliant, healthy machine Windows 7 client Corporate Network Applications & Data IPsec-enabled Internet IPsec ESP-encrypted transport to access Corporate network resources Direct Access Server Server 2008 R2 DC & DNS (Server 2008 SP2/R2)

Deployment RequirementsDC/DNS Needs at least one W2K8 SP2 or R2 DC/DNS server for client registration of V6 recordsNeeds at least one W2K8 SP2 or R2 DC/DNS server for client registration of V6 records Network Infrastructure Can be IPv4 because we deploy ISATAP with DirectAccessCan be IPv4 because we deploy ISATAP with DirectAccessNAT-PT Can be used to provide access to IPv4-only resourcesCan be used to provide access to IPv4-only resources

Name Resolution

Name Resolution Policy Table (NRPT) New feature in Windows 7 Used by DirectAccess Client to determine ‘which’ DNS Server to use based on namespace New name resolution order: Local cache Hosts file NRPT DNS

NRPT For any given query, if the domain matches an entry in the NRPT, the query will be sent to the DNS Servers specified in the NRPT These are internal DNS servers – they do not need to be dedicated to DirectAccess, and they do not need to be in the DMZ If the name doesn't match an NRPT entry, the query will be sent to the DNS server configured for the interface Corp.contoso.com2001:1:1::b3df 2001:1:1::b3de

Diagnostics

Internet Explorer Diagnose Problem Button It has been enhanced to troubleshoot DirectAccess Networking Icon (right click) Troubleshoot problems option. Supports providing a location. Also has a DirectAccess Entry Point Control Panel, Troubleshooting Connect to a Workplace place using DirectAccess Command Prompt (Elevated) NETSH TRACE START SCENARIO=DIRECTACCESS
